The Ship of Theseus

2 Mar

 

Hello everyone! I know I have not done anything here for awhile, and it is for a good reason. My plan here from now on is to only post here a few things I have already written for school or other reasons, or to only post when I have extreme leisure time available.

I am currently in the process of beginning a book I have decided to write. This involves a strikingly different metaphysical theory inferred from an in depth analysis of the consciousness. This will either make me post here even less or, make me post here more. If you want more frequent yet shorter things from this crazy brain of mine you can follow me on tumblr:

below is an analysis of the metaphysics of identity of the puzzle of the ship of Theseus.

 

When Theseus, hero of Athens, last sailed his ship and left it in the harbor in Athens, the ship was left there long after his death. When the ship’s planks decayed to a point, it was renovated with new planks so Theseus’ ship would be maintained. The history of that ship led to the puzzle that has caused debate among metaphysicians as to the identity of the original ship and where the identity was after the original ship was renovated. The original ship was renovated one at a time with a new plank replacing an old decayed plank. This was done until a new renovated ship remained. For the purpose of the puzzle, the action of placing the old decayed planks of the old ship in a warehouse and then reconstructing a ship exactly the same with those same old planks is discussed also. This leads to there being two ships (one reconstructed and one renovated) and a puzzle as to which one is the ‘original’ ship that Theseus sailed. This puzzle is useful in debate for metaphysics of identity between particulars (identity of a thing to itself and identity of a thing to other things based on principles like Leibniz’s law). There is debate between people that think that the original ship is the renovated ship or the reconstructed ship for a few good reasons. One large question is as to whether an object’s identity survives the replacement of the object’s parts, and another is to whether objects can maintain identity in intermittent existences. These and other things matter a lot in arguing for any position that could possibly solve this puzzle.

Since no one conclusion can be achieved that solves this puzzle without some further objection, both arguments are worth exploring. At present, I will explore both sides of the argument yet argue for the reconstructed ship being the original. I will argue the following argument and refute its objections:

  1. If x has exactly the same parts as y, then x=y
  2. The reconstructed ship has exactly the same parts as the original ship
  3. Therefore, the reconstructed ship = the original ship

This argument obviously favors the reconstructed ship being the original ship, but objections and counter-arguments need to be taken into consideration before proclaiming this argument to be a better solution to the puzzle.

Before going through the argument premise by premise, it is worthy to note that this puzzle as it corresponds to metaphysics and identity is important as the ships’ numerical and qualitative identities. Objects are often understood as composite objects because of how many parts are understood as one composite object together as a whole. Two objects, or an object and itself, are numerically identical if the objects as composites are the same (e.g. a banana is numerically identical to itself when it goes from its green color to yellow). Two objects are qualitatively different when parts or qualities within a composite object are different between two objects or an object and itself at a later time. The banana is not qualitatively identical to itself between its time as a green banana and its time as a ripe yellow one. Keeping these terms in mind going further, it is also worthy to note that this argument for the reconstructed ship is valid as its conclusion follows from the two premises.

The first premise (if x has the same parts as y, then x=y) is generally a common sense principle. Lowe in A Survey of Metaphysics uses examples of ancient artifacts and the restoration of them. When an artifact is restored (taken apart then put back together where x is the artifact before disassembling and y is the artifact after reassembling), the newly reconstructed artifact is considered still the original artifact that was excavated. Numerical identity seems to subsume qualitative identity in that the composite whole of an object gets its numerical identity from the parts that make it up. The parts of an object matter to the whole identity of an object, therefore, this premise is favorable. Objections come from the possibility of a composite object being disassembled (i.e. the ship of Theseus) and then reassembled. X and Y would still have their same parts, but their identity may have been lost between disassembling and reassembling. One might object by asking where the existence of the object went from the time the object was disassembled up to the time it was reassembled. The replacement of an object’s parts brings further objections.

The second premise (the reconstructed ship has the same parts as the original ship) is simply an example of the first premise that states that when an object has the same parts as another object then those two objects equal each other. Since qualitative identity is seemingly subsumed by numerical identity, the reconstructed ship will end up debatably having the same numerical identity as the original ship. One large question that divides the arguments of the puzzle of Theseus’ ship is whether or not an object’s identity can survive the replacement of its parts. One arguing that the reconstructed ship is the original ship is saying that an object’s identity cannot survive the replacement of parts. On this view, once the parts are replaced an intermittent existence is allowed for the object as its original parts are disassembled where the object still exists but is simply on existential hiatus. This violates a common sense principle because an intermittent existence is sometimes thought of as a ‘ceasing to exist’ and a ‘coming back into existence’ allowed for the object that violates many things philosophers have already stated. These two big questions create the dividing line between the two sides of the puzzle.

From the previous two premises, it is easy to see how this conclusion follows: Therefore, the reconstructed ship = original ship. This conclusion to the puzzle is arguable because it is numerically identical as well as qualitatively identical to the original ship. It has all the same parts making the composite object equal to that of the original ship. The renovated ship has both of these kinds of identity but has less qualitative identity because of the set of different parts it was given during renovation. Concluding by saying that the reconstructed ship is the original is saying that the object’s identity cannot survive the replacement of parts because of the changes of qualitative identity. Concluding this is also saying that intermittent existences are allowed and are not equivalent to a contradictory ‘coming into existence’ and ‘ceasing to exist.’ This conclusion is also saying that the original ship cannot be both renovated and reconstructed ships because one identity cannot be in two spatial locations at once. This is also saying that it cannot be neither the renovated nor the reconstructed ship because that conclusion would cause one to stop using general common sense.

Whether one thinks the original ship is the renovated or the reconstructed it comes down to whether that person thinks objects can have intermittent existences and whether object’s identities can survive replacement of parts. Having discussed this argument and its objections it is clear why one would argue either stance. My argument is in agreement with the current argument discussed. When thinking about metaphysical identity at all it is easy to see how and why numerical identity subsumes qualitative identity. Because of this, I do not agree that the object’s identity survives the replacement of its parts. The renovated ship after replacement has differences of qualitative identity from the original ship because of the entirety of different parts even if renovated in the same structure as the original ship. The parts of the ship contribute to its qualitative identity. Furthermore, I agree that objects are allowed intermittent existences and during existences such as these a composite object does not cease to exist or come back into existence when restructured. When the original ship was renovated, each part removed from the ship was taking a little bit of the original ship’s identity little by little.  The identity of the original ship stood with the old decayed planks in the warehouse that were reconstructed. All of this comes down to the argument that the identity of the ship is in the planks that made up its parts and the whole composite object. The renovated ship with new planks is a new composite object with new parts and thus a new identity. Even though there are objections to this stance, one identity cannot be identical to a qualitatively different one.

 

Ayer’s Function of Philosophy in Language, Truth, and Logic ( A Metaphilosophy #2)

2 Dec

I am writing a few things here on my free of obligations thursday so that I can get some posts in before I won’t be able to write anything for about a month (I think). This is simply because I have a ton of school things to do for the next 2 weeks and then I will have Christmas break and will have little time.  I will for sure come back to writing by the week of January 10.

I want to talk about an aspect of another section in A.J. Ayer’s Language Truth and Logic. The second section of the book is the Function of Philosophy. I find this interesting because metaphilosophy and finding out what the goal of philosophy is should be held dear by any philosopher. Again showing his rejection for metaphysics Ayer states that the function for philosophy is not to find insight on metaphysical things. Ayer says that the search for a first philosophy is not really the goal. First philosophy is the kind of philosophizing Descartes did in his meditations.

Ayer proclaims philosophy to be a critic. This is for one thing towards scientific propositions where philosophy is used to critique the sciences and make it better. Mostly, he states philosophy to be a critic in that it tells one whether their beliefs are  ‘self consistent’ or not, and that it shows the things we use to find the truth ( or lack thereof) in our propositions. This function of philosophy contributes to science and critiques things one scientifically proposes. Ayer seems to be defending against the idea that science cannot do without philosophy because of induction. He goes on to say that induction cannot be solved, and we should deal with it in science and philosophy is not really needed for this purpose.

Others in the logical positivist era and before it have maintained the idea that science can do without philosophy and simply that philosophy assists philosophy by critiquing it and making it the best it possibly can be. In the beginning of logical positivism, the Vienna Circle (influenced by Mach and Wittgenstein, and including Carnap, Hempel, Schlick and others) wrote the Scientific Conception of the World. “The goal ahead is a unified science. the endeavor is to link and harmonize  the achievements of individual investigators in their various fields of science. From this aim follows the emphasis on collective efforts, and also the emphasis on what can be grasped intersubjectively; from this springs the search for a neutral system of formulae, for a symbolism freed from the slag of historical languages; and also the search for a total system of concepts.” This I quoted from the Scientific Conception of the World. The aim these scientists show to have is to give philosophy a goal to contribute in this unified science with physics, chemistry and all other sciences contributing in any specific theory. Philosophy just seems here to be one of many parts of a collective effort. Philosophy plays a huge part in this collective effort in that its theories can contribute to any kind of discipline or science. Did I mention the members of the Vienna Circle rejected metaphysics too? Its what all the positivists were doing. If your friends jumped off a bridge would you do it too? I am simply joking because of how many people in the logical positivist era who advocated a verification, an a priori epistemology, and the rejection and elimination of all metaphysics and its pseudo-statements. I can understand why they feel the need to remove metaphysics from philosophy because science does some of metaphysics’ roles in the most logical way possible (I am kind of being facetious). A unified science achieved by collective efforts among many sciences and disciplines is one goal philosophy has. This should not involve the rejection of metaphysics however.

Putting science aside, I feel philosophy is not simply an additive profession used to critique and assist scientific experimentation and exploration. In mostly non-metaphysical aspects of philosophy, there are roles in philosophy made specifically for the critique and use in science, but an underlying goal or purpose exists under all specialized goals and roles the specific kinds of philosophy has (such as I feel the Vienna Circle refers to the philosophy of science and not really to the rest of philosophy as they may have thought). The huge purpose philosophy seems to me to have is the role in doing what science and experimentation cannot.  Science cannot prove the existence of noumenal beings or transcendent realities but philosophy actually has a chance at doing just that. If one uses the intersection of metaphysics and epistemology along with some ethics (and of course logic as the foundation of understandings) to postulate upon our empirical and un-empirical observations, things can be discovered that science cannot measure up to. This is why I think the unified science by the collective efforts of all disciplines including philosophy is the best combination because science being paired with philosophy can yield great results. Philosophical propositions can be experimented sometimes scientifically and proved out.

I totally advocate the unified science proposed by the Vienna Circle, but instead of eliminating half of the entire body of philosophy, it should be revitalized and used toward science’s benefit. Metaphysics can be beneficial to scientists as can some religion.  Philosophy should be used whenever possible in all disciplines of science.

I have interest in metaphilosophy to help philosophers define and redefine the purpose being driven toward. I want to keep addressing themes in metaphilosophy here every once in awhile to keep thoughts on track. Each philosopher regardless of situation has his or her own course of action to take to complete a philosophical project or work. I have my own so I feel it necessary to keep metaphilosophically addressing philosophy right now, and the philosophy I currently pursue.

What function or goal do you think philosophy should have?

A.J. Ayer’s Language, Truth, and Logic: Elimination of Metaphysics

30 Nov

I return, once again, yes again, to Mr. Alfred Jules Ayer. I am now interested in his book he wrote in his twenties Language Truth and Logic. Reading it, the first section addresses metaphysics and why it sucks.

What a positivist.

I have two bones to pick with the first section of Ayer’s book, but he goes over more things than I am particularly concerned with. He begins to discredit the metaphysician  by stating that they attempt to get into the transcendent reality (unseen unempirical reality) when we create our propositions by our senses. When we feel we are limited to our 5 senses, postulating about anything other than empirical matters can be something hard to muster. Ayer claims that if one cannot really or worthily postulate about anything unempirical, most metaphysics conducts philosophies of pseudo-statement where nothing is really proclaimed and nothing can be argued for or against because again nothing is really proclaimed. From this discussion of most metaphysics as crappy pseudo-statements Ayer goes on to saying that statements and propositions made in metaphysics and epistemology must have a process of verification. He then goes into aspects of verification ( like application and other things).

Like I said, what a positivist (trying to kill metaphysics and trying to verify statements).

I have said before, I have 2 opinions differing from Ayer. 1) must all propositions be derived from sensory perception?

2)Verification is a lost cause.

In the beginning of the section Elimination of Metaphysics, Ayer stated that if most propositions are derived from sensory perception, transcendent realities cannot be understood or postulated about. Not to say that we have a 6th sense, but there are senses and feelings beyond the 5 senses we all know (sight, sound, smell, touch, sound). The main five tell us things about phenomenal reality, but there are things we have that can lead us to postulations about noumenal reality. When I say noumenal reality, I mean reality we cannot empirically perceive. I hate to exemplify this because I will be called dumb, but one might be a conversation indirectly or directly between a God and man. This is not of th 5 senses. This can note an existence of a God, and a heaven. Another example is God talking to a man and sending him to a very dark place (i.e. Hell) and then bringing him back. These observations are not empirical. This would lead me to question does one have the 5 senses beyond the body and when the soul is relocated? I think not, and it is just that everything is made known to the soul of what is around it. This is all hard to explain because empirically understood people will not understand. A connection between a God and a man, or a relocation to another space, is personally experienced only with the soul present, and cannot be understood to a man who has not experienced it himself.

I have only experienced an indirect conversation with God. In a hard time of problems in my life, and constantly praying to God for answers, my prayers were answered as I immediately understood wholly my situation and what I needed to do from there on out. It is almost as if I had a close experience with God to the point that I cannot explain it to any other than myself. These experiences are examples of what can lead us into inferring a noumenal space not empirically observed by people.

My point is that not all propositions have to be derived from empirical observations. It isn’t like we can chose to observe unempirically a noumenal place or being, but it happens at the will of God and other beings there. I do not mean to reject Ayer’s argument solely on religious inferences, but I mean to reject it by saying that if people have conceived of beings and places unempirical and not phenomenal before, it  can happen again even if its not at our will.

This leads me to verification, the Holy Grail of the logical positivists. Quine and other philosophers have shown the with meaning and other things in verification, it is just not a feasible project for metaphysical and epistemological propositions.  Verification can be done, but only on a personal basis, or a local basis between a few people who have experienced the same things. If verification of statements can only be done on such local or personal bases, there is little point to continuing on the quest for verification. Meaning has been solved, as has justification and criterion of application, and how these are applied has also been solved, but using all of these things in verification is what I understand as a pointless endeavor.

Going back to the noumenal perceptions that I believe people (including myself) to have, if these noumena unempirical perceptions are there mixed with the phenomenal ones, propositions become personal. Once these propositions about the world phenomenal or noumenal become personal, verification is a pointless endeavor.  It cannot be done, and one would be continuously be searching for that last part to verify a proposition.

Where does this leave a person who wants to know things about the world?

Still with a bright future I think (I haven’t even addressed the current foundationalism vs. coherentism, and internalism vs. externalism yet but nonetheless this is a totally different course of action in postulating things about the world). The fact that propositions cannot be verified only means that single propositions cannot be verified because of personal aspects with noumenal facts. Various propositions grouped together are what actually can tell one something about the world. Plethoras of propositions put together that while aren’t verified alone, can overlap and tell people something about the phenomenal or noumenal world. Or at least this is what I think, not taking into account any other philosophies.

Let me guess what you’re thinking, “Bullshit”. Did I hit the nail on the head?

Noumenal metaphysics is something totally feasible, just not entirely by empirical observation. Empirical observation is the short cut in all epistemology crossing with metaphysics, and it is also seen as the only way, when really it is one among many.

Thanks for the support. I have not a clue when I shall write again as my college papers are coming closer to their due dates and I will have less time.

 

Charles Iroegbu’s Neo Classification of Beings

18 Nov

I feel like I should make aware to my readers the communication I have had with Charles Iroegbu. Charles contacted me after reading my Classification of Beings writing that I posted here awhile back. He wrote an article on the same subject of his own. He asked me to look at it and I did. He also wanted me to put it on Google Docs for him, and I did so as well. The document can be found on Google at this link:  https://docs.google.com/document/d/1jdkmWX-BYBgOyss0OzYHiR7AUKVNCi3HTUDE97zq3CU/edit?hl=en&pli=1#

I want to discuss my feelings about it, but do not continue reading until you have taken a look at the link where Charles’  article is. He goes to the University of Nigeria by the way.

Charles classified beings closely similar to the way I did. He distinguished a God being, a Death being, a Human being, an animo-plant being, and a lifeless being. He calls things differently than I do, but his view metaphysically parallels mine. The God being is of course the unmoved mover and the God that I constantly refer to. The death being is the spirits that have left the human being state. The human being is obviously the state of life that we as humans are all in where our bodies are not separated from our souls. The animo-plant being is what I would describe as the beings with non-nous souls. The lifeless being is the beings that of course have no life such as the desk my computer sits on.

What I really like about Charles’ understanding of the classification of the world metaphysically, is that he goes against Aristotelian thought that the body is too personalized to be separated from the soul.  Near death experiences that some have had where they experience the leaving of their body towards a somewhat spiritual world would not be explainable if the body were together forever with the soul.

Charles discusses being really only in terms of ontological existence. When I wrote my classification of beings, I classified things in three ways, by  location in the cosmos, matter making up the being, and spirit. Charles mostly discusses beings based on their spiritual status. The God being is an all powerful omnipotent spirit. The Death being is spirit after physical life after death. The human being is spirit before death. The animo-plant being is spirit without intelligence. The lifeless being is what confused me as to his mode of classification.  The lifeless being is of no spirit at all, so I am understanding that Charles is classifying things based on their mere ontological status.

I should not have a problem here really because it is my opinion that whatever is experienced or observed is ontologically existent at one time or another. Maybe my classification of beings was more complex than necessary because of how I broke things up into three modes of classification. Charles simplifies things because of how he reduces classification down to level of ontological existence.

And they are all real at one time or another because they whatever is seen is actualized existence. The metaphysical classification of being by Charles is basically a reduction of metaphysics to a level of ontology.

Thanks for the support, and thanks to Charles Iroegbu for contacting me.

Analyticity and Quine’s Rejection of the Dogma

16 Nov

I have succumbed somewhat to the understanding that there really is no meaning in anything. I used to think everything had meaning, but after studying W.V. Quine, I understand better why meaning cannot really exist.  If one reads and understands Quine’s On What There Is and Two Dogmas of Empiricism that one person must come up with some big evidence to actually prove that one truth statement can mean another or do any other function that meaning has said to have. This comes from Quine because of the two dogmas: 1) analyticity, and 2) reductionism. My concern here is analyticity and to help myself and the reader of this writing to understand why analyticity can be shown false and can also show ‘meaning’ to be a false hope.

If you have read Kant or other philosophers analytic statements are easy to understand. I understand them as things I can come to understand without having to go through a logical process of factual evaluation. If I hold a red pen up, I can see it and know “this is a red pen” without any logical process of fact evaluation. I know it like the snap of two fingers. Synthetic is just the opposite where factual and logical processes of evaluation must be executed to understand it. Quine defines the analytic in a somewhat different fashion which I can fathom clearly:

“Kant conceived of an analytic statement as one that attributes to its subject no more than is already conceptually contained in the subject. This formulation has two shortcomings: it limits itself to statements to subject-predicate form, and it appeals to a notion of containment which is left at a metaphorical level. But Kant’s intent, evident more from the use he makes of the notion of analyticity than from his definition of it, can be restated thus: a statement is analytic when it is true by virtue of meanings and independently of fact” (Quine).

So ultimately what I want you to get from that quote is that the analytic is statements that are true ‘by virtue of meaning’ and ‘independently of fact.’ Most important is that analytic statements are said to be true by virtue of their meanings. This has so much importance because Quine attacks the use of the word meaning because it is loosely and not well understood or defined.  In Two Dogmas of Empiricism he ultimately concludes that there is no meaning at all. He rejects not only reductionism but also analyticity. He rejects analyticity by rejecting meaning. He rejects meaning by talking about why certain logical truths and synonymies are not meaning and can not be meaning.

Beginning with logical truths he discusses reference and extension to not be meaning. Logical truths are exemplified by Quine with Morning Star and Evening Star. They both are sightings of the planet Venus, and they both are names for Venus, and both refer to Venus. Morning Star does not mean Evening Star or Venus.  This is just naming or reference. These things like certain logical truths and synonymy have been posed as clarification and understanding for what meaning is, and Quine simply paints these as failures to define and understand meaning. Reference and naming are both of singular terms. Extension is a logical truth that is of predicates. Extension is often thought to be meaning. An example of extension would be creating 2 truths about a certain entity as Quine puts it, but he paints this as another failure to understand meaning. If I am talking about a man, 2 logical truths about it would be ‘a creature with a brain’ and ‘a creature with a stomach’. Both statements extend to the same ‘entity’ but just because this is so does not mean that they mean man. These are obvious logical truths that Quine says is not meaning.

Besides logical truths, Quine says that synonymy and definition are also not meaning. He talks about definition and then interchangeability with synonymy. Synonymy is obviously understood because things like bachelor and unmarried man are synonymous, but the question is does synonymy entail meaning. Quine states definition to not be meaning because of what the lexicographer (dictionary writer) does. A definition for a word is just a section of a long chain of synonymies:

” In formal and informal work alike, thus, we find that definition – except in the extreme case of the explicitly conventional introduction of new notations – hinges on prior relationships of synonymy. Recognizing then that the notion of definition does not hold the key to synonymy and analyticity” (Quine).

S0 definition is not at all meaning because of how definition continues from word to word and phrase to phrase and being referred to those because of the synonymies that create the huge chain. Definition is just related to more synonymies and does not have meaning and cannot hold analyticity in any defined word or phrase. Definition and its relation to prior relationships of synonymy are more easily understood when it is understood why most synonymies are not meaning.

Definition not being meaning, Quine goes on to specific synonymies. Interchangeability is a certain kind of synonymy that Quine proves to not be meaning. He goes as specific to talk about interchangeability salva veritatae or interchangeability preserving truth. He declares the synonymy in interchangeability salva veritatae, but no meaning at all. For example, ‘bachelor’ and ‘unmarried man’ are interchangeable salva veritate and synonymous of course, but they are not meaning because what if bachelor is referring to ‘bachelor of arts’, ‘bachelor of science’, or ‘bachelors buttons’ as Quine puts it. In those cases bachelor would not mean unmarried man, so synonymy in the case of interchangeability salva veritatae is not meaning. He also includes that interchangeability salva necesitatae or interchangeability preserving necessity is synonymy yet not meaning because necessity is confusing as to its meaning and causes problems. The issue here is that interchangeability is synonymy yet its not meaning because some words can be synonymous and interchangeable yet not really mean the same thing. He declares this to make difficult the understanding of what meaning is.

Quine continues with his discussion about meaning and synonymy and his rejection of analyticity. I could talk for a long time about it, but I simply want to discuss the basics to understand why he rejects analyticity. In the end of the essay he uses his premises to say that the boundary between analytic and synthetic has never really been drawn. There have been attempts at defining the two in making the boundary, but clarifications have not been given to really make that dreaded distinction. If you read Two Dogmas of Empiricism by Quine and get nothing else out of it, if you get out of it that there is no meaning, then that is good enough.

I think that there is analyticity. If a person understands philosophy that person has their own understanding of the analytic/synthetic distinction that is difficult to put into words good enough to convey understanding of it from one person to another. I really think that there is analytic while at the same time it can be proven that there is not. I have my understanding of analytic and can understand why there is no analytic. Analyticity is a complicated subject because understandings of it are not the same between people.

Coming to an opinion about whether one thinks analytic exists is a difficult one especially because deciding whether one thinks there is meaning is an equally hard thing. Meaning is a hard thing to define or understand because of issues of logical truths and synonymies exemplified by Quine. My opinion is that there is no meaning and that it is all synonymy or logical truths of one form or another. Meaning is like analytic in that it can be understood by a person but not well put into words. I feel like I can understand meaning, but then I can logically reject it at the same time.

What do you think? Do you think there is analytically true statements? or meaning in general?  I am stuck and do not know what my stance on the issue is because I read Quine’s great rationalization on why analyticity, meaning and reductionism are not in existence and then at the same time I can think as if they do.  I am just not sure and need further contemplation.

G.E. Moore’s Proof of an External World: If we cannot prove it, can we know it?

3 Nov

I have previously discussed Wittgenstein’s book On Certainty that he wrote towards the end of his life, where he gets his frustration out mostly by correcting Moore’s essay Proof of an External World (and A Defense of Common Sense).  I am looking at Moore’s essay and looking at beginning propositions of Wittgenstein’s On Certainty and thinking about their arguments.  What Moore’s essay ultimately boils down to is him saying that he can know things without proving them. He bases that upon his idea of rigorously proving things along with other things.

Moore begins by saying that he can prove the entire external world by saying “I have one hand here, and another here.” He says this and then says that what he said conforms to a rigorous proof. “I can prove now, for instance, that two human hands exist. How? By holding up my two hands, and saying, as I make a certain gesture with the right hand, “Here is one hand”, and adding, as I make certain gesture with the left, “and here is another”. And if, by doing this, I have proved ipso facto  the existence of external things, you will all see that I can also do it now in numbers of other ways: there  is no need to multiply examples” (Moore).  He then states that what he just said was a “rigorous proof” for the external existence of 2 hands. He proceeds even further to state what qualifications for a rigorous proof are: “Of, course it would not have been a proof unless three conditions were satisfied; namely (1) unless the premiss which I adduced as proof of the conclusion was different from the conclusion I adduced it to prove”, so in short, the conclusion is different from the discussed premise,”….; (2) unless the premiss with I adduced was something which I knew to be the case, and not merely something which I believed but which was by no means certain, or something which, though in fact true, I did not know to be so;” in short  you are certain about the premise, which certainty and knowing is the ultimate discussion about Moore’s paper, and I shall further discuss here later, “…and (3) unless the conclusion did really follow from the premiss” (Moore). So, to Moore, for a rigorous proof, the conclusion and premise must be different,  you are certain of the premise, and the conclusion follows from the premise. If, in ones argument, you can satisfy these three requirements, to Moore, you have proven what you have been trying to prove.

Going on in the essay Moore talks about why his proof is good, and how proving that something existed in the past external world helps him with his present proof. All of this leads up to the final paragraph of the essay where Wittgenstein and others get most of their food for argument. I will simply cite it and discuss it thereafter:

“But another reason why some people would feel dissatisfied with my proofs is, I think, not merely that they want a proof of something which I haven’t proved, but that they think that, if I cannot give such extra proofs, then the proofs that I have given are not conclusive proofs at all. And this, I think, is a definite mistake. They would say: ” If you cannot prove your premiss that here is one hand and here is another, then you do not know it. But you yourself have admitted that, if you did not know it, then your proof was not conclusive. Therefore, your proof was not, as you say it was, a conclusive proof.” This view that, if I cannot prove such things as these, I do not know them, is, I think, the view that Kant was expressing in the sentence which I quoted at the beginning of this lecture, when he implies that so long as we have no proof of the existence of external things, their existence must be accepted merely on faith. He means to say, I think, that if I cannot prove that there is a hand here, I must accept it merely as a matter of faith – I cannot know it. Such a view, thought it has been very common among philosophers, can, I think, be shown to be wrong – though shown only by the use of premisses which are not known to be true, unless we do know of the existence of external things. I can know things, which I cannot prove; and among things which I certainly did know, even if (as I think) I could not prove them, were the premises of my two proofs. I should say, therefore, that those, if any, who are dissatisfied with these proofs merely on the ground that I did not know their premisses, have no good reason for their dissatisfaction” (Moore).

The entirety of this ending section of the paper refers to what one says when saying “I know.” His opposition says that one only knows when it is proven, and when premises cannot be proven, the whole conclusion is proven. Responding to all of these oppositions to his proving qualifications and to how he gauges how he knows something, he ends up referring to Kant’s statement that when one cannot prove something, one does not know it, and must resort to having mere faith. Thinking back to Kant’s discussion of noumena, we cannot know of their existence and we must understand that there are ways of understanding things beyond empirical observation. Kant talks about faith when introducing noumena in that noumena cannot be really known. Moore talks about Kant when defending his argument (not necessarily the part in Kant’s work about noumena) by saying that if he has faith in his right hand being there, he can still know it.

Using again the phrase “what this boils down to”, what this boils down to is that what can be proven (proven rigorously beyond what Moore defines as rigorously proving in that the premises are proven in different ways to help prove even more the ending conclusion) is known, and what cannot be proven can be known in a way less strict sense (not with all the logical proofs) where we have faith in it, yet it is not really strictly Wittgensteinian defined ‘known’, yet Moore thinks with faith, one can ‘know’ in all forms of the word what cannot be rigorously logically proven.

Kant thought that faith did not lead to proving or knowing an external thing, Moore thought that faith led still to knowing external things, and Wittgenstein overwhelmingly trampled on Moore’s opinion here with his book On Certainty. I think that when looking at these few arguments about what it means to ‘know’ anything, the word ‘know’ should be thought of and use in the strictest sense especially when trying to understand the arguments and formulate individual opinions on them. Moore thinks of ‘knowing’ something as not having consistent proof (in my opinion) but having faith in things such as that there is a right hand here. Kant believes in faith being there for minimal understanding, but it doesn’t denote ‘knowing’. Finally, in Wittgenstein’s On Certainty he makes the word know, knowing, knowledge and any other words like it to be as strict as possible.

Here are only a few propositions in the book’s entire discussion about knowledge and certainty that stomps on Moore’s argument:

”  14.  That he does know takes some shewing.

15. It needs to be shewn that no mistake was possible. Giving the assurance “I know” doesn’t suffice. For it is after all only an assurance that I can’t be making a mistake, and it needs to be objectively established that I am not making a mistake about that.”

Wittgenstein goes on to cite Moore and say more things about his argument. One thing I want to make known about Wittgenstein’s argument is that he thinks that Moore’s use of know, knowing, and knowledge is redundant, repetitive, and does not help his overall argument. If you have a library near you, like a college library, it probably has a philosophy section and may have On Certainty by Wittgenstein, or if you have the means pick it up. To get Moore’s essay Proof of an External World go here:  http://faculty.uml.edu/enelson/g%20e%20moore,%20external%20world.pdf I say that because there are many arguments that Wittgenstein specifically picks on from Moore’s essay, and there are many other things to think about and discuss besides the single point I am going to make from here on out, so if you want a more wholly picture of Moore’s opinion and Wittgenstein’s opinion, read the essay and read some of the book (since I do not think reading all of On Certainty is necessary and if you want to read a whole book of Wittgenstein read Tractatus Logic0-Philosophicus).

First of all, my opinion is that Moore’s proof of an external world and his qualifications for a proof that he used are faulty in actually making knowledge of external things. It all comes down to that Moore does not feel the need to prove his premises, and then he says that having faith is proof of external things, and it is knowing external things. I am a large holder of faith in things I have not empirically observed and proven, the only reason being that I have not found a way to prove their external existences beyond faith. Faith is similar but not equal to knowledge, and I think that when one says that faith equals knowledge, it is merely a cop out in that that person will not take further efforts to come up with logical proofs for what one has faith in.

Its hard to say how much proof there is in faith, and how much knowledge there can be had in any faith at its face value. This is because faith varies from what faith is had in, how the faith is had, and a plethora of other factors that go into faith in one thing. If I have faith in God, which I do, I feel like I have total knowledge about Him yet I do not have logical rigorous proofs for it. I feel like I have full knowledge because of my intimate and loving faith in Him, but I want to create a logical process for further proof of things others might not see but I still have faith in. Moore just says that faith equals knowing things external, but that leads to ridicule from logically sensible philosophers and people like Wittgenstein. This tells me that faith feels sufficient for knowledge to those who have faith in something external, but if we want to show others about this thing and prove it to others for the entire benefit for everyone and ourselves, we need a logical process to create a rigorous proof for things’ existences like God.

In the end,  I hate to say this, but faith is not sufficient for true knowledge in its strictest sense. Moore is copping out philosophically when he says that faith is equal to knowledge.  Wittgenstein isn’t really getting there either when he tramples on Moore’s argument rather than just removing a few things, polishing it, and building upon it.

I do not know what that logical process towards a rigorous proof of external things not empirically observed would be, but I think it should be something philosophers and logicians should progress toward. It would be nice to have logically rigorous proofs for noumena and God, or even monads and forms. Then metaphysics would be generally more accepted rather than rejected. This is a difficult thing to just say should happen, but I think it should have efforts put toward it rather than just saying that faith is knowledge.

To actually figure out how  to prove external things that are phenomena or noumena, it is my opinion that our sensations should be analyzed more than they ever have been. I say this to mean that we should analyze sensations beyond just the six senses. I like to think of it in the way that we should look at our impressions  (using Hume’s term in the Origin of Our Ideas). Impressions being things entering our perception with most violence and force. Impressions are what I take to be emotions, passions, feelings, and sensations. For example, I find an impression to be the event that one has a direct or indirect conversation with God. I have not had a direct one, but others I know have. An indirect one I have had is where I ask Him for something in particular to really help my horrible situation out. After not getting it for awhile and asking Him again, soon after, it immediately occurs and I immediately realize why He waited until now and why he put me in the problem initially. Along with this understanding, I would have amazing emotional feeling because  I can feel the things that have happened before me, and I know from who they come. This is one example of an impression that I think should be examined further to get from faith in noumenal external things to actual knowledge in the Wittgensteinian sense.

I just think that faith does not denote knowledge even if it gives us real pure understanding.

Thanks for the support, and my apologies if this was too long.

A.J. Ayer and the Act Object Analysis of Sensation

3 Nov

Here I am referring back to Ayer’s Phenomenalism, yet just another aspect in his entire argument that I have explained before. In case you did not know, I started another website http://herodotean.wordpress.com where I talk about history, politics, and current news.

Ayer begins Phenomenalism with a discussion about Bertrand Russell’s definition of sense data where he describes them as “objects of acquaintance.” He finds confusion and need for further explanation with Russell’s sense data because this implies that he is describing sense data as objects of knowledge. For something to be an object of knowledge, Ayer says,  it is something that we know to be or not be the case. Ayer states that knowing things is something meaningless to say, and therefore there are no objects of knowledge.

This all leads to Ayer’s conclusion that it  “is meaningless to speak of knowing objects.” He continues further: ” Failure to realize this has contributed , I think, to a famous piece of philosophical mythology, the act-object analysis of sensation. For once it is assumed that having a sensation involves knowing an object, then it may seem reasonable to apply to this case the principle that what is known must be independent  of the knowing of it…..”

This at first implies that its meaningless to talk about knowing objects, because knowing objects involves saying that it is or isn’t the case in certain situations, or it means knowing it in other ways, making it entirely meaningless. Ayer talks about knowing being a transitive verb carrying many meanings that are variously used by philosophers and people that do not philosophize creating many confusions. All of this together makes it meaningless to talk about knowing things. This leads further to say that we often assume that knowing an object always involves  having a sensation. Finally, the act object analysis of sensation says that what is known, call it A, can be thought that because of all of the above, is independent of the action of knowing it.  Because of all this A is thought to be independent from the action of knowing it.

Because we cannot really talk about knowing objects, we are lead to this act object analysis of sensation where the act of sensing an object is separate from the actual object.  I like to think of this as if the act of sensing an object was  a part of, or dependent on, the object. If this is the case in any sensation, the object cannot have any postulates made upon it as to whether or not it is a real object that can be known.

If the act and the object are together and dependent on each other, we cannot speak of knowing an object, because most likely the object is not real anyway. Ayer seems to think that this is the best way to go about thinking about things. If this were the other way, where the act and object are separate and independent, this would imply that an object may be out there to be known, and the act would be used for just that purpose.

Ayer states that the act and object cannot be independent or separate because this would lead to objects being able to be known. To Ayer, however, objects cannot be discussed as to how they can be known.

First, I do not know how meaningless it is to discuss knowing objects. Because of how transitive of a verb knowing is, I think it needs much clarification as to what knowing means when talking about sense data and objects. Ayer only says that its meaningless to talk about objects being known because of how physical objects are logical constructions of sense data, and he wants to end discussion about objects in the beginning words of his essay.  I disagree here, because I think objects can be discussed as to if we know certain ones or not. What we mean when we say we know of an object needs to be clarified. I think it should be clarified to say the following: knowing an object is the apprehension of an actualized existence or being.

This view is contrary to Ayer’s and it endorses a modal realism discussed by David Lewis. Lewis states in On the Plurality of Worlds that each thing we see is an actualization of a being in one way or another. When we see anything, we are apprehending objects that are existent. This would lead me to think that the act of seeing an object and the object itself are totally independent…..

This is true in most cases I think. Lewis’s modal realism would still work in the case that the act of seeing the object and the object itself are dependent and together. This scenario I think is existent in the case that one is hallucinating, dreaming, or seeing anything usually not actualized. Any hallucination or dream is still an actualized existence, even if the act of seeing it, and the seen object are dependent and together.

All in all, I disagree with Ayer’s originating proposition that begins discussion of the act object analysis of sensation. When Ayer says that discussion of knowing objects is meaningless, I think he is wrong. Yes ‘knowing’ is a confusing transitive verb that has meanings that can be confused between each other, but this only needs clarification to return to discussion of knowing objects. Anyway, I think we can know objects anyway because we see something all the time that is actualized existences in one way or another. We are always seeing real objects whether the act and object are independent or dependent, together or separate.

This modal realism and its following ontology dismantles Ayer’s thought that discussion about the knowledge of objects is meaningless.

This is only a  tiny part of Ayer’s entire argument in Phenomenalism, but the act-object analysis of sensation making one choose between the two options made me think about it, and how my specific philosophy at the moment totally tears it apart. Hopefully this wasn’t too hard to understand as I am sleepy and incoherent. I shouldn’t be writing in this state of incoherence, but if there are any inconsistencies, misuse of information, or misinformation, please let me know.

David Hume’s Treatise of Human Nature: Origin of our Ideas

2 Nov

I’m treading ground that I have not yet treaded as a thinker and philosopher. I normally have sided and defended Kant in all situations, without having read his empiricist enemies like Locke, Hume or Berkeley. I purchased David Hume’s Treatise of Human Nature this weekend and have been reading it. I want to talk today about the very beginning of it in Of the Origin of our Ideas. I have a problem or two concerning the things he says in this section, but I shall address it all here.

Hume states that all ideas originally come from perceptions. He divides perceptions into impressions and ideas. Impressions: “Those perceptions, which enter with most force and violence, we may name impressions, and under this name I comprehend all our sensations, passions and emotions, as they make their first appearance in the soul. By ideas I mean the faint images of these in thinking and reasoning; such as, for instance, are all the perceptions excited  by the present discourse, excepting only, those which arise from the sight and touch, and excepting the immediate pleasure or uneasiness it may occasion” (Hume).  This distinction between impressions and ideas of our perceptions easily makes us understand what Hume means. Perceptions are things we sense, feel, and understand. An impression, I see it, are obvious things that are made apparent to us, that immediately impresses upon our soul. Ideas are things we achieve through reasoning, logic, and forced understanding. I think about impressions and ideas, and am brought back to Kant’s analytic and synthetic. This connection can help one understand Hume and Kant together even if they both opposed each other in other ways. The impressions immediately impressing upon our souls, need no further understanding or logical processes to ‘get’ them, just like Kant’s analytic. The ideas, needing much reasoning and logical processes, are just like Kant’s synthetic for this reason. The synthetic is like the ideas for another reason I shall explain later that is the dominating thing to understand when reading Hume’s Of the Origin of Our Ideas in the Treatise of Human Nature.

Hume makes a second distinction of perceptions (again just like Kant does) where he divides them into simple and complex. Simple perceptions “…admit of no distinction nor separation.” Simple perceptions do not divide because of how abstract they are.  Complex perceptions may be “….distinguished into parts.” I really like how Hume exemplifies this: ” Tho’ a particular color, taste, and smell are qualities all united together in this apple, ’tis easy to perceive they are not the same, but are at least distinguishable from each other” (Hume). When I first read this, I got an apple out of my fridge, and looked at it and understood what a complex perception is. The entire perception of one logically constructed object, has many perceptions, so I can understand why the whole perception is complex.

Looking further, I can understand and even exemplify a complex idea or complex impression. A complex impression could be, for example, the result perception if you found your significant other with another person, feeling sadness and anger at the same time, and also, having another anger just for the person your significant other is with. That can be broken down to at least 3 simple impressions. I can think of a complex idea also. Such as,  if I was trying to understand sense data, the sense data is making its presence by size, shape, and color before me, and I have to figure out how much it represents a material object, and I would list reasons why it does or does not.

One big claim Hume makes overall in Of the Origin of Our Ideas is: “That all our simple ideas in their first appearance are derived from simple impressions, which are correspondent to them, and which they exactly represent.” More simply, our ideas are derived from our impressions. Impressions intrude our senses, and I think that ideas follow because we always want to make sense of them. Referring back to the complex impression where one finds their significant other with another person, and feeling sadness and anger for the significant other, and anger for the person with the significant other,  ideas will certainly follow from this. Reasoning and logical processes are used to create ideas to fathom what happened. I totally agree with the main drive this section of Treatise of Human Nature has.

I have one issue with it that occurs in the beginning of the section, which I purposely neglected until now. Once Hume distinguished perceptions into impressions and ideas, stating that impressions enter our senses with ultimate force and violence causing X, Y, and Z effects, and stating that ideas are faint perceptions from reason and logical processes of understanding, he made a disclaimer that nullified everything he just said:

” As on the other hand it sometimes happens, that our impressions are so faint and low, that we cannot distinguish them from our ideas.”

Not only does the above nullify his distinction between impressions and ideas, but it nullifies what he states later when he says that ideas are derived from impressions. This statement that he says nonchalantly in the beginning of the section just nullifies everything. If any perception is faint and low, it is probably an idea. I cannot understand why Hume would make this statement because that would blend ideas with impressions and vice versa. Furthermore, since impressions and ideas cannot be distinguished from each other, how can an idea come from an impression. It is my opinion that in the event of an impression, if it is like the analytic (using Kant’s term), it is immediately understood, and any perception beyond that instance, is just idea.  This is a way to distinguish them.

There is no impression that is so faint that it can be blended with ideas. I think Hume made a confusion here. I do not know why, but I prefer Kant’s definition of ideas because of that one sentence that nullifies everything. Because of that one sentence is one reason I felt I should talk about Hume’s division of perceptions anyway.

Thanks for the support, More on Hume’s Treatise of Human nature to come….

Immanuel Kant’s Critique of Pure Reason: Transcendental Aesthetic

29 Oct

This should be just a quick discussion. Transcendental aesthetic to Kant is the study of all intuitions a priori. The transcendental aesthetic is a beginning section of the Critique of Pure Reason where discussions about a priori and a posteriori arise. Given the distinction between a priori and a posteriori, the distinction between analytic and synthetic are also given.

Expositions (transcendentally and metaphysically) are given of space and time. This is done by Kant to evaluate the two based on a priori or otherwise status. I have discussed the space and time and understood by Kant in other  posts, but here I specifically want to discuss a priori, and its pairing with the analytic or synthetic. I cannot specifically remember what I said in those two writings, but again that matters to what I want to talk about. It matters to Kant because it helps in discussion of the nature of a priori intuitions. During the expositions of time and space, they both are identified as having to be of the a priori. Space, Kant says, has to be a priori (analytic) because it does not have to be understood or known by empirical observations, because it cannot be understood the instance where space is not existent, and finally because space underlies all other (namely a posteriori) intuitions. Time is a priori because it is not empirical, and because it is naturally understood. Both space and time are a priori because they are pure forms of sensible intuitions. Space is external, and underlies intuitions of external appearances (cannot remember what Kant’s general understanding of what specifically appearance is, but this is the way I understand it), and is also a priori for that reason. Time is internal and is itself not a concept, therefore it is a priori for another reason. I am leaving reasons for the a priori nature of space and time out, specifically (I keep continuing to specifically use this word in a specific manner specifically) because I am thinking mostly about analytic a priori, and if it is possible for a priori to be synthetic. If you want a more detailed guide to the transcendental aesthetic in its entirety go here:  http://userpages.bright.net/~jclarke/kant/element1.html This link is of a website that contains a huge outline of the entire Critique of Pure Reason, and the link above is just an outline to the transcendental aesthetic. This is a great resource for anyone reading the book or its parts. I do not understand Kant or any other philosopher sometimes, and need a guide.

Having gone deep into space and time and why they are a priori, I have not even defined a priori, so I apologize to those who do not know Kant’s work, or a priori vs. a posteriori intuitions at a all. Before even going into a priori, like Locke, Wittgenstein, Hume, and Berkeley (I think?? haven’t read a whole lot of Berkeley), Kant has a chain or system of how ideas get into being a concept. Sensibility is “the capacity to obtain representations through the way in which we are affected by objects.” Sensibility is the capacity to gain ideas and perception (a not word not used here by Kant, so I apologize for loving that word) from what we see in objects. “Objects are given to us by means of our sensibility.” “Sensibility alone supplies us with intuitions. These intuitions are thought through the understanding, and from the understanding there arise concepts.”  So sensibility gives us intuitions, and with our understanding we build those up into concepts. Appearance by Kant is “the undetermined object of an empirical intuition.” This gives you a general foundation for how Kant views our ideas, or namely intuitions, and how we get them.

Thinking about intuitions (between sensibility and concepts), an a priori intuition is one that can be had without empirical observation. A priori, I think is a hard thing to grasp. When one does not empirically observe things, that person must be in pre-infancy, where there is an intuitive sensible mind, yet empirical observations because of surroundings and stage in brain development cannot be intuited. When thinking about a priori, I think of a thinking pre-infant person in the womb. Returning to Kant’s expositions of space and time, I think a pre-infant would have some notion of space and time. If, for some reason, the placenta was cut off from the pre-infant for even an infinitesimal amount of time, and was not fed, I think it would recognize that it has been awhile since it was nourished with what it is normally nourished with. Space, I think, is not something directly intuited by a pre-infant, but it is something granted, just like time is granted by it in most other occasions besides the one just mentioned.  Besides space and time, I cannot think of anything a priori. A priori is probably intuitions that are barely intuitions and are things we take for granted without taking into consideration. That brings me into the distinction between things analytic and synthetic.

Analytic intuitions (or ideas, or thoughts) I describe as the snap of a finger. Something being understood without having to go through logical process to understand it. Analytic intuitions are granted without much need of verification or clarification. The analytic I like to compare to Bertrand Russell’s hard data in that hard data involves logically primitive and psychologically primitive thoughts. Hard data is solidified into one’s reason where no psychological or logical process of understanding. verification, or clarification is needed. The analytic is logically primitive and psychologically primitive to speak in Russell’s terms.

Synthetic intuitions are those that require the said logical and/or psychological processes of understanding, verification, and clarification to be had. Bringing Russell in to the discussion again, his definition of soft data I think corresponds the the synthetic. Soft data for Russell is logically primitive intuitions, and psychologically derivative intuitions, where one again has to go through many processes to intuit the data. The synthetic, I think is different from soft data in that I think there are some things logically derivative in synthetic that are not automatically granted.  In any sense, the synthetic is unlike the analytic in that many processes must take place to understand it. The analytic requires none of those to be understood simply because analytic intuitions are understood in the snap of 2 fingers.

Knowing what a priori (forgot to say that a posteriori are intuitions that come about by empirical observation, but it matters not, since a posteriori is not the issue to be discussed in my case), analytic and synthetic are, we can discuss a priori together with analytic and synthetic. Analytic a priori is thought by most to be the only a priori. Referring back to the status of a pre-infant where time and space are intuited a priori. Time is analytic because no process is needed to understand it and other intuitions can be built on top of it during the possibility of a posteriori intuitions. Space is analytic because no process (logical or psychological) is needed to understand and grant it immediately. Just think about it right now: can you describe, exemplify, or even think about any synthetic a priori intuitions?

Kant discusses several arguments for synthetic a priori, but when really thinking about it, I cannot justify a synthetic a priori.  Many have thought about this, and most other conclusions are the same. There is no synthetic a priori. A synthetic intuition, needing the processes of verification clarification and understanding to fully grasp it and its intentions, cannot really take place without some kind of empirical intuition. A priori leaves one with only foundations of full concepts, and with only the foundations, a logical, psychological, verificatory, clarificatory, or understanding process cannot take place. For any intuition to be synthetic, it must have some empirical observation or appearance to deal with, and to possibly build up to concepts. Therefore, the only synthetic intuitions are a posteriori intuitions.

This has been said an infinite amount of times. This writing was me just explaining the transcendental aesthetic to myself and any other readers for my/your personal benefit. I just was throwing around some ideas to think about the distinction between a posteriori and a priori.

Thanks for the support as always.

David Lewis’s On the Plurality of Worlds: A Modal Realism

26 Oct

A huge thing that philosophy is occupied by is sense data. Sense data (by Royce, Moore and Russell at first) has its characteristics and are data that come from our perceptive senses. The real question is, concerning sense data: Are the sense data representatives of material objects in reality,  or are sense data just images our minds produce with no relation to reality, therefore sense data having no connection to material reality? When I look at a blue cup,  is there really a blue cup there made of plastic particles fusing together to make a good device to carry a drink of choice, or is the blue cup just something that my mind is telling me is there? Many philosophies advocate one or the other, in different variations, such as solipsists believing that if a blue cup is seen, its existence is not known, extremes are taken, when at the same time, philosophies are less extreme. Considering Descartes, an evil deceiver distorts our visual world deceiving us of certain existences, which is another theory on the matter. Realism theories advocate that what we see pertains to real material existences. David Lewis proposing a thesis for the plurality of worlds advocated a modal realism.

Lewis, a philosopher I have only recently encountered the writing of, begins On the Plurality of Worlds by stating his thesis of plurality. He introduces a modal realism stating that all things perceived and sensed are existent and real in some way. The world I see right now with a computer, a blue cup, an iPod touch, my phone, a bunch of books, the blue sky, and everything else is one specific world. If one were to perceive a world where all life has been demolished except that person, that is yet another world. Some people humorously talk about parallel universes, like if I have blonde hair, blue eyes and am white, my parallel universe world would involve me with black hair, brown eyes, and black, and where everything else is opposite the way things are in the first world.

If one can perceive it, it is a possible world. Lewis puts it very well: “The worlds are many and varied. There are enough of them to afford worlds where (roughly speaking) I finish on schedule [his book], or I write on behalf of impossibilia, or I do not exist, or there are no people at all, or the physical constants do not permit life, or totally different laws govern the doings of alien particles with alien properties. There are so many other worlds, in fact, that absolutely every way that a world could possibly be is a way that some world is” (Lewis). He discusses in the beginning writing his book on time, and refers that to a certain possible world. Also, he states that he writes on the possibilities, not the impossibilities (impossibilia), but in some world he may be writing about the impossibilia. The bold writing says it all.

Lewis also adds that possible worlds perceived do not include worlds we make up. We may make worlds up in sleep, insomniac hallucinations, or narcotic hallucinations, and those are not the possible worlds because those are exaggerations and digressions of ideas of actual material things.

What do these possible worlds mean? To one that believes in this modal realism, it means (in my opinion, and others’) that sense data, or perceptions, denote material objects and/or reality in one way or another. Seeing the regular world one always sees, and then immediately seeing a world where all civilizations are wiped out, are both different worlds, meaning both are reality in one way or another. This is one answer for the argument stated at the very beginning ( are sense data representations of reality, or are sense data just images of the mind not connected to any reality). Modal realism states that all perceptions (not dreamed or hallucinated) are reality and can be of material objects.

So, one might ask, if I am perceiving one world (where monkeys run the world, and humans are the pets), how is the opposite world (where humans are the runners of the world, and monkeys are wild animals or pets) a real world at all? What we are perceiving at one instance is the only world actualized ( the succeeded form of a potential world). Another person besides me might be perceiving the same world, and maybe that person is perceiving a world not actualized to me. Because our perceptions are so different each person’s world is one world actualized while all the other possible worlds are, yet are in a potential state. The actualized potentialized understanding of all the possible worlds was kind of my understanding of all of this. It is also important to note that all possible worlds are not spatio-temporally connected. One world does not appear at one time, and another at a later time. One world does not exist in one space, and another world 6999 light years away. Spatio-temporal connections of the possible worlds are not existent.

To sum up the possible worlds in  modal realism:

  • Worlds are not created by people- As in, one dreaming or hallucinating a round square (how that would be I have not a clue) is not of a possible world because this thing is not at all possible in any world.
  • Worlds are not spatio-temporally connected-  Worlds are not spaced out in time, and are not located individually in space
  • To conclude from the above, worlds appearing to each person (not dreamed or hallucinated) are worlds that happen to be actualized. All  other possible worlds not appearing to a person are potential, and still are.

To discuss more the argument that all perceptions are perceptions of reality, if one saw any blue animal ( a lion for instance)  in one world appearing to him, what that person is seeing would be real. This is because an animal can become blue if it needed to be (not in this case by itself, specifically if this was a weird world where people soaked animals in pools full of blue dye), and this is a possible world. Because of how this is incredibly possible, it is real.  If we try to take something incredibly outrageous and crazy from a dream or hallucination, like seeing a round square, a round square is not real or possible. A round square could not appear in a possible world, and is therefore not real or material in any way (something being real usually denotes it being a material object of some sort). A round square is just an example for outrageous crazy things that we make up sometimes that are not real even in the huge possible worlds of modal realism.

Look around. If you see something that cannot be logically possible then question the reality of your perceptions. But if you look around and cannot find one impossibility to be questioned, then your perceptions are real and material in the best sense of the words.

Thanks for the support, once again.
