how the hell ?

• In the article, the text is: "...what does it mean to say that this particular apple is a copy of the form of applehood? Does it mean the apple is the same shape as the form? Probably not; the form, after all, is not supposed to have a shape because it is not spatial. What would it mean to say that apple participates in applehood? Is that like membership in a club, somehow? It is not clear."
  • I'm trying to relate Forms to sets. Would it be correct to say that an apple is one of the set of apples, and that the Form of apples is the same as the set of apples? Or would it be more correct to say that the Form of apples is the set of criteria that determine whether an object properly belongs to the set? Alan Nicoll 19:07, Feb 4, 2005 (UTC)

It's difficult to answer your question, because it depends on the meaning of the word "set". If with the "set of X" we mean some factual aggregate of material objects, this is certainly not the interpretation of "Form" by the Platonic Realist himself. But some would say it's the only rational content that could be given to an otherwise inane concept. The Platonist, and certainly the modern one, would surely agree more with your second description, that it's a set of criteria. But he would warn against the mistake to again see such a set of criteria as some factual aggregate of actual ideas in the minds of actual people (which despicable heresy goes under the name of mentalism) or of actual social rules in an actual society (sociologism,conventionalism). The set of criteria should in his view be seen as an abstraction; indeed an abstraction that is more fundamental to the concept of set than the respective aggregates of material objects - and so he would say that the Form of an apple is indeed the set of apples: in abstracto.

It depends on what you mean by "criteria", but Platonic Forms cannot be sets of objects, by my lights. That is because sets are extensional entities - two sets are identical if and only if they have the same members. But if, for all pairs of non-synonymous predicates (or properties), there are two corresponding Forms, we have two Forms even when the predicates are extensionally equivalent (true of the same things). But we cannot have two Forms for two extensionally equivalent sets, because extensionally equivalent sets are the same set, and (I think) there is at most one Form per object (or property).

[edit] Aristotelian realism

It would be nice if the same author wrote an article on Aristotelian realism to contrast with the Platonic variety, esp. as there are already articles on conceptualism and nominalism. The possibility of realism about the abstract without a commitment to Platonism is an intringuing one.

That would be very nice indeed as that writer is Larry Sanger, a professional philosopher and cofounder of Wikipedia! :o) But the subject is extraordinarily controversial and complicated. Part of the problem is that Aristotle's public works have been all but lost — we today "only" have the Corpus and there are many uncertainties about authorship and date of creation. But even more problematic is that Aristotle developed his thoughts in opposition to Platonic Realism: so to judge his thought we have to understand the nature of Plato's as well.

Here is the basic form defined. A driveway is the subject and all kinds appear as generalized driveways. This abstract driveway is then the subject and to cause the set than.

"And to cause the set than" denotes Plato's form. A twice thought for the abstract. And the abstract abstraction is the level of difficulty. To abstract all that is, correctly, identifies a form of natural existence. Just like left and right as an existent relation, Plato's form denotes a subject abstraction and clearly becomes a class of inference.

I can write all day on this subject if there is any interest.

A subject of forms therefore denotes a relation of the abstraction to the particular set. A sly thought is the degree of confusion over the meaning of his form. A kind of inference appears!

[edit] Articles on Platonism

Note that this article more or less competes with Platonic idealism, and that there is a whole raft of articles on Platonism, which perhaps ought to be consolidated into fewer. A Platonism template might also be useful. --HK 14:42, 29 January 2006 (UTC)

This is what I said at Talk:Platonic idealism:

1. Although Platonic Realism is indeed sometimes called Platonic Idealism, the concepts are not congruent. Many would deny that Plato's idealism entailed a realist stance. And Platonic Realism is a more general philosophical position, while "Platonic Idealism" is typically reserved for the views of Plato himself. It's therefore best to keep two articles.
2. Some repetition is inevitable and often a lot of repetition is quite functional.
3. If there are any perceived contradictions, try to solve them. But be wary. Sometimes they are merely perceived :o).
4. A Platonism template would be very nice of course.
5. Wikipedia should be in a permanent state of improvement. Try to fight the understandable but ultimately disastrous tendency to "consolidate". Or was it a euphemism for "merge"?

What you say here at least answers my question :o). I'd like to add that Platonism is a very interesting and complicated subject, that can be treated from many subtly different aspects. A "raft of articles" wouldn't be amiss.--MWAK 16:04, 29 January 2006 (UTC)

[edit] Plato is bullshit

I dont expect to be able to put this in the main article, so it is here for your consideration. He is one of the first thinkers and does not deserve more than anecdotal consideration, his ideas are hilarious to a modern man. Granted we must treat him with respect, but dont let that trick you into thinking that he has any meaningfull thing to say in the 21st century. 88.15.59.243 23:17, 17 October 2006 (UTC)

And you would be the epitomal "21 century-Man", I suppose? ;o) Any evaluation of Plato of course depends on your philosophical opinion. These opinions today vary wildly. I've often noticed that people changed their views on him after actually reading his work, instead of relying on largely anecdotal renderings of it... And there is always the troubling possibility that you only consider some ideas to be hilarious as a defensive reaction, because you despair of being able to understand them. --MWAK 08:46, 18 October 2006 (UTC)

[edit] Analogies to Computer Science/Object oriented Programming

The language for much of the article talks about 'instantiations', inherence, forms, etc... Sounds very much like inheritance/etc... from computer science. Perhaps this is deliberate, perhaps written by a comp. sci. person, perhaps it's totally my perception. —The preceding unsigned comment was added by 128.100.71.61 (talk) 13:51, 20 March 2007 (UTC).

The jargon used is very much standard and rather a bit older than computer science. So if there is indeed a causal connection, philosophy is the origin :o). --MWAK 14:50, 20 March 2007 (UTC)
