As you know, Sean, I have lost the ability to initiate posts here since you've shut off the Yahoo membership mechanism. As a result, I typically respond to posts but do not initiate them here. However, I ran across two very amusing on-line animated videos today which place some of Wittgenstein's actual words into the mechanized mouths of robotic animations. The result is hilarious and I decided to send it on to some family and friends via e-mail. However, it occurred to me that they might not appreciate it, lacking a background in Wittgenstein and philosophy. So I set about explaining it to them. Before I'd finished I had a virtual mini-treatise on the differences between the early and later Wittgenstein. After paring it back somewhat, I sent it on. But it occurs to me that it might be worth posting here to see what some Wittgensteinophiles on this list have to say about it. Perhaps I got some things wrong or perhaps others here will have other useful notions to add by way of additional commentary. So without further ado, here it is (I hope the links to the videos prove useable). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ (Addressees Deleted) What the guy who made the first video here has done is put Wittgenstein's foreword to his Tractatus in the mouth of a stuffy animated character. Listening to the words (instead of reading them as they were meant to be approached) actually turns out to be hysterical. I couldn't stop laughing: http://www.youtube.com/watch?v=uljz2PeqWwc&feature=related Of course, we know that Wittgenstein, years after he wrote it, actually rejected his Tractatus, announcing in his foreword to his later book, the Philosophical Investigations, that the author of the Tractatus had made some grave mistakes. Maybe he'd have come to that conclusion sooner if he'd had a chance to see this YouTube animation of what he was trying to say first! The animation that follows is of one small section from that later work, Philosophical Investigations. Of course, it sounds just as absurd -- but in this one it's because the video maker gives us only a fragment, taken completely out of its context. Still, it's pretty funny, too: http://www.youtube.com/watch?v=FCh8fhG94O4&feature=related Here, though, is the context which, when seen, I think will show why Wittgenstein is an important thinker: He was discussing why it makes no sense to suppose that solipsism -- the idea that the only thing that's real is ourselves -- is true. The Problem For centuries philosophers have agonized and argued over how we can know what we know. How can we be sure we are not just the victim of some giant delusion? This is the knowledge or epistemological problem. Whole theories and arguments have been developed and elaborated in Western philosophy to justify our knowledge, to demonstrate that we really do and can know things. Of course you can argue that common sense already tells us this. But the problem is that common sense, being just another claim of knowledge, could itself be part of the delusion. Philosophers have thus struggled to provide a solid basis for knowledge claims in light of the fact that everything we know seems to be supported by such basic beliefs about the world as solipsism seems to throw into question. Wittgenstein's "Solution" His point in the larger text from which the second video clip is extracted boils down to the claim that to express ideas we must do so in language and language is ultimately a public, not a private, matter, i.e., it is shared with other language speakers. Language he proposes, is a matter of learning the rules for how to use words and then following those rules correctly. But, he points out, there can't be any rules unless there is a standard outside of ourselves against which to measure the rightness or the wrongness of our uses. Therefore, as soon as we try to claim that solipsism is true we are also, in effect, denying that truth because, to say it's true is to use language which assumes that others are already present (because language cannot be private, i.e., you need a community of language speakers to have and follow rules). If others ARE present, then, of course, solipsism can't be true (because solipsism implies that there is no one else but ourselves to be present). This was actually an ingenious (if still somewhat controversial) solution to the age old philosophical problem of how we can be sure we know anything about an external world. Solipsism and similar forms of radical skepticism are not, on this view, false anymore than they are true! They are simply unintelligible claims that cannot even be stated coherently let alone questioned. Wittgenstein's Broad View This ties into his larger point that "problems" like this (the meat and potatoes of classical philosophy) are not substantive problems at all but only the result of our getting confused in how we use language. We think that asking questions like "How do I know there is an external world?" or "How do I know there are others in the world besides me?" can be answered intelligibly with some kind of "because" reply, by giving some reasons we take to be inarguable (and which we hope to prove are inarguable). All sorts of theories of knowledge and the world are thus devised by philosophers in order to provide a basis for our common sense beliefs. But in fact, as the later Wittgenstein showed, the very question that underlies this challenge is unintelligible. And, if it is, it cannot even be asked and, if it can't, then it also cannot be answered. So it's not a question of whether it's true or false after all. Non-solipsism and related forms of radical skepticism are simply excluded from consideration because they don't depend on reasoning but are already built into what we are, what he called our "form of life". The Difference Between the Early and Later Wittgenstein Initially he was in the thrall of these very kinds of problems and struggled to find an acceptable answer, as other philosophers did. The Tractatus, his first book, attempts to do this by describing how language relates to the world, how language consists of certain pictorial and logical relations and that, once you understand these, you know what you can say and what you can't (what can be pictured via these logical relations and what can't). Then questions like whether solipsism is true, say, are seen to be beyond clear statement within language (because solipsistic statements and the like lack adequate referents in the world -- they don't point to or name anything we can discover in our experience). He therefore placed such questions outside the zone of rational discourse. But he still allowed their significance, albeit, he thought, in some deeper, non-linguistic way. Such statements were nonsense in the sense of being inexpressible in any but some poetic way, but they were still important -- perhaps more so than the statements we could make about the world which had sense (i.e., genuine referential relations). But the later Wittgenstein concluded that this was a mistake. It wasn't that such statements involved some great mystery beyond the realm of rational thought, accessible only in some mystical way (i.e., what we can "show" but cannot "say"). Rather it was that language, itself, confuses us at times (especially when it comes to philosophizing). Once we realize that this confusion stems from a failure to recognize that we're using language incorrectly (in the present case of solipsism, for instance, we had been thinking that there was a legitimate question to raise when there wasn't), the problem that had troubled us seems to simply dissolve away. In other words, such issues are more like puzzles than real problems and their solutions involve unpacking them so that they cease to puzzle us, rather than looking for an answer in terms of a logical proof or some kind of convincing evidence in favor of our claim. At the heart of the change lies Wittgenstein's changed view of language although in both the Tractatus and the later book, language is what he homes in on. I wanted to explain this because I know most of you have a hard time figuring out what Wittgenstein is about when I mention him, why I find his work interesting and why any of it matters to anyone but me!
