Allright, here's how I see it. First, the only thing I can be sure of is that I experience things, so I know that
something exists in order to experience them. Yes, I'd like something more definite than "Cogito, ergo sum" too, but it's the only real starting point we have. I'd prefer to state it as "I
experience, therefore I exist", though, since it's entirely possible to experience the world without "thinking" about it in the usual sense (I''ve done it myself, after a night of no sleep. No, drugs *weren't* involved ;) Although it proves, as much as anything can be proved, that something exists, it does not in itself prove what the nature of that existence really is. However, our experience does have one very interesting property- that of repeatability, and consistency. By which I mean, when I think in a certain way it always makes it appear and "feel" as if my arm is trying to move, and my visual input tells me that if something is not supported by a solid object, it seems to fall downward, etc. I've gotten used to the visual appearance of objects, and how that seems to correlate with the tactile input I get when I seem to "touch" them. These things remain more-or less consistent. If the properties of the universe around me changed at random, it would be rather hard to make even the limited amount of sense that I do out of it. I noticed that there seem to be other beings who look and behave much like my concept of the way I do. We are able to communicate, albeit imperfectly, and from this I learned that they seem to "think" and experience the world in a manner similar to me. In communicating and observing them, I learned that we share common concepts about the repeatable and consistent aspects of reality. Sometimes things happen which contradict my concept of what should have happened, so I either have to adjust my methods of prediction, assume that my methods of prediction were fine but the information I was using them with was inaccurate, or simply ignore the discrepancy (something humans are fairly good at :)
I could go on like this, through the derivations of higher and more abstract concepts like History, Society, even Quantum Physics, and the ways in which the input of our senses can be mitigated through our need to exist in "consensus reality", but I think you get the idea. I (and, I assume tacitly for the moment, the rest of you, since my senses tell me you are similar) experience a world in which certain actions seem to result in certain effects, which allows us to learn.
Now, whether or not that world is "real" I cannot say- perhaps we are all simply aliens lying in pods, dreaming we are humans. Perhaps those aliens are themselves part of some larger dream, and when the totality of existence ceases to exist the words "GAME OVER" will blink over the darkness, just before *something* goes back to its normal life. I cannot know, but what I do know is that at this point the repeatability of cause and effect appear to give us the opportunity to learn more about the universe, whether or not it actually exists. And, in my opinion, that's just what we should do.

I don't believe philosophy is really about discovering "truth", since, even if truth exists, we can never know it. I myself don't believe that truth exists; actually, I believe the very concept of "truth" is meaningless. Philosophers since (at least) Plato have struggled to define truth, and to figure out how we can arrive at truth, but it's gotten us nowhere.
"Truth" is usually defined as the correspondence between "objective reality" and "subjective reality", but both concepts are really meaningless. After all, what we only encounter "objective reality" through our sensory perceptions. What we call objective reality is really just an extrapolation, not necessary in any way, from these perceptions. But our perceptions themselves are really specialized forms of thought in our mind. The perception of a flower is merely a more vivid form of the same sensation we have when we think of a flower. Thus, everything we encounter in "objective reality" is happening in our head. So where exactly is the distinction? It seems to me as if the idea of "objective reality" is a superfluous add-on that's used as an "explanation" for our perceptions, in much the same way that God is a superfluous add-on that's used as an "explanation" for the universe.
Absolute Truth may indeed be impossible to arrive at, or even define properly. Truth within a limited scope, however, is more approachable. Within my own experience, for instance, if I let go of a pen from a height, it falls. This has come true numerous times, and is supported by experienced with other objects that I classify as "similar" according to my senses. So, I could say that, within my own experience, pens fall when dropped. Now, if I were to visit outer space and drop a pen, I would have to modify this to include the idea that pens only drop close to Earth. And so on. I do not believe that absolute Truth can ever be reached, even within a limited scope*. I think of it as being similar to the asymptote of an equation- we can always get closer, but never *quite* reach it. Hofstadter has a nice 2-D analogy of this concept in a more limited setting on page 71 of GEB (although it think it would have worked better had he used an actual fine-grained fractal, rather than relying on his own artistic skills ;) Hopefully, someday humanity will have learned enough to make the current amount of knowledge we possess approach 0 in comparison. Which wouldn't be too hard, really...
* You might think it odd that I would make such a direct statement, when I've been circumspect about things like whether or not the rest of you exist. The reason is that this is such speculative, almost aesthetic territory that I think the qualifiers are implicit (of course, if I thought they were
that implicit I wouldn't be writing this lengthy and now self-referential footnote, would I? I blame having talked about
Don Coyote recently- if you ever read it, you'll understand).

Even if we temporarily assume that an "objective" reality exists, it seems that we could never truly learn ANYTHING about it. We can't even really learn whether there is a good probability that something is or isn't true. For example, I say that there is no invisible pink unicorn in the room with me right now (or, if I'm the cautious scientific type, I say that it's highly unlikely that there's an invisible pink unicorn here[/i]) because of Occam's razor. Occam's razor states that we should only believe in as many entities as are necessary to explain our observations. When you think about it, however, there's no real reason this statement should be true. Hell, there could easily be a whole bunch of things that exist that simply do not effect us in any way. Maybe being able to be perceived, even indirectly, by humans is an exception in the universe rather than a rule. Once you take all this to its logical conclusion, it kind of gets a little silly, and demonstrates that the very concept of the "objective world" is utterly without meaning.
*Ahem* Occam's razor is a scientific rule of thumb. Science concerns itself only with phenomena which are either directly or indirectly observable, or which are implied by observable phenomena. Within this purview, we can indeed "learn" things. I would imagine that you yourself have learned that when your sensory input tells you that you're falling from a height of 10 feet in the air or so, the sensation of pain usually follows. You learn things all the time, one of which being the existence of similar beings to yourself, some of whom, coupled with your own observations, lead you to believe in thing like "gravity" or "India" or "Quantum Physics", even though you may not have experienced them directly. You could be entirely correct in saying that the majority of objects in existence are made of some material which is not in any way observable (and the existence of which is not implied by any phenomena which are). But even if you're right, from the standpoint of Science, they don't exist. It's rather solipsistic of Science to say this, but quite understandable. Scientists have plenty of work trying to explain phenomena that are observable. If they had to explain the infinite set of possible non-existent phenomena as well, they would be a bit swamped, to say the least :) I think most of them are happy to leave the speculation about non-existent entities to science fiction and fantasy writers (unfortunately few of whom take advantage of the fact)

Philosophy is showing how some of our assumptions contradict others, and (somewhat arbitrarily) picking which assumptions to keep and which to lose. At its most fundamental level, it is about creating pictures of reality which are beautiful and elegant (although perhaps not in the normal sense of these words).
Eh, if it's just about aesthetics, I'd put that as a subset of magick. Of course, one might say that Scientists find a world made of consistent rules aesthetically pleasing, and so Science is just another subset of magick ;) (*Squints at Icy* You'd make a decent enough Chaos mage, methinks, if you ever decided to go insane…)

Truth doesn't enter into it. I'd consider philosophy a particular specialized genre in fictional literature.
Ha! Ctrl-C, Ctrl-V. Congratulations, you just made it into my quote file :)

Hey, don't blame me- Icy dragged me into it! Honest! He's Evil™! After I realized that one could get stuck in a quagmire of criticism, meta criticism, meta-meta-criticism, etc., I had to get out. I swear, I don’t usually go around discussing postmodern theorists. *shudder* And that determinism bit probably would have made my quote file, if it wasn't so long (and it I didn't already say much the same thing whenever I'm within 10 ft. of a determinism debate. Apparently, smartasses everywhere think alike… ;)

Heh. Finally saw it, did you? To the

Pah. I just wish I could find a copy of

I have some problems with the Many-Worlds interpretation however. For one thing, it does not sufficiently explain the very thing it was created to explain - that is, Quantum Probability. What exactly does it mean to say that the probability of an atom decaying within a certain period is 75%? How can the world where the atom doesn't decay be more "improbable" than the world where it does? Since there are an infinite number of universes, and dividing infinity by anything other than infinity results in infinity, then no particular universe is less "probable" then another.
See
here. Specifically,
this. That explanation is rather technical (to the point where one might accuse the author of obscuring one of the theories' weak points with specialized jargon), but what it boils down to is that from an observers point of view, the normal statistical rules apply. Which universe you exist in depends on how probable it is. It's late; I'll see if I can make a more complete stab at the manifestation of probability in M-W in the morning…
I'm somewhat partial to the M-W (or Everett, if you prefer) interpretation myself, although I'm not a quantum physicist (yet). It avoids the nasty Solipsistic/Vitalist tendencies inherent in the Copenhagen explanation, for one. Quite frankly, the whole issue of making interpretations of Quantum Mechanics has a slight tendency towards loopyness, given the general weirdness of QM from our point of view to begin with, so it's not too surprising that there are so many objections to the current ones. The Everett interpretation, or some derivative threreof, just seems like the most reasonable one at the moment.
And for good measure,
here's another page, somewhat more critical of M-W.
It's late, so the above post may be somewhat rambling, particularly the first part. I'll have to see if it still makes any sense in the morning…
Extra-useless bonus MOOism links!
I went searching to see if I could possibly find a mention of
Don Coyote in Google's USENET cache, but all I came up with were some old posts I made in the Kibology (a relatively tame absurdist pseudo-religion I tried to assault with the power of MOO) newsgroup that kind of cracked me up (possibly out of nostalgia). Enjoy! Or, more likely, Justifiably Ignore!
I tried, honestly. Some people just won't be helped…
You don't fuck with the MOO. Read carefully, for the full effect. Or full stupidity. Whichever.
