Hmm.
Guys, I'd like you to know, when you're depressed it's very difficult to say everything right. Unfortunately I don't understand everything you write back, but I am in a better frame of mind to reply.
There seem to be many clever people including important scientists among the philosophy crowd. There isn't anything wrong with them. My gripe is merely that they tend to use the same techniques to criticise theories that they use to construct them. I get frustrated by how confused it's possible for me to get analysing their logic!
IMO those who think Philosophy is futile simply can't or won't take the time to understand it.
I've tried honest! I still study it at school, and it's quite fun if you see the funny side of it - we study the "analysis of the critique of the major criticisms of the arguments against the theory"!
Does your hatred of philosophy include Christian philosophers?
Well, my hatred for philosophy does not necessarily mean I hate the philosophers. I try not to treat the theories of Christians differently from the athiests, so I still find logical errors in them. I have quite a bit of respect for Thomas Aquinas, and I know how important he is for Catholics. It's just that when you think that his five ways were pretty much identical and try to apply worldly laws (those derived from observation) to God and such, one has to wonder if that's a valid assumption!
(i.e. cause-effect, must be necessary first cause = God, maximisation on the scale of morality = God, etc.)
Never mind though. I've found what I've been searching for. There is a philosophical theory that there is no fundamental basis for knowledge. This seemingly destroys all the achievements of philosophy and of the theory itself! I'm satisfied that philosophy has become as rediculous as I had thought.
As for whether philosophy is futile, well it depends on your definition. Many here have argued that rationality and logic are important, a view with which I agree. But since many philosophers make such liberal mistakes in their theories, I have to say that my view of the profession of philosophy as a whole is quite low.
However, side tracking a little, an interesting thing to bear in mind is that I as a lowly philosophy student may not have the logical capacity to be qualified to criticise them. Any theory has it's limits, since we're all human. And Wittgenstein's anti-realism states that it only means as much as people subjectively interpret from it in the same community. Maybe I'm just interpreting it all wrong. After all, that seems a simple conclusion to an otherwise large problem.
Meh.

I scare myself sometimes.
