Exactly, it's all just hippie jibberish in the end. It might be a good topic to discuss if I were hanging around with the "Dazed and Confused" crowd, but I don't.
Philosophy for the most part is just theory that negates science. Sure the cells of George Bush aren't the same, but in the end everything is carbon based. The formation of molecules forms a complex organism capable of thought. One of those organisms thought of the idea of making a college class about "what ifs" and then that brings us back to where we started.
I don't mean this to be rude towards anyone in the least way. I just take a much more scientific approach to life. It might explain why I'm not religious.
