Philosophy is asking questions about the nature of reality. Religion and science are both offshoots of this, and are, for the most part, accepted (though not necessarily at the same time) by most people. Which is why it confuses me that people think philosophy makes no sense. There were a lot of things that had no answers in the past. People asked the questions, talked about it, and got the answers. And if they were wrong answers, they talked about it some more til they figured out the right ones. That's what philosophy is, a quest for answers. Just because we don't know the answers now doesn't mean that we won't ever know them. Some of them are pretty tough questions, but who knows, maybe in future we'll all know exactly what reality is and what we're here for. And if we do, it's because we asked the questions, reasoned it out, and came to a conclusion. Philosophy is the art of asking questions. That's all.
