I cannot stop questioning philosophical issues. I have delved deeply into both sides of many of the main debates and of course come out with no new answers. Everything is subject to doubt. Can you ever really know anything? If not...is it possible to give life any meaning? How can you live life to the fullest if you cannot stop questioning? How can you not question things/Does anyone else feel this way?
My username is Athenian. What do people usually associate ancient Athens with?

In short, yes, someone else feels this way. Many have, and many do, in fact.
I don't believe it's possible to know the world, but I do believe it's possible to know ourselves to some degree. We can know what is right for us, and we can constantly improve our ability to make valid assumptions.
I actually believe that it's the lack of knowledge that gives life meaning. I think If we actually KNEW something, we would no longer be curious about it, and it would become meaningless. It's the very fact that it's an argument, that it's not known for certain, that gives it meaning.
I think that questioning is what life is all about, thus in the very process of questioning and exploring/modifying our sense of knowledge, we ARE living life to the fullest. In other words, the meaning is in the questions, not the answers.
That's my take, anyway.
