I've learned everything I know. Duh.
Really, I have though. That question is a very vague one, considering that my answer is most likely true for all people. We've learned what we know, and without that, we know nothing. Our knowledge is like the Tower of Babel, reaching up to the heavens as we accumulate more and more bricks of understanding. However, knowledge can also be your downfall, as illustrated in this case. The people of Babel were provoking God to jealousy of his position, and so he struck them down. And so we can be destroyed by our own knowledge, lest we find out something our minds are not equipped to know. Then, we wither away and ironically become insane, aware of nothing at all and yet slowly being killed by the stark realities we used to wake up to everyday, blissfully unaware of what was happening right before our very eyes.
That being said, I'm agnostic, so I just used the Tower of Babel as an example. I also love gathering knowledge, contrary to what may have been implied above- I just placed myself into a different perspective and wanted to see what I would say when thinking in this manner. I do like to impersonate other points of views on specific subjects, especially if that point of view is as credible as my own- indeed, I often contradict myself in arguments, frequently looking at both sides of the debate and bringing in facts that are as much my self-destruct as theirs (destruction). I can't help it, it's as much a part of me as logical reasoning is, as a matter of fact, deriving from that system itself.
I have gotten off-topic yet again, not to mention posting in a thread that's been inactive for months. Whoops, maybe I should stop that- I did it in another forum too. I feel the need to say sorry, although I don't know what for.
