I think you guys are both missing the point. When we go through life we always reach a level and think to ourselves, "Wow, I know a lot now, and I don't believe in all the same things I did 1, 2, or 5 years ago". And that happens constantly in our life. Sometime we go back to old beliefs and we often keep moving forward. The point being it is contradictory to the learning process and to those realizations to actually pin down a point where you think you've got it all, because you never do and never will.
