There are many things which we do not understand, both collectively and as individuals. Learning is the process of discovering that there is even more which we do not understand.

I disagree with Webster on this issue. Learning is not the act of obtaining knowledge. Learning is interpreting knowledge and transforming it into wisdom. You may seek all the knowledge you wish during the course of your life, but you are only truly learning if you seek knowledge in order to be humbled by it.

Please forgive me if I come across as preachy. Behind the universe is numbers, but be aware of something behind the numbers.
