A philosopher trying to understand the meaning of life was walking along a beach.
He came across his four year-old son, who was scooping up water from the ocean and pouring it into a sand cup he had constructed.
The philosopher was amused and asked his son what he was doing.
"I'm trying to put the ocean in my cup."
"But you can't succeed," his father objected. "The ocean is much too big for your little sand cup."
And the boy replied "Well, the meaning of life is much too big for your brain, yet you don't stop trying to figure it out."
