From one of my favorite purveyors of the human condition, Seth Godin:

Magic and irrational

"Today is Pi day, the 14th day of the 3rd month of the fifteenth year... 3.1415

Pi is our most famous irrational number. Not irrational in the sense that it's a foolish argument, a form of wishing for one thing while doing another. No, pi is irrational in a magical, beautiful sense. It can't be cropped off and fit into a box. The closer you look at pi, the more you see, forever....

To be transcendent and irrational is to always have a few more digits to spare, to demand that you not be rounded off and filed away. To be human."
