Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric.
I believe in using words, not fists. I believe in my outrage knowing people are living in boxes on the street. I believe in honesty. I believe in a good time. I believe in good food. I believe in sex.
I think we ought always to entertain our opinions with some measure of doubt. I shouldn't wish people dogmatically to believe any philosophy, not even mine.
I would never die for my beliefs because I might be wrong.

The trouble with the world is that the stupid are cocksure and the intelligent are full of doubt.
The world is full of magical things patiently waiting for our wits to grow sharper.
There is much pleasure to be gained from useless knowledge.
What is wanted is not the will to believe, but the will to find out, which is the exact opposite.
