The ideals which have always shone before me and filled me with joy are goodness, beauty, and truth.

Unthinking respect for authority is the greatest enemy of truth.

If most of us are ashamed of shabby clothes and shoddy furniture, let us be more ashamed of shabby ideas and shoddy philosophies... It would be a sad situation if the wrapper were better than the meat wrapped inside it.

I have never looked upon ease and happiness as ends in themselves - such an ethical basis I call more proper for a herd of swine. The ideals which have lighted me on my way and time after time given me new courage to face life cheerfully, have been Truth, Goodness, and Beauty.

You ask me if I keep a notebook to record my great ideas. I've only ever had one.

Pure mathematics is, in its way, the poetry of logical ideas.
