Ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science.Charles Darwin
Forgive me my nonsense, as I also forgive the nonsense of those that think they talk sense.Robert Frost
Things on a very small scale behave like nothing that you have any direct experience about. They do not behave like waves, they do not behave like particles, they do not behave like clouds, or billiard balls, or weights on springs, or like anything that you have ever seen.Richard Feynman
I am humble Abraham Lincoln. I have been solicited by my friends to become a candidate for the Legislature. My politics are short and sweet, like the old woman's dance.Abraham Lincoln
I don't have much positive to say about motor neurone disease. But it taught me not to pity myself because others were worse off, and to get on with what I could still do.Stephen Hawking

This attitude of mind - this attitude of uncertainty - is vital to the scientist, and it is this attitude of mind which the student must first acquire.Richard Feynman
We would frequently be ashamed of our good deeds if people saw all of the motives that produced them.Francois de La Rochefoucauld
When power leads man toward arrogance, poetry reminds him of his limitations. When power narrows the area of man's concern, poetry reminds him of the richness and diversity of existence. When power corrupts, poetry cleanses.John F. Kennedy
