John Keats

"at once it struck me what quality went to form a Man of Achievement, especially in Literature, and which Shakespeare possessed so enormously - I mean Negative Capability, that is, when a man is capable of being in uncertainties, mysteries, doubts, without any irritable reaching after fact and reason"

Do you not see how necessary a world of pains and troubles is to school an intelligence and make it a soul?

My imagination is a monastery and I am its monk.

Nothing ever becomes real till it is experienced; even a proverb is no proverb to you till your life has illustrated it.

The only means of strengthening one's intellect is to make up one's mind about nothing, to let the mind be a thoroughfare for all thoughts.
