"To prejudge other men's notions before we have looked into them is not to show their darkness but to put out our own eye" — John Locke

Small minds are concerned with the extraordinary, great minds with the ordinary

Nine-tenths of wisdom is being wise in time

Willpower is to the mind like a strong blind man who carries on his shoulders a lame man who can see

There is a wisdom of the head, and a wisdom of the heart.

The mind is not a vessel to be filled but a fire to be kindled

I must have a prodigious quantity of mind; it takes me as much as a week sometimes to make it up
