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

“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”

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

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

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