"Some books are to be tasted, others to be swallowed, and some few to be chewed and digested,"

It is not what is read or what is remembered, but only what is understood, that gives power,

"He who knows not, and knows not that he knows not, is a fool; shun him.
He who knows not, and knows that he knows not, is a child; teach him.
He who knows, and knows not that he knows, is asleep; wake him.
He who knows, and knows that he knows, is wise; follow him."
