Imagination is more important than knowledge.

Information is not knowledge.

There comes a time when the mind takes a higher plane of knowledge but can never prove how it got there.

All sciences are vain and full of errors that are not born of Experience, the mother of all Knowledge.

Nothing is so well learned as that which is discovered.

One whose knowledge is confined to books and whose wealth is in the possession of others, can use neither his knowledge nor wealth when the need for them arises.
