It is unwise to make education too cheap. If everything is provided freely, there is a tendency to put no value on anything. Education must always have a certain price on it; even as the very process of learning itself must always require individual effort and initiative.

Any man can learn anything he will, but no man can teach except to those who want to learn.

The greatest education in the world is watching the masters at work.

Study without desire spoils the memory, and it retains nothing that it takes in.
