"This people draweth nigh unto me with their mouth, and honoureth me with their lips; but their heart is far from me." Tell the teacher that the function of education is to foster growth; that therefore it is his business to develop the latent faculties of his pupils; and that therefore (since growth presupposes exercise) he must allow his pupils to do as much as possible by and for themselves,--place these propositions before him, and the chances are that he will say "Amen" to them.

But that lip assent will count for nothing.

One's life is governed by instinct rather than logic.

To give a lip assent to the logical inferences from an accepted principle is one thing.

To give a _real_ assent to the essential truth that underlies and animates the principle is another.
