A very wise old teacher once said: I consider a day's teaching wasted if we do not all have one hearty laugh.

Bad teaching wastes a great deal of effort, and spoils many lives which might have been full of energy and happiness.

The young do not demand omniscience. They know it is unattainable. They do demand sincerity.

You [the teacher] do not merely insert a lot of facts, if you teach them [the students] properly. It is not like injecting 500 cc. of serum, or administering a year's dose of vitamins.

At certain times and in certain schools it is orthodox to be a rebel; and in general it is a very poor class that does not contain at least three pupils who can be counted on to oppose the teachers authority and loudly and persistently to question everything he says.

Many of the twisted minds and crippled characters in the world were made by careless parents who kept their children away from knives and fires, but put permanent scars on their souls.

Many of the snarly bad-tempered teachers whom we remember with hatred were really nice people soured by years of anxiety and penny-pinching.
