You make a great, very great mistake, if you think that psychology, being the science of the mind's laws, is something from which you can deduce definite programmes and schemes and methods of instruction for immediate schoolroom use.

You perceive now, my friends, what your general or abstract duty is as teachers. Although you have to generate in your pupils a large stock of ideas, any one of which may be inhibitory, yet you must also see to it that no habitual hesitancy or paralysis of the will ensues, and that the pupil still retains his power of vigorous action.

An impression which simply flows in at the pupil's eyes or ears and in no way modifies his active life, is an impression gone to waste. It is physiologically incomplete... Its motor consequences are what clinch it.
