I take it that no man is educated who has never dallied with the thought of suicide.

It is only the fundamental conceptions of psychology which are of real value to a teacher.

As there is no worse lie than a truth misunderstood by those who hear it, so reasonable arguments, challenges to magnanimity, and appeals to sympathy or justice, are folly when we are dealing with human crocodiles and boa-constrictors.

So you see that the process of education, taken in a large way, may be described as nothing but the process of acquiring ideas or conceptions, the best educated mind being the mind which has the largest stock of them, ready to meet the largest possible variety of the emergencies of life. The lack of education means only the failure to have acquired them, and the consequent liability to be 'floored' and 'rattled' in the vicissitudes of experience.

Act the part and you will become the part.

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.

As a rule we disbelieve all the facts and theories for which we have no use.
