G. Stanley Hall quotes:

Adolescence is a new birth, for the higher and more completely human traits are now born.

Abundance and vigor of automatic movements are desirable, and even a considerable degree of restlessness is a good sign in young children.

The man of the future may, and even must, do things impossible in the past and acquire new motor variations not given by heredity.

Of all work-schools, a good farm is probably the best for motor development.

Adolescence as the time when an individual 'recapitulates' the savage stage of the race's past.

Every theory of love, from Plato down, teaches that each individual loves in the other sex what he lacks in himself.

Civilization is so hard on the body that some have called it a disease, despite the arts that keep puny bodies alive to a greater average age, and our greater protection from contagious and germ diseases.

This splendid subject [mathematics], queen of all exact sciences, and the ideal and norm of all careful thinking...

Precisely what menstruation is, is not yet very well known.

Muscles are in a most intimate and peculiar sense the organs of the will.

The years from about eight to twelve constitute a unique period of human life.

Normal children often pass through stages of passionate cruelty, laziness, lying and thievery.

.. every step of the upward way is strewn with wreckage of body, mind, and morals.

Adolescence as the time when an individual "?recapitulates' the savage stage of the race's past.

Adolescence is when the very worst and best impulses in the human soul struggle against each other for possession.

Every theory of love, from Plato down teaches that each individual loves in the other sex what he lacks in himself.

Oneness with Nature is the glory of childhood; oneness with childhood is the glory of the Teacher.

The teens are emotionally unstable and pathic. It is a natural impulse to experience hot and perfervid psychic states, and it is characterized by emotionalism. We see here the instability and fluctuations now so characteristic. The emotions develop by contrast and reaction into the opposite.

There is no more wild, free, vigorous growth of the forest, but everything is in pots or rows like a rococo garden... The pupil is in the age of spontaneous variation which at no period of life is so great. He does not want a standardized, overpeptonized mental diet. It palls on his appetite.

All possible truth is practical. To ask whether our conception of chair or table corresponds to the real chair or table apart from the uses to which they may be put, is as utterly meaningless and vain as to inquire whether a musical tone is red or yellow. No other conceivable relation than this between ideas and things can exist. The unknowable is what I cannot react upon. The active part of our nature is not only an essential part of cognition itself, but it always has a voice in determining what shall be believed and what rejected.

Modern man was not meant to do his best work before forty but is by nature, and is becoming more so, an afternoon and evening worker.

Muscles are in a most intimate and peculiar sense the organs of the will. They have built all the roads, cities and machines in the world, written all the books, spoken all the words, and, in fact done everything that man has accomplished with matter. Character might be a sense defined as a plexus of motor habits.
