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.

Daily contact with some teachers is itself all-sided ethical education for the child without a spoken precept.

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

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.

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.
