obtruding their morbidness upon it they batter down its
resistances and lower the thinking power.

Though we can never know the history of man's origin, the lives
of the child and of the wild man help us to understand
something of the order of racial development. All the higher
mental faculties grow in the child as they grew in the
race--out of impulse, instinct, feeling; and from infancy to
maturity we recapitulate mentally and physically the early
human-making stages, short circuiting in twenty years the
race-process.

The life of physical activity that the child leads develops and
coordinates the brain and the muscular system. In this way the
great motor functions are organized in the brain and become
part of the physical basis of mind.

The older education that trained the intellect exclusively,
without reference to the practical demands of life or the needs
of the body, was inadequate in that it ignored the law of

Stanley Hall says "we think in terms of muscular movement," and
this expresses the most important single fact in the mature

muscular movements is basic in development.

The muscles are the special organs of volition, the one part of
