eless, after a while they
get out again "to see if there is anything." These germs are carried
about enclosed like tubercular bacilli in some tiny lymphatic gland;
the whole organism is weak. But the mischief is hidden and causes no
uneasiness, just as the pallor of the face may be concealed for a time
by rouge.

If we consider that the will must manifest itself in actions which the
body must carry out effectively, we shall understand that a formative
exercise is necessary to develop it by means of its mechanisms.

There is a perfect parallel between the formation of the will and the
coordination of movement of its physiological structure, the striated
muscles. It is evident that exercise is necessary to establish
precision in our movements. We know that we cannot learn to dance
without preliminary exercises, that we cannot play the piano without
practising the movements of the hand; but prior to this, the
fundamental coordination of movements, that is to say, ambulation and
prehension, must have already been established from infancy. It is not
yet so evident to us that similar gradual preparations are necessary
to develop the will.

In the purely physiological functions of the muscular apparatus, our
voluntary muscles do not all act in the same manner, but rather in two
opposite senses; some, for instance, serve to thrust the arm out from
the body, others to draw it near; some serve to bend, others to
straighten the knee; they are, that is to say, "antagonistic" in their
action. Every movement of the body is the result of a combination
between antagonistic muscles, in which now one, now the other prevails
in a kind of collaboration by which the greatest diversity of
movements is made possible to us: movements energetic, graceful,
elegant. It is thus we are enabled to establish not only a noble
attitude of the body, but a delightful motor correspondence with
musical rhythm.

To bring about this intimate combination between antagonistic forces,
all that is necessary is exercise in movement. True, we can _educate_
movement; but this only after the natural coordination has already
taken place; then we can "provoke" special movements as in sporting
games, dances, etc., which movements must, however, be repeatedly
executed by the performer himself in order to produce in him the
possibility of new combinations of movement. Not only in the case of
movements of grace and agility, but also in those of strength, it is
neces
