sentiment awakens, his heart opens to love or hatred, and he expresses
his new emotion not by cries alone, nor yet by speech; he smiles upon
his mother, and his first gesture is a smile. Beings endowed only with
the sensitive life, have no smile; animals do not laugh.

This marvelous correspondence of the organs with the sentiment arises
from the close union of soul and body. The brain ministers to the
operations of the soul. Every sentiment must have its echo in the brain,
in order to be unerringly transmitted by the organic apparatus.

_Ex visu cognoscitur vir._ ("The man is known by his face.") The rôle of
dissimulation is a very difficult one to sustain.

2. _Gesture is the Interpreter of Speech._--Gesture has been given to
man to reveal what speech is powerless to express. For example: _I
love_. This phrase says nothing of the nature of the being loved,
nothing of the fashion in which one loves. Gesture, by a simple
movement, reveals all this, and says it far better than speech, which
would know how to render it only by many successive words and phrases. A
gesture, then, like a ray of light, can reflect all that passes in the
soul.

Hence, if we desire that a thing shall be always remembered, we must not
say it in words; we must let it be divined, revealed by gesture.
Wherever an ellipse is supposable in a discourse, gesture must intervene
to explain this ellipse.

3. _Gesture is an Elliptical Language._--We call ellipse a hidden
meaning whose revelation belongs to gesture. A gesture must correspond
to every ellipse. For example: "This medley of glory and gain vexes me."
