GROWING TENDENCY TOWARD EMOTIONAL CONTROL.--Among civilized peoples
there is a constantly growing tendency toward emotional control.
Primitive races express grief, joy, fear, or anger much more freely than
do civilized races. This does not mean that primitive man feels more
deeply than civilized man; for, as we have already seen, the crying,
laughing, or blustering is but a small part of the whole physical
expression, and one"s entire organism may be stirred to its depths
without any of these outward manifestations. Man has found it advisable
as he has advanced in civilization not to reveal all he feels to those
around him. The face, which is the most expressive part of the body, has
come to be under such perfect control that it is hard to read through it
the emotional state, although the face of civilized man is capable of
expressing far more than is that of the savage. The same difference is
observable between the child and the adult. The child reveals each
passing shade of emotion through his expression, while the adult may
feel much that he does not show.
