Dr Robinson was fortunate enough to be able to test his theory on some sixty babies in the first hours of their life, and was
triumphantly successful. He clasped their hands about a slender rod, and they swung from it like athletes, without apparent
discomfort, by the half minute; many of us grown people could not do as well. Such a remarkable power of hands and arms
has for ages been of no especial use to the human race, and it fades out in a few weeks, but for many months the arms keep
ahead of the legs in development.
Here was not only strength of arms, but the ability to perform quite skillfully an action, that required the working together of
a number of muscles to a definite end, — the action namely, of clasping an object with the hand. This is one of several
actions that come ready-made to the baby at birth, before he can possibly have had any chance to learn them, or any idea of
what they are for. Babies sneeze, swallow, and cry on the first day; they shut their eyes at a bright light, or at a torch. On the
first day, moreover, they have been seen to start at a sound ora jar; Preyer observed hiccoughing, choking, coughing, and
spreading the toes when the soles were tickled; and Darwin saw yawning and stretching within the first week, though I do not
know that any one has seen it on the first day.
These movements are all of the class called reflex, — movements, that is, in which the bodily mechanism is set off by some
outside action on the senses, as a gun is set off by a touch onthe trigger. Thus, when a tickling affects the mucous membrane,
a sneeze executes itself without any will of ours; when our sense of sight perceives a swift missile coming, the neck muscles
mechanically jerk the head to one side.
We grown people have, however, a good deal of power of holding in our reflexes, — " inhibiting" them, as the technical
expression is, — but the baby has none at all. If they had a highly developed reflex activity, babies would be in real danger
from the unrestrained acts of their own muscles, as we see in the case of convulsions, which show reflex action at its extreme.
But the actions I have mentioned are about all the reflex movements that have been noted in new-born babies, except what
are called the periodic reflexes, such as breathing, the heartbeat, the contractions of the arteries, and all the regular muscular
actions of organic life.
That so complex a system of movement as these periodic reflexes should be so readily touched into motion upon contact with
air and food, to maintain itself afterward by the interplay of the bodily mechanism and external forces, shows a ready-made
hereditary activity far more than the sudden reflexes do. Itdoes not work quite smoothly at first, however: the establishment
of breathing, for instance, is irregular, and often difficult. Even the sudden reflexes are slower and less perfect than with older
people.
There is another class of movements, often confused with the reflex — that is, instinctive movements. Real grasping (as
distinguished from reflex grasping), biting, standing, walking, are examples of this class. They are race movements, the habits
of the species to which the animal belongs, and every normal member of the species is bound to come to them; yet they are
not so fixed in the bodily mechanism as the reflex movements. The stimulus to them seems to come more from within than
from without — yet not from reason and will, but from some blind impulse. This impulse is usually imperfect, and the child
has to work his own way to the mastery of the movements. Yetthough certain reflex activities are inherited in a morehighly
developed condition than any human instincts, the instincts areat bottom always hereditary, which is not the case with the
reflexes—any one may teach his muscles new reflex movements, unknown to his ancestors. A musician does it every time
that he practices new music till his hands will run it off of their own accord, while he is thinking of something else. But
instinct cannot be thus acquired. The amazing instincts of the lower animals; the imperfect and broken condition of the
instincts in man, yet the deep hold that they have on him; the mingling of inherited necessity and individual freedom in the
way in which they are worked out; the mystery of the physiological method by which they act (while that of reflex movement
is fairly well understood, up to a certain point); the light they seem always about to shed for the biologist on the profoundest
problems of heredity, and for the philosopher on those of free will and personality, — these things make instinct one of the
great fields of present research, and I must not venture into it, though it is of importance in trying to understand a baby.
I shall say only that while instinct does not appear in the lowest animals (whose action is all of the reflex type), and is for a
time a sign of rising rank in the scale of life, it reaches its culmination with the insects, and as we approach man it is the
breaking up of the instincts that is in its turn a sign of advancement to higher life. The little chicken runs about as soon as it is
out of its shell, and even the monkey baby is able to take care ofitself in a few months. Nothing is so helpless as the human
