During these weeks a note of real desire, unheard before, appeared in her voice. Her face had at times, when she saw something new, or when she gazed at us while we talked to her, an expression of inquiry and effort to comprehend, with lips drawn in and brow tense. No one could watch her and not see the beginnings of some sort of mental life.
VIII
THE ERA OF HANDLING THINGS
She sprang into this era suddenly, within four days. It was not infrequently thus, and perhaps more and more as the little brain grew complex. Some power that had been slowly developing would leap up into completion, unlocking a dozen other doors of mental life. To put it physiologically, some one new connection established between brain cells would bring a whole network of others into coöperation—the more easily as ancestral nerve paths seemed often to open up at a touch.
When the baby had passed ten days of her fifth month, she was still grasping half mechanically. On the eleventh day, lying on her back, she held her rattle above her and looked at it carefully. Her attention had turned to the things that she grasped. She had come before to the perception of a world of objects, but apparently only now to the realization of it. And thereupon, that very day, I saw that she was no longer using eyes and hands merely as means of getting mouth sensations; she was holding objects, looking at them, and pulling them about, for some moments, before they went to her mouth.
The pleasure of this handling seemed to be in the free movement of the objects (seen and felt at the same time), not especially in the touch sensations. When this new pleasure was exhausted, things went to the mouth as before for the enjoyment of touch. It was long before the fingers rivaled the lips in pure æsthetic touch enjoyment; perhaps they never do, else the dandy would finger his cane knob, instead of mouthing it, girls would smooth rose-leaves across their finger tips, not their lips, and a kiss would have no higher rank than a hand-clasp. But for grasping purposes the supremacy now passed promptly over to the hands, and from this week the habit of grasping with the mouth by head movements declined and disappeared.
In a few hours the baby was reaching for everything near her, and in three days more her desire to lay hold on things was the dominant motive of her life. Her grasping was still oftener with both hands than one, and was somewhat slow, but always accurate. Some babies learn to grasp more suddenly than she did, and often miss their aim; but with her cautious method of bringing down her hands toward an object from either side, penning it in between, she could hardly make errors. The thing once corralled, she would pull it around, perhaps a minute, then put it to her mouth.
It is an epoch of tremendous importance when the baby first, with real attention, brings sight and touch and muscle feeling to bear together on an object. “In a very deep sense,” says John Fiske, “all human science is but the increment of the power of the eye, and all human art is the increment of the power of the hand. Vision and manipulation—these in their countless indirect and transfigured forms are the two coöperating factors in all intellectual progress.” And the first great result of this coöperation is the completion of vision itself. It cannot be doubted that it is mainly by studying objects with eye and hand together that we get our ability to see solid form. A colt grasping his ear of corn with his teeth, even a puppy licking and turning his bone all over, or a kitten tapping a spool to and fro and hugging it in her paws, without losing sight of it—none of these can bring the united powers of three senses to bear on an object so perfectly as a monkey or human baby can, holding it in the most convenient positions, turning it this way and that, seeing every part, feeling it with finger tips and mouth; and it is doubtful if the quadrupeds ever attain to as clear a sense of form as we do.
In these first days of the passion for grasping at things, the baby reached for flat figures as readily as for solid objects; but (to look ahead a little) she learned to discriminate with surprising ease, and after the first week I have only three or four notes of her trying to pick up such things as pictures on a page, roses on a quilt, shadows in the sun. Yet I do not think this was because she gained quickly any such sense of the difference between plane and solid form as we have, but rather that she learned quickly to associate a certain look about an object with the experience of being able to get hold of it.
The reason that I think so is that even weeks later, when she was six months old, she showed signs of having no real ability to judge form by the eye. At that age she turned a round cracker round and round at her lips, trying to find the corner to bite, as she was used to doing with square ones. And the only time she was ever taken in by a flat figure afterward was when (at nine months old) she tried a long time to capture the swaying shadow of a rope end on the deck of a yacht; things that moved could always be taken hold of in her experience, and she went solely by experience, not by any general ideas of form.
But such general ideas really require a good deal of development of reason—so much that it is likely the lower animals never rise to them. We must think of the baby’s seeing, therefore, as rounding out but slowly to full equality with ours in such matters as estimates of form, distance, and size, where much experience and some reason are required.
