We sometimes imagine that the bird's movements are to be explained by supposing that he is engaged in the search for food in these evolutions. But when we reflect how small a quantity of food his little crop will contain, we shall be at once convinced that a large proportion of his apparent pecking for food is only make-believe, and that he moves thus incessantly not so much on account of the end he seeks to attain by it, as on account of the very pleasure of the motion. He hops about and pecks, not for the love of any thing he expects to find, but just for the love of hopping and pecking.
The real explanation is that the food which he has taken is delivering up, within his system, the force stored in it that was received originally from the beams of the sun, while the plant which produced it was growing. This force must have an outlet, and it finds this outlet in the incessant activity of the bird's muscles and brain. The various objects which attract his attention without, invite the force to expend itself in certain special directions; but the impelling cause is within, and not without; and were there nothing without to serve as objects for its action, the necessity of its action would be none the less imperious. The lion, when imprisoned in his cage, walks to and fro continuously, if there is room for him to take two steps and turn; and if there is not room for this, he moves his head incessantly from side to side. The force within him, which his vital organs are setting at liberty from its imprisonment in his food, must in some way find issue.
Mothers do not often stop to speculate upon, and may even, perhaps, seldom observe the restless and incessant activity of birds, but that of their children forces itself upon their attention by its effects in disturbing their own quiet avocations and pleasures; and they often wonder what can be the inducement which leads to such a perpetual succession of movements made apparently without motive or end. And, not perceiving any possible inducement to account for it, they are apt to consider this restless activity so causeless and unreasonable as to make it a fault for which the child is to be censured or punished, or which they are to attempt to cure by means of artificial restraints. They would not attempt such repressions as this if they were aware that all this muscular and mental energy of action in the child is only the outward manifestation of an inward force developed in a manner wholly independent of its will—a force, too, which must spend itself in some way or other, and that, if not allowed to do this in its own way, by impelling the limbs and members to outward action, it will do so by destroying the delicate mechanism within. We see this in the case of men who are doomed for long periods to solitary confinement. The force derived from their food, and released within their systems by the vital processes, being cut off by the silence and solitude of the dungeon from all usual and natural outlets, begins to work mischief within, by disorganizing the cerebral and other vital organs, and producing insanity and death.
Common Mistake.
We make a great mistake when we imagine that children are influenced in their activity mainly by a desire for the objects which they attain by it. It is not the ends attained, but the pleasurable feeling which the action of the internal force, issuing by its natural channels, affords them, and the sense of power which accompanies the action. An end which presents itself to be attained invites this force to act in one direction rather than another, but it is the action, and not the end, in which the charm resides.
Give a child a bow and arrow, and send him out into the yard to try it, and if he does not happen to see any thing to shoot at, he will shoot at random into the air. But if there is any object which will serve as a mark in sight, it seems to have the effect of drawing his aim towards it. He shoots at the vane on the barn, at an apple on a tree, a knot in a fence—any thing which will serve the purpose of a mark. This is not because he has any end to accomplish in hitting the vane, the apple, or the knot, but only because there is an impulse within him leading him to shoot, and if there happens to be any thing to shoot at, it gives that impulse a direction.
It is precisely the same with the incessant muscular activity of a child. He comes into a room and sits down in the first seat that he sees. Then he jumps up and runs to another, then to another, until he has tried all the seats in the room. This is not because he particularly wishes to try the seats. He wishes to move, and the seats happen to be at hand, and they simply give direction to the impulse. If he were out of doors, the same office would be fulfilled by a fence which he might climb over, instead of going through an open gate close by; or a wall that he could walk upon with difficulty, instead of going, without difficulty, along a path at the foot of it; or a pole which he could try to climb, when there was no motive for climbing it but a desire to make muscular exertion; or a steep bank where he can scramble up, when there is nothing that he wishes for on the top of it.
In other words, the things that children do are not done for the sake of the things, but for the sake of the doing.
Parents very often do not understand this, and are accordingly continually asking such foolish questions as, "George, what do you wish to climb over that fence for, when there is a gate all open close by?" "James, what good do you expect to get by climbing up that tree, when you know there is nothing on it, not even a bird's nest?" and, "Lucy, what makes you keep jumping up all the time and running about to different places? Why can't you, when you get a good seat, sit still in it?"
The children, if they understood the philosophy of the case, might answer, "We don't climb over the fence at all because we wish to be on the other side of it; or scramble up the bank for the sake of any thing that is on the top of it; or run about to different places because we wish to be in the places particularly. It is the internal force that is in us working itself off, and it works itself off in the ways that come most readily to hand."
