Now in fact a man who _can_ stand properly does so, and only a man who can, does. In the former case, fiats of will are unnecessary, and in the latter useless. A man who does not stand properly forms a habit of standing improperly, a positive, forceful habit. The common implication that his mistake is merely negative, that he is simply failing to do the right thing, and that the failure can be made good by an order of will is absurd. One might as well suppose that the man who is a slave of whiskey-drinking is merely one who fails to drink water. Conditions have been formed for producing a bad result, and the bad result will occur as long as those conditions exist. They can no more be dismissed by a direct effort of will than the conditions which create drought can be dispelled by whistling for wind. It is as reasonable to expect a fire to go out when it is ordered to stop burning as to suppose that a man can stand straight in consequence of a direct action of thought and desire. The fire can be put out only by changing objective conditions; it is the same with rectification of bad posture. Of course something happens when a man acts upon his idea of standing straight. For a little while, he stands differently, but only a different kind of badly. He then takes the unaccustomed feeling which accompanies his unusual stand as evidence that he is now standing right. But there are many ways of standing badly, and he has simply shifted his usual way to a compensatory bad way at some opposite extreme. When we realize this fact, we are likely to suppose that it exists because control of the _body_ is physical and hence is external to mind and will. Transfer the command inside character and mind, and it is fancied that an idea of an end and the desire to realize it will take immediate effect. After we get to the point of recognizing that habits must intervene between wish and execution in the case of bodily acts, we still cherish the illusions that they can be dispensed with in the case of mental and moral acts. Thus the net result is to make us sharpen the distinction between non-moral and moral activities, and to lead us to confine the latter strictly within a private, immaterial realm. But in fact, formation of ideas as well as their execution depends upon habit. _If_ we could form a correct idea without a correct habit, then possibly we could carry it out irrespective of habit. But a wish gets definite form only in connection with an idea, and an idea gets shape and consistency only when it has a habit back of it. Only when a man can already perform an act of standing straight does he know what it is like to have a right posture and only then can he summon the idea required for proper execution. The act must come before the thought, and a habit before an ability to evoke the thought at will. Ordinary psychology reverses the actual state of affairs.
