[Bain's footnote 101: This is true in by far the greater number of instances. Nevertheless, there are some of the signs of feeling that have an intrinsic efficacy, on very manifest grounds. While the meanings of the smile and the frown could have been reversed, if the association had been the other way, there is an obvious suitability in the harsh stunning tones of the voice to signify anger and to inspire dread, and a like suitability in the gentle tones to convey affection and kindly feeling. We might have contracted the opposing associations, had the facts been so arranged, just as in times of peace, we associate joy with deafening salvos of artillery; and as loud, sharp-pealing laughter serves in the expression of agreeable feeling. But there is a gain of effect when the signs employed are such as to chime in, by intrinsic efficacy, with the associated meanings. On this coincidence depend the refinements of elocution, oratory, and stage display.--_B._ [The fact here brought to notice by Mr. Bain is, that certain of the natural expressions of emotion have a kind of analogy to the emotions they express, which makes an opening for an instinctive interpretation of them, independently of experience. But if this be so (and there can be little doubt that it is so) the suggestion takes place by resemblance, and therefore still by association.--_Ed._]] [Mill's footnote 10: "It has been very justly remarked, that if all men had uniformly spoken the same language, in every part of the world, it would be difficult for us not to think [believe] that there is a natural connexion of our ideas, and the words which we use to denote them."--_Brown_, _Lectures_, ii. p. 80. 2d ed.] The process of our Belief in this case, then, is evidently, as follows. Our sensations are inseparably associated with the idea of our bodies. A man cannot think of his body without thinking of it as sensitive. As he cannot think of his own body without thinking of it as sensitive, so he cannot think of another man's {358} body, which is like it, without thinking of it as sensitive. It is evident that the association of sensitiveness is more close with certain parts of the complex idea, our bodies, than with other parts; because the association equally follows the idea of horse, of dog, of fowl, and even of fish, and insect: and it will be found, I think, that there is nothing with which it is so peculiarly united as the idea of spontaneous motion. What is the reason we do not believe there is any sensation in the most curiously-organized vegetable; while we uniformly believe there is in the polypus, and the microscopic insect? Nothing whatsoever can be discovered, but a strong association which exists in the one case, and is wanting in the other. And this is one of the most decisive of all experiments to prove the real nature of Belief.
