The system of diet in question, greatly improves, exalts, and perfects the senses. The sight, smell, and taste are rendered greatly superior by it. The difference in favor of the hearing and the touch may not be so obvious; nevertheless, it is believed to be considerable. But the change in the other senses--the first three which I have named--even when we reform as late as at thirty-five or forty, is wonderful. I do not wish to encourage, by this, a delay of the work of reformation; we can never begin it too early. Vegetable diet favors beauty of form and feature. The forms of the natives of some of the South Sea Islands, to say nothing of their features, are exceedingly fine. They are tall and well proportioned. So it is with the Japanese and Chinese, especially of the interior, where they subsist almost wholly on rice and fruits. The Japanese are the finest men, physically speaking, in Asia. The New Hollanders, on the contrary, who live almost wholly on flesh and fish, are among the most meagre and ugly of the human race, if we except the flesh-eating savages of the north, and the Greenlanders and Laplanders. In short, the principle I have here advanced will hold, as a _general rule_, I believe, other things being equal, throughout the world. If it be asked whether I would exalt beauty and symmetry into virtues, I will only say that they are not without their use in a virtuous people; and I look forward to a period in the world's history, when all will be comparatively well formed and beautiful. Beauty is exceedingly influential, as every one must have observed who has been long in the world; at least, if he has had his eyes open. And it is probably right that it should be so. Our beauty is almost as much within our control, as a race, as our conduct. A vegetable diet, moreover, promotes and preserves a clearness and a generally healthful state of the mental faculties. I believe that much of the moral as well as intellectual error in the world, arises from a state of mind which is produced by the introduction of improper liquids and solids into the stomach, or, at least, by their application to the nervous system. Be this as it may, however, there is nothing better for the brain than a temperate diet of well-selected vegetables, with water for drink. This Sir Isaac Newton and hundreds of others could abundantly attest. It also favors an evenness and tranquillity of temper, which is of almost infinite value. The most fiery and vindictive have been enabled, by this means, when all other means had failed, to transform themselves into rational beings, and to become, in this very respect, patterns to those around them. If this were its only advantage, in a physiological point of view, it would be of more value than worlds. It favors, too, simplicity of character. It makes us, in the language of the Bible, to remain, or to become, as little children, and it preserves our juvenile character and habits through life, and gives us a green old age.
