It is certain that in this wonderful new age the development of medical science will lead to the doctors' healing their patients with foods. For the sense of sight, the sense of hearing, of taste, of smell, of touch-- all these are discriminative faculties, their purpose being to separate the beneficial from whatever causeth harm. Now, is it possible that man's sense of smell, the sense that differentiates odours, should find some odour repugnant, and that odour be beneficial to the human body? Absurd! Impossible! In the same way, could the human body, through the faculty of sight-- the differentiator among things visible-- benefit from gazing upon a revolting mass of excrement? Never! Again, if the sense of taste, likewise a faculty that selecteth and rejecteth, be offended by something, that thing is certainly not beneficial; and if, at the outset, it may yield some advantage, in the long run its harmfulness will be established. (155:1) And likewise, when the constitution is in a state of equilibrium, there is no doubt that whatever is relished will be beneficial to health. Observe how an animal will graze in a field where there are a hundred thousand kinds of herbs and grasses, and how, with its sense of smell, it snuffeth up the odours of the plants, and tasteth them with its sense of taste; then it consumeth whatever herb is pleasurable to these senses, and benefiteth therefrom. Were it not for this power of selectivity, the animals would all be dead in a single day; for there are a great many poisonous plants, and animals know nothing of the pharmacopoeia. And yet, observe what a reliable set of scales they have, by means of which to differentiate the good from the injurious. Whatever constituent of their body hath decreased, they can rehabilitate by seeking out and consuming some plant that hath an abundant store of that diminished element; and thus the equilibrium of their bodily components is re- established, and they are rid of their disease.
(155:2)
