In addition to all these arguments, it can be shown that a vegetarian diet improves and renders more acute the various senses. Sight and smell, taste and hearing—all are influenced—in some cases more than in others. Frequently patients are enabled to see distances or to smell odours, after living on this diet for some weeks, which they have never been able to do before. The appetite no longer craves the highly-seasoned and stimulating articles of food formerly desired, but is content with the simpler foods. The general acuteness and sense of well-being will more than compensate for any feeling of deprivation that may at first follow the abolition of meat from the diet. There can be no question that the food exerts a tremendous influence over the mental, moral, and emotional life. Says Dr Haig[25]: [25] “Life and Food,” pp. 8-9. “I believe that as the result of a rational, natural and proper diet, producing the best circulation in the great power-house of the human body, we shall get not only freedom from gross disease, but that we shall get, developing gradually, conditions of mind, thought, judgment, and morality, which will, in the future be as different from what they have been in a diseased and degraded past as the light of Heaven is different from the darkness of the dungeon; and that while there are to-day many things in human nature which all believers in the great, and good, and true, can only most heartily deplore, I believe that in the future there will be more harmony, more strength, more beauty, more unselfishness, more love—in a word, a truer and greater and more complete _sanity_.”
