Utensils and fire and seasoning -- the great transformation in the natural diet of human beings, and the great rebellion against Nature. This is known as cooking or cuisine. And in cooking we find the following three regrettable elements: 1. How can one, using utensils and heat and seasonings, make it possible to eat things which one cannot ordinarily eat? 2. How can one make things taste good, and stuff a lot into one's stomach? 3. How can one destroy the life and cells of one's food, thereby diminishing its effect? What we must be aware of here is that even the provincial cooking of a hundred years ago varies not a bit from these themes, and even if we look back 50 or 100 thousand years, there is little difference. They say that our remaining canine teeth prove that primitive human beings were carnivorous animals, but I do not believe it. Almost a million and a half years ago human beings had already learned how to use fire, thereby changing their natural diets. Canine teeth were no doubt used to open and eat chestnuts and other hard nuts. Human beings are born with both fists tightly clenched. If you put a stick in a baby's hands it will hang from the stick, and if you lift the stick, the upper half of the baby's body will follow. If you provide some stimulus to the soles of its feet, the baby's toes will bend as if they are trying to grasp something. This indicates that, even now, the structure of the human body is adapted to climbing trees in search of fruit and nuts, and it has changed little from millions of years ago. This also shows that there ought to be no change in the human diet, either. It was, after all, quite impossible for human beings to become lions or hyenas. In addition to (or in connection with) the three elements of cooking described above, human beings have committed further crimes: They have changed the shape and appearance of their food, pulverized it, analyzed it, extracted it, mixed it, and compounded it.
