The vegetarians condemn the use of meat. Some of them are called fruitarians. It is very difficult to decide who are the most representative of them. Some advocate the use of nothing but fruit and nuts. Others add cereals to this. Others use vegetables in addition. Some even allow the use of dairy products and eggs, that is, all foods except flesh. They say that meat is an unnatural food for man and condemn its use on moral grounds. It is difficult to decide what is natural, for we find that man is very adaptable, being able to live on fruits in the tropics and almost exclusively on flesh food, largely fat, in the arctic regions. In nature the strong live on the weak and the intelligent on the dull. There is no sentiment in nature. In her domain might, physical or mental, makes right. Sentiments of right and justice are not highly developed except among human beings, and even there they are so weakly implanted that it takes but little provocation for civilized man to bare his teeth in a wolfish snarl. With some vegetarianism is largely a matter of esthetics, ethics and morality. Morality is based on expediency, so it really is a question whether meat is an advantageous food or not. Another vegetarian argument is that man's anatomy proves that he was not intended by nature to eat meat. Good arguments have been used on both sides, but they are not very convincing nor are they conclusive. It is hard to draw any lines fairly. Another objection to meat is that it is unclean and full of poisons, that these poisons produce various diseases, such as cancer. We are also informed that refined sugar causes cancer, and the belief in tomatoes as a causative factor is not dead. Cancer is without doubt caused principally by dietary indiscretions but it is impossible to single out any one food. No matter what foods we eat, we are compelled to be careful or they will be unclean. Those who wish clean meat can obtain it. The amount of poison or waste in a proper portion of meat is so small that we need give it no thought. Those who eat in moderation can take meat once a day during cold weather and enjoy splendid health. During warm weather it should be eaten more seldom. On the other hand, meat is not necessary. We need a certain amount of protein, which we can obtain from nuts, eggs, milk, cheese, peanuts, peas, beans, lentils, cereals and from other food in smaller amounts. The amount of protein needed is small--about one-fifth of what the physiologists used to recommend.
