elements. These scientists even hold that there is no need for man to cook his food. They argue that he should be able to subsist very well on food cooked by the Sun's warmth, even as all the lower animals are able to do; and they say that the most nutritious elements in the food are destroyed in the process of cooking, and that those things that cannot be eaten uncooked could not have been intended for our food by Nature.
If this view be correct, it follows that we are at present wasting a lot of our precious time in the cooking of our food. If we could live on uncooked food alone, we should be saving so much time and energy, as well as money, all of which may be utilised for more useful purposes.
Some people will doubtless say that it is idle and foolish to speculate on the possibility of men taking to uncooked food, since there is absolutely no hope of their ever doing it. But we are not considering at present what people will or will not do, but only what they ought to do. It is only when we know what the ideal kind of diet is that we shall be able more and more to approximate our actual to the ideal. When we say that a fruit-diet is the best, we do not, of course, expect all men to take to it straight-way. We only mean that, if they should take to this diet, it would be the best thing for them.
