Friedrich Nietzsche
Danger for vegetarians
A diet that consists predominantly of rice leads to the use of opium and narcotics, just as a diet that consists predominantly of potatoes leads to the use of alcohol. But it also has subtler effects that include ways of thinking and feeling that have narcotic effects. This agrees with the fact that those who promote narcotic ways of thinking and feeling, like some Indian Gurus, promote a diet that is entirely vegetarian and would like to impose that as a law upon the masses. In this way they want to create and strengthen a need that they are in a position to satisfy.
