Vegetarianism is my religion. I became a consistent vegetarian some twenty-three years ago. Before that, I would try over and over again. But it was sporadic. Finally, in the mid-1960s, I made up my mind. And I've been a vegetarian ever since. When a human kills an animal for food, he is neglecting his own hunger for justice. Man prays for mercy, but is unwilling to extend it to others. Why should man then expect mercy from God? It's unfair to expect something that you are not willing to give. … This is my protest against the conduct of the world. To be a vegetarian is to disagree — to disagree with the course of things today. Nuclear power, starvation, cruelty — we must make a statement against these things. Vegetarianism is my statement. And I think it's a strong one.
