"You [the people] are a many-headed beast."

"Man is the only animal that blushes. Or needs to."

"The one excellent thing that can be learned from a lion is that whatever a man intends doing should be done by him with a whole-hearted and strenuous effort."

"Give your dog or cat respect, patience, understanding and love. And if you just change to one vegetarian day a week, that's a wonderful step that will save animal lives. It means you have chosen something kind instead of something cruel."
