“Until we have the courage to recognize cruelty for what it is -- whether its victim is human or animal -- we cannot expect things to be much better in this world. We cannot have peace among men whose hearts delight in killing any living creature. By every act that glorifies or even tolerates such moronic delight in killing, we set back the progress of humanity.”

“We must fight against the spirit of unconscious cruelty with which we treat the animals. Animals suffer as much as we do. True humanity does not allow us to impose such sufferings on them. It is our duty to make the whole world recognize it. Until we extend our circle of compassion to all living things, humanity will not find peace.”

“We have learned that we cannot live alone, at peace; that our own well-being is dependent on the well-being of nations far away. We have learned that we must live as men, and not as ostriches nor as dogs in the manger. We have learned to be citizens of the world, members of the human community.”

“What sets humans apart from animals is that we have to walk around saying how smart we are, and animals just live their lives.”

“I don't think it is as much a human foible as it is a human curse that we cannot understand the beauty of a thing until it is gone.”

“[...] We have to realize that this wound [of loneliness] is inherent in the human condition and that what we have to do is walk with it instead of fleeing from it. We cannot accept it until we discover that we are loved by God just as we are, and that the Holy Spirit in a mysterious way is living at the centre of the wound.”
