Do not take their joy from them

Love the animals; God gave them the rudiments of thought and untroubled joy. Do not trouble it, do not torment them, do not take their joy from them, do not go against God’s purpose. Man, do not exalt yourself above the animals; they are sinless.

From The Brothers Karamazov by Fyodor Dostoyevksy as quoted in Compassion by the Pound by Norwood and Lusk
