Love animals: God has given them the rudiments of thought and joy untroubled. Do not trouble their joy, don't harrass them, don't deprive them of their happiness, don't work against God's intent. Man, do not pride yourself on superiority to animals; they are without sin, and you, with your greatness, defile the earth by your appearance on it, and leave the traces of your foulness after you - alas, it is true of almost every one of us!
Fyodor DostoevskyPeople talk sometimes of a bestial cruelty, but that's a great injustice and insult to the beasts; a beast can never be so cruel as a man, so artistically cruel. The tiger only tears and gnaws, that's all he can do. He would never think of nailing people by the ears, even if he were able to do it.
Fyodor DostoevskyThere is immeasurably more left inside than what comes out in words. Your thought, even a bad one, while it is with you, is always more profound, but in words it is more ridiculous and dishonorable.
