Who said “Behaviour is a mirror in which everyone shows his image.”?

“Though our conduct seems so very different from that of the higher animals, the primary instincts are much alike in them and in us.”

“Of course, behaviorism works. So does torture. Give me a no-nonsense, down-to-earth behaviorist, a few drugs, and simple electrical appliances, and in six months I will have him reciting the Athanasian Creed in public.”

“Still people are dangerous.”

“Perfect behavior is born of complete indifference.”

“Many people love in themselves what they hate in others.”

“Instruction does much, but encouragement everything.”

“Art is long, life short, judgment difficult, opportunity transient.”

“No one would talk much in society, if he knew how often he misunderstands others.”

“One ought, every day at least, to hear a little song, read a good poem, see a fine picture, and, if it were possible, to speak a few reasonable words.”

“More light!”

“Only law can give us freedom.”
