“Humor is a developed sense, stemming basically from cruelty. The more primitive a mind, the less selectivity exists. … A man slips on a banana peel and breaks his back.

A baby, a child, a moron is incapable of practicing empathy. He cannot identify himself with another individual. He is regrettably autistic; his own rules are arbitrary”
