A psychiatrist, who also teaches human behaviour to MBAs, was informing my curious self: "If a child is raised in a cave with animals, says dogs or lions, and he never comes in contact with humans, he would behave as dogs or lions. The natural instinct of morality would become dormant owing to the dominant environment. But if you take out the same uncultured human being from this animalistic environment and put into human environment, he'd again start behaving as humans. All those moral instincts of shame, cleanness would return. On the other hand, if you take dogs and lions out of their wild environment and attach 'em with humans, they won't stop behaving as dogs and won't behave as humans!"
What does this suggest to you?
