“Some animals are surprisingly sensitive to the plight of others. Chimpanzees, who cannot swim, have drowned in zoo moats trying to save others. Given the chance to get food by pulling a chain that would also deliver an electric shock to a companion, rhesus monkeys will starve themselves for several days.“

Bloody good job, really – after all, with great power comes great responsibility. Imagine if their weapons technology advanced at a greater pace than their moral development – why, it’d be awful.
