Darwin and the golden rule: how to distinguish differences of degree from differences of kind using mechanisms

Biology & Philosophy Aims and scope Submit manuscript

Abstract

Darwin claimed that human and animal minds differ in degree but not in kind, and that ethical principles such as the Golden Rule are just an extension of thinking found in animals. Both claims are false. The best way to distinguish differences in degree from differences in kind is by identifying mechanisms that have emergent properties. Recursive thinking is an emergent capability found in humans but not in other animals. The Golden Rule and some other ethical principles such as Kant’s categorical imperative require recursion, so they constitute ethical thinking that is restricted to humans. Changes in kind have tip** points resulting from mechanisms with emergent properties.
