In this video Richard Kamber comments on David Hume’s book, "A Treatise of Human Nature", current research in evolutionary psychology and ethics. Kamber points out the idea of understanding ethics, how we see the right and wrong and how this is related to us, to our nature and our feelings, the interaction between subject and object according to our experience. He also illustrates how evolutionary psychology and its application to ethics have a greater variation between vicious and virtue according to the power of culture over human brain.
