Buddhist moral psychology represents a distinctive contribution to contemporary moral discourses. Most Western ethicists neglect to problematize perception at all, and few suggest that ethical engagement begins with perception. But this is a central idea in Buddhist moral theory. Human perception is always perception-as. We see someone as a friend or as an enemy; as a stranger or as an acquaintance. We see objects as desirable or as repulsive. We see ourselves as helpers or as competitors, and our cognitive and action sets follow in train.
