Durkheim frequently criticized his contemporaries, such as Freud, who tried to explain morality and religion using only the psychology of individuals… - Jonathan Haidt

Putting this all together, it makes sense that WEIRD philosophers since Kant and Mill have mostly generated moral systems that are individualistic, rule-based, and universalist. That’s the morality you need to govern a society of autonomous individuals.

Whatever your identity, background, or political ideology, you will be happier, healthier, stronger, and more likely to succeed in pursuing your own goals if you do the opposite of what Misoponos advised. That means seeking out challenges (rather than eliminating or avoiding everything that “feels unsafe”), freeing yourself from cognitive distortions (rather than always trusting your initial feelings), and taking a generous view of other people, and looking for nuance (rather than assuming the worst about people within a simplistic us-versus-them morality).

Increase similarity, not diversity. To make a human hive, you want to make everyone feel like a family. So don’t call attention to racial and ethnic differences; make them less relevant by ramping up similarity and celebrating the group’s shared values and common identity.49 A great deal of research in social psychology shows that people are warmer and more trusting toward people who look like them, dress like them, talk like them, or even just share their first name or birthday.50 There’s nothing special about race. You can make people care less about race by drowning race differences in a sea of similarities, shared goals, and mutual interdependencies.51
