“Asking children to grow virtues hydroponically, looking only within themselves for guidance, is like asking each one to invent a personal language―a pointless and isolating task if there is no community with whom to speak.”

“The rider evolved to serve to the elephant.”

“Trying to run Congress without human relationships is like trying to run a car without motor oil. Should we be surprised when the whole thing freezes up?”

“It really is a fact that liberals are much higher than conservatives on a major personality trait called 'openness to experience.' People who are high on openness to experience just crave novelty, variety, diversity, new ideas, travel. People low on it like things that are familiar, that are safe and dependable.”

“I think Republicans need to take income inequality more seriously. Not because I favor equality of outcomes. I do not. I think the Right is correct to stress merit and earned rewards, not handouts and forced equality. But I think what Republicans are blind to is that power corrupts.”

“Morality binds people into groups. It gives us tribalism, it gives us genocide, war, and politics. But it also gives us heroism, altruism, and sainthood.”

“In all human cultures, the social world has two clear dimensions: a horizontal dimension of closeness or liking, and a vertical one of hierarchy or status. . . . Now imagine yourself happily moving around your two-dimensional social world, a flat land where the X axis is closeness and the Y axis is hierarchy. Then one day, you see a person do something extraordinary, or you have an overwhelming experience of natural beauty , and you feel lifted “up.” But it is not the “up” of hierarchy, it’s some other kind of elevation. This chapter is about that vertical movement. My claim is that the human mind perceives a third dimension, a specifically moral dimension that I will call “divinity.”

“When opponents of evolution object that human beings are not mere apes, they are correct. We are also part bee.”

“Asking children to grow virtues hydroponically, looking only within themselves for guidance, is like asking each one to invent a personal language―a pointless and isolating task if there is no community with whom to speak.”

“Loyalty, respect for authority and some degree of sanctification create a more binding social order that places some limits on individualism and egoism.”

“But if you put individuals together in the right way, such that some individuals can use their reasoning powers to disconfirm the claims of others, and all individuals feel some common bond or shared fate that allows them to interact civilly, you create a group that ends up producing good reasoning as an emergent property of the social system. This is why it's so important to have intellectual & ideological diversity.”
