the righteous mind is like a tongue with six taste receptors. In this analogy, morality is like cuisine: it’s a cultural construction, influenced by accidents of environment and history, but it’s not so flexible that anything goes. You can’t have a cuisine based on tree bark, nor can you have one based primarily on bitter tastes. Cuisines vary, but they all must please tongues equipped with the same five taste receptors.5 Moral matrices vary, but they all must please righteous minds equipped with the same six social receptors.
