Tom Jacobs explains how ethicist Jonathan Haidt’s framework of five moral realms applies differently to liberals and conservatives:

In a creative attempt to move beyond red-state/blue-state clichés, Haidt has created a framework that codifies mankind’s multiplicity of moralities. His outline is simultaneously startling and reassuring—startling in its stark depiction of our differences, and reassuring in that it brings welcome clarity to an arena where murkiness of motivation often breeds contention.

He views the demonization that has marred American political debate in recent decades as a massive failure in moral imagination. We assume everyone’s ethical compass points in the same direction and label those whose views don’t align with our sense of right and wrong as either misguided or evil. In fact, he argues, there are multiple due norths.

Of Haidt’s five moral realms, the one that causes the most friction between cosmopolitan liberals and traditionalist conservatives is purity/sanctity. To a 21st-century secular liberal, the concept barely registers. Haidt notes it was part of the Western vocabulary as recently as the Victorian era but lost its force in the early 20th century when modern rules of proper hygiene were codified. With the physical properties of contamination understood, the moral symbolism of impurity no longer carried much weight.

But the impulse remains lodged in our psyches, turning up in both obvious and surprising ways. You can hear strong echoes of it when the pope rails against materialism, insisting we have been put on Earth to serve a loftier purpose than shopping until we drop. It can also be found in the nondenominational spiritual belief that we all contain within us a piece of the divine. (Although it’s sometimes used in a tongue-in-cheek way in our society, the phrase “my body is a temple” is reflective of the purity/sanctity impulse.)
