There is a new theory in moral and political philosophy called “Dual Morality.”

It proposes that just as we evolved the five physical senses of sight, smell, touch, hearing and taste to help us navigate our material environment of trees and tornadoes, so too did we evolve two distinct “social senses” to help us successfully maneuver through our social environment of people and groups.

These two social senses come into play depending on how we perceive our surroundings. One of them guides our feelings of right and wrong in times of ease and plenty and the other takes over in times of want or danger. Each of us carries both senses with us at all times, and each of us has a predilection to favor one sense over the other. But we are all capable of using either.

These social senses make themselves known in many ways:

In our political expression we recognize them as “liberalism” vs “conservatism”
As an economic expression we recognize them as “socialistic” vs “capitalistic”
When we describe the psyche we use the terms “personality” vs character”
