As evidence accumulates that the "rugged individualism" of singular selfhood is a myth, and the profound interdependence of selves becomes apparent, our default self is gradually shifting from singular to plural. But until the co-dependent, co-creative nature of selfhood becomes obvious, a distinct term may come in handy. Call the emerging self the "Plural Self" (aka, the Superself.)
Sir Winston Churchill famously said, "In wartime, truth is so precious that she should always be attended by a bodyguard of lies." The truth, long protected by the self-serving lie of the Singular Self, is the Plural Self.
Whereas the Singular Self downplays our mutual dependence, the Plural Self embraces interdependence. Whereas the Singular Self excludes, the Plural Self contains multitudes\. The Singular Self prioritizes agency; the Plural Self, harmony.
The current ideological divide in politics stems from antithetical views of the self. Conservatives caution that a pluralistic notion of selfhood may inhibit individual agency, whereas Progressives argue that Singular Selfhood rationalizes an inequitable distribution of recognition and reward.
As ways are found to safeguard individual initiative from the inertia of more inclusive decision-making, the Plural Self will supplant the Singular Self as the new default self. With luck, this will happen in time to welcome intelligent machines into the club.
