Like a dancer who has learned to dance

[commonsense]

The best indicator for a competent thinker is that of achieving a successful and fulfilling life.

Without that they still have some learning to do.

Yes. Any ideas on how they will accomplish more learning? Or any initial learning, for that matter?

The best indicator for a competent thinker is that of achieving a successful and fulfilling life.

Is the proof of success and fulfillment objective, or subjective?

Is the proof determined independent of the succeeder?
In other words, does the succeeder fulfill an actual definition of success?

Or, does the succeeder define success and fulfillment?

Yes certainly it is subjective.

Objectivity is no more than consensus of subjectivity anyway.

I once heard an elderly woman refer to her own daughter as, “the mother,” as in, who is the mother of that child not wearing a coat?

Folks have notions of self-identity, as in who they really are, deep down inside. That’s nice.

The objective, impartial assessment defines each as a role, and defines character as the proper fulfillment of that role. (Not a roll.)
