noun

  1. 1

    A hypothetical particle whose existence and configuration can make a moral judgment true.

Etymology

Coined by American legal philosopher Ronald Dworkin in late 20th c.; by surface analysis, mor(al) + -on. The obvious idea that the homonymy with the usual sense of moron was likely intentional has been supported by some of Dworkin's fellow philosophers.
