Anoetic \An`o*et"ic\, a. [Gr. ? unthinkable; ? priv. + ?
   perceptible, thinkable.]
   1. Unthinkable. [Rare]
      [Webster 1913 Suppl.]

   2. (Psychol.) Not subject to conscious attention; having an
      indefinite, relatively passive, conscious being;
      characteristic of the "fringe" or "margin" of
      consciousness.
      [1913 Webster]

            Presentation considered as having an existence
            relatively independent of thought, may be called
            sentience, or anoetic consciousness. Thought and
            sentience are fundamentally distinct mental
            functions.                            --G. F. Stout.
