Subjective \Sub*jec"tive\, a. [L. subjectivus: cf. F.
   subjectif.]
   1. Of or pertaining to a subject.

   2. Especially, pertaining to, or derived from, one's own
      consciousness, in distinction from external observation;
      ralating to the mind, or intellectual world, in
      distinction from the outward or material excessively
      occupied with, or brooding over, one's own internal
      states.

   Note: In the philosophy of the mind, subjective denotes what
         is to be referred to the thinking subject, the ego;

      drama or painting; a subjective writer.

   Syn: See {Objective}.

   {Subjective sensation} (Physiol.), one of the sensations
      occurring when stimuli due to internal causes excite the
      nervous apparatus of the sense organs, as when a person
      imagines he sees figures which have no objective reality.
