Objective \Ob*jec"tive\ ([o^]b*j[e^]k"t[i^]v), a. [Cf. F.
   1. Of or pertaining to an object.
      [1913 Webster]

   2. (Metaph.) Of or pertaining to an object; contained in, or
      having the nature or position of, an object; outward;
      external; extrinsic; -- an epithet applied to whatever is
      exterior to the mind, or which is simply an object of
      thought or feeling, as opposed to being related to
      thoughts of feelings, and opposed to subjective.
      [1913 Webster +PJC]

            In the Middle Ages, subject meant substance, and has
            this sense in Descartes and Spinoza: sometimes,
            also, in Reid. Subjective is used by William of
            Occam to denote that which exists independent of
            mind; objective, what is formed by the mind. This
            shows what is meant by realitas objectiva in
            Descartes. Kant and Fichte have inverted the
            meanings. Subject, with them, is the mind which
            knows; object, that which is known; subjective, the
            varying conditions of the knowing mind; objective,
            that which is in the constant nature of the thing
            known.                                --Trendelenburg.
      [1913 Webster]

            Objective has come to mean that which has
            independent existence or authority, apart from our
            experience or thought. Thus, moral law is said to
            have objective authority, that is, authority
            belonging to itself, and not drawn from anything in
            our nature.                           --Calderwood
      [1913 Webster]

   3. Hence: Unbiased; unprejudiced; fair; uninfluenced by
      personal feelings or personal interests; considering only
      the facts of a situation unrelated to the observer; -- of
      judgments, opinions, evaluations, conclusions, reasoning

            Objective means that which belongs to, or proceeds
            from, the object known, and not from the subject
            knowing, and thus denotes what is real, in
            opposition to that which is ideal -- what exists in
            nature, in contrast to what exists merely in the
            thought of the individual.            --Sir. W.
      [1913 Webster]

   4. (Gram.) Pertaining to, or designating, the case which
      follows a transitive verb or a preposition, being that
      case in which the direct object of the verb is placed. See
      Accusative, n.
      [1913 Webster]

   Note: The objective case is frequently used without a
         governing word, esp. in designations of time or space,
         where a preposition, as at, in, on, etc., may be
         [1913 Webster]

               My troublous dream [on] this night doth make me
               sad.                               --Shak.
         [1913 Webster]

               To write of victories [in or for] next year.
         [1913 Webster]

   Objective line (Perspective), a line drawn on the
      geometrical plane which is represented or sought to be

   Objective plane (Perspective), any plane in the horizontal
      plane that is represented.

   Objective point, the point or result to which the
      operations of an army are directed. By extension, the
      point or purpose to which anything, as a journey or an
      argument, is directed.
      [1913 Webster]

   Syn: Objective, Subjective.

   Usage: Objective is applied to things exterior to the mind,
          and objects of its attention; subjective, to the
          operations of the mind itself. Hence, an objective
          motive is some outward thing awakening desire; a
          subjective motive is some internal feeling or
          propensity. Objective views are those governed by
          outward things; subjective views are produced or
          modified by internal feeling. Sir Walter Scott's
          poetry is chiefly objective; that of Wordsworth is
          eminently subjective.
          [1913 Webster]

                In the philosophy of mind, subjective denotes
                what is to be referred to the thinking subject,
                the ego; objective what belongs to the object of
                thought, the non-ego.             --Sir. W.
