  Objective \Ob*jec"tive\ ([o^]b*j[e^]k"t[i^]v), a. [Cf. F.
     objectif.]
     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
                                                    (Fleming's
                                                    Vocabulary).
        [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
        processes.
        [PJC]
  
              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.
                                                    Hamilton.
        [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
           supplied.
           [1913 Webster]
  
                 My troublous dream [on] this night doth make me
                 sad.                               --Shak.
           [1913 Webster]
  
                 To write of victories [in or for] next year.
                                                    --Hudibras.
           [1913 Webster]
  
     Objective line (Perspective), a line drawn on the
        geometrical plane which is represented or sought to be
        represented.
  
     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.
                                                    Hamilton
            [1913 Webster]
