Self-love \Self`-love`\, n.
   The love of one's self; desire for personal happiness;
   tendency to seek one's own benefit or advantage. --Shak.
   [1913 Webster]

         Self-love, the spring of motion, acts the soul. --Pope.
   [1913 Webster]

   Syn: Selfishness.

   Usage: Self-love, Selfishness. The term self-love is used
          in a twofold sense: 1. It denotes that longing for
          good or for well-being which actuates the breasts of
          all, entering into and characterizing every special
          desire. In this sense it has no moral quality, being,
          from the nature of the case, neither good nor evil. 2.
          It is applied to a voluntary regard for the
          gratification of special desires. In this sense it is
          morally good or bad according as these desires are
          conformed to duty or opposed to it. Selfishness is
          always voluntary and always wrong, being that regard
          to our own interests, gratification, etc., which is
          sought or indulged at the expense, and to the injury,
          of others. "So long as self-love does not degenerate
          into selfishness, it is quite compatible with true
          benevolence." --Fleming. "Not only is the phrase
          self-love used as synonymous with the desire of
          happiness, but it is often confounded with the word
          selfishness, which certainly, in strict propriety,
          denotes a very different disposition of mind."
          --Slewart.
          [1913 Webster]
