\U*til`i*ta"ri*an\, n.
One who holds the doctrine of utilitarianism.
      The utilitarians are for merging all the particular
      virtues into one, and would substitute in their place
      the greatest usefulness, as the alone principle to
      which every question respecting the morality of actions
      should be referred.                      --Chalmers.
      But what is a utilitarian? Simply one who prefers the
      useful to the useless; and who does not? --Sir W.
                                               Hamilton.
