            Duty is a graver term than obligation. A duty hardly

   7. (Com.) Tax, toll, impost, or customs; excise; any sum of
      money required by government to be paid on the

      [1913 Webster]

   Note: An impost on land or other real estate, and on the
         stock of farmers, is not called a duty, but a direct
         tax. [U.S.]
         [1913 Webster]

DUTY, n.  That which sternly impels us in the direction of profit,
along the line of desire.

    Sir Lavender Portwine, in favor at court,
    Was wroth at his master, who'd kissed Lady Port.
    His anger provoked him to take the king's head,
    But duty prevailed, and he took the king's bread,
            Instead.
                                                                  G.J.
    

DUTY, natural law. A human action which is, exactly conformable to the laws 
which require us to obey them. 
     2. It differs from a legal obligation, because a duty cannot always be 
enforced by the law; it is our duty, for example, to be temperate in eating, 
but we are under no legal obligation to be so; we ought to love our 
neighbors, but no law obliges us to love them. 
     3. Duties may be considered in the relation of man towards God, towards 
himself, and towards mankind. 1. We are bound to obey the will of God as far 
as we are able to discover it, because he is the sovereign Lord of the 
universe who made and governs all things by his almighty power, and infinite 
wisdom. The general name of this duty is piety: which consists in 
entertaining just opinions concerning him, and partly in such affections 
towards him, and such, worship of him, as is suitable to these opinions. 
     4.-2. A man has a duty to perform towards himself; he is bound by the 
law of nature to protect his life and his limbs; it is his duty, too, to 
avoid all intemperance in eating and drinking, and in the unlawful 
gratification of all his other appetites. 
     5.-3. He has duties to perform towards others. He is bound to do to 
others the same justice which he would have a right to expect them to do to 
him.
