        [1913 Webster]
    

IMMORAL, adj.  Inexpedient.  Whatever in the long run and with regard
to the greater number of instances men find to be generally
inexpedient comes to be considered wrong, wicked, immoral.  If man's
notions of right and wrong have any other basis than this of
expediency; if they originated, or could have originated, in any other
way; if actions have in themselves a moral character apart from, and
nowise dependent on, their consequences -- then all philosophy is a
lie and reason a disorder of the mind.
