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.
