Alexander Bain,
Moral Science; a Compendium of Ethics
“ A command is the signification of a desire or wish, accompanied with the power and the purpose to inflict evil if that desire is not complied with. The person so desired is bound or obliged, or placed under a duty, to obey. Refusal is disobedience, or violation of duty. The evil to be inflicted is called a sanction, or an enforcement of obedience; the term punishment expresses one class of sanctions. ”
