Cora May Williams, A Review of the Systems of Ethics Founded on the Theory of Evolution
“ Obligation "expresses that an act is the act required." "It is that relation in which the single part of the order stands to the whole order, when it is confronted by the whole," whether we consider the single act in relation to the whole character of the individual, or the single individual in his relations to society. "Duty in the abstract is the name which comprehends obligation in all its details; a duty in the concrete is any good act regarded in its relation to the whole. ”
