Context

“The material diversity of human acts is infinite. It is not thus that duties differ, but by their formal diversity which results from diverse species of acts, and in this way human acts are not infinite. Reply Obj. 2: Life is predicated of a thing absolutely: wherefore diversity of lives results from a diversity of acts which are becoming to man considered in himself. But efficiency, whence we have the word "office" (as stated above) , denotes action tending to something else according to Metaph. ix, text. 16 [*Ed. Did. viii, 8] . Hence offices differ properly in respect of acts that are referred to other persons;” source
