This proposition is a consequence of the foregoing; for if the law can only command the maxim of the actions, not the actions themselves, this is a sign that it leaves in the observance of it a latitude (latitudo) for the elective will; that is, it cannot definitely assign how and how much we should do by the action towards the end which is also duty. But by an indeterminate duty is not meant a permission to make exceptions from the maxim of the actions, but only the permission to limit one maxim of duty by another (e. g., the general love of our neighbour by the love of parents); and this in fact enlarges the field for the practice of virtue. The more indeterminate the duty, and the more imperfect accordingly the obligation of the man to the action, and the closer he nevertheless brings this maxim of obedience thereto (in his own mind) to the strict duty (of justice), so much the more perfect is his virtuous action.

Hence it is only imperfect duties that are duties of virtue. The fulfilment of them is merit (meritum) = + a; but their transgression is not necessarily demerit (demeritum) = - a, but only moral unworth = o, unless the agent made it a principle not to conform to those duties. The strength of purpose in the former case is alone properly called virtue [Tugend] (virtus); the weakness in the latter case is not vice (vitium), but rather only lack of virtue [Untugend], a want of moral strength (defectus moralis). (As the word Tugend is derived from taugen [to be good for something], Untugend by its etymology signifies good for nothing.) Every action contrary to duty is called transgression (peccatum). Deliberate transgression which has become a principle is what properly constitutes what is called vice (vitium).

Although the conformity of actions to justice (i.e., to be an upright man) is nothing meritorious, yet the conformity of th............
