It is truly absurd for a man to attribute his actions to external things instead of to his own capacity for being easily caught by them;[1] or, again, to ascribe the honourable to himself, and the base ones to pleasure. So then that seems to be compulsory “whose origination is from without, the party compelled contributing nothing.” Chapter II. Now every action of which ignorance is the cause is not-voluntary, but that only is involuntary which is attended with pain and remorse; for clearly the man who has done anything by reason of ignorance, but is not annoyed at his own action, cannot be said to have done it _with_ his will because he did not know he was doing it, nor again _against_ his will because he is not sorry for it. So then of the class “acting by reason of ignorance,” he who feels regret afterwards is thought to be an involuntary agent, and him that has no such feeling, since he certainly is different from the other, we will call a not-voluntary agent; for as there is a real difference it is better to have a proper name. Again, there seems to be a difference between acting _because of_ ignorance and acting _with_ ignorance: for instance, we do not usually assign ignorance as the cause of the actions of the drunken or angry man, but either the drunkenness or the anger, yet they act not knowingly but with ignorance. Again, every bad man is ignorant what he ought to do and what to leave undone, and by reason of such error men become unjust and wholly evil. Again, we do not usually apply the term involuntary when a man is ignorant of his own true interest;[2] because ignorance which affects moral choice[3] constitutes depravity but not involuntariness: nor does any ignorance of principle (because for this men are blamed) but ignorance in particular details, wherein consists the action and wherewith it is concerned, for in these there is both compassion and allowance, because he who acts in ignorance of any of them acts in a proper sense involuntarily. It may be as well, therefore, to define these particular details; what they are, and how many; viz. who acts, what he is doing, with respect to what or in what, sometimes with what, as with what instrument, and with what result;[4] as that of preservation, for instance, and how, as whether softly or violently.
