doctrine which conflicts with popular belief as to one, does so also with regard to the other.
So far we have seen that subjection to a moral tribunal lies at the bottom of our answering for our deeds. The vulgar understand that we answer; that we answer not for everything, but only for what is ours; or, in other words, for what can be imputed to us. If now we can say what is commonly presupposed by imputability, we shall have accomplished the first part of our undertaking, by the discovery of what responsibility means for the people. And at this point again we must repeat our caution to the reader, not to expect from us either law or systematic metaphysics; and further to leave out of sight the slow historical evolution of the idea in question. We have one thing to do, and one only, at present—to find what lies in the mind of the ordinary man.
Now the first condition of the possibility of my guiltiness, or of my becoming a subject for moral imputation, is my self-sameness; I must be throughout one identical person. We do say, ‘He is not the same man that he was,’ but always in another sense, to signify that the character or disposition of the person is altered. We never mean by it, ‘He is not the same person,’ strictly; and, if that were our meaning, then we (the non-theoretical) should also believe, as a consequence, that the present person could not rightly be made to answer for what (not his self, but) another self had done. If, when we say, ‘I did it,’ the I is not to be the one I, distinct from all other I’s; or if the one I, now here, is not the same I with the I, whose act the deed was, then there can be no question whatever but that the ordinary notion of responsibility disappears.
In the first place, then, I must be the very same person to whom the deed belonged; and, in the second place, it must have belonged to me—it must have been mine. What then is it which makes a deed mine? The question has been often discussed, and it is not easy to answer it with scientific accuracy; but here we are concerned simply with the leading features of the ordinary notion. And the first of these is, that we must have an act, and not something which can not be called by that name. The deed must issue from my will; in Aristotle’s language, the ἀρχή must be in myself. Where I am forced, there I do nothing.
