"Precisely; that is, not at all," replied the doctor.

"You don't mean to say there is no such thing as responsibility, no such thing as justice. Oh, I see, you deny free will. You are a necessitarian."

The doctor waved his hand rather contemptuously.

"I know nothing about your theological distinctions; I am a doctor. I say that there is no such thing as moral responsibility for past acts, no such thing as real justice in punishing them, for the reason that human beings are not stationary existences, but changing, growing, incessantly progressive organisms, which in no two moments are the same. Therefore justice, whose only possible mode of proceeding is to punish in present time for what is done in past time, must always punish a person more or less similar to, but never identical with, the one who committed the offence, and therein must be no justice.

"Why, sir, it is no theory of mine, but the testimony of universal consciousness, if you interrogate it aright, that the difference between the past and present selves of the same individual is so great as to make them different persons for all moral purposes. That single fact we were just speaking of—the fact that no man would care for vengeance on one who had injured him, provided he knew that all memory of the offence had been blotted utterly from his enemy's mind—proves the entire proposition. It shows that it is not the present self of his enemy that the avenger is angry with at all, but the past self. Even in the blindness of his wrath he intuitively recognizes the distinction between the two. He only hates the present man, and seeks vengeance on him in so far as he thinks that he exults in remembering the injury his past self did, or, if he does not exult, that he insults and humiliates him by the bare fact of remembering it. That is the continuing offence which alone keeps alive the avenger's wrath against him. His fault is not that he did the injury, for he did not do it, but that he remembers it.

"It is the first principle of justice, isn't it, that nobody ought to be punished for what he can't help? Can the man of to-day prevent or affect what he did yesterday, let me say, rather, what the man did out of whom he has grown—has grown, I repeat, by a physical process which he could not check save by suicide. As well punish him for Adam's sin, for he might as easily have prevented that, and is every whit as accountable for it. You pity the child born, without his choice, of depraved parents. Pity the man himself, the man of today who, by a process as inevitable as the child's birth, has grown on the rotten stock of yesterday. Think you, that it is not sometimes with a sense of loathing and horror unutterable, that he feels his fresh life thus inexorably knitting itself on, growing on, to that old stem? For, mind you well, the consciousness of the man exists alone in the present day and moment. There alone he lives. That is himself. The former days are his dead, for whose sins, in which he had no part, which perchance by his choice never would have been done, he is held to answer and do penance. And you thought, young man, that there was such a thing as justice !"

"I can see," said Henry, after a pause, "that when half a lifetime has intervened between a crime and its punishment, and the man has reformed, there is a certain lack of identity. I have always thought punishments in such cases very barbarous. I know that I should think it hard to answer for what I may have done as a boy, twenty years ago.

"Yes," said the doctor, "flagrant cases of that sort take the general eye, and people say that they are instances of retribution rather than justice. The unlikeness between the extremes of life, as between the babe and the man, the lad and the dotard, strikes every mind, and all admit that there is not any apparent identity between these widely parted points in the progress of a human organism. How then? How soon does identity begin to decay, and when is it gone—in one year, five years, ten years, twenty years, or how many? Shall we fix fifty years as the period of a moral statute of limitation, after which punishment shall be deemed barbarous? No, no. The gulf between the man of this instant and the man of the last is just as impassable as that between the baby and the man. What is past is eternally past. So far as the essence of justice is concerned, there is no difference between one of the cases of punishment which you called barbarous, and one in which the penalty follows the offence within the hour. There is no way of joining the past with the present, and there is no difference between what is a moment past and what is eternally past."

"Then the assassin as he withdraws the stiletto from his victim's breast is not the same man who plunged it in."

"Obviously not," replied the doctor. "He may be exulting in the deed, or, more likely, he may be in a reaction of regret. He may be worse, he may be better. His being better or worse makes it neither more nor less just to punish him, though it may make it more or less expedient. Justice demands identity; similarity, however close, will not answer. Though a mother could not tell her twin sons apart, it would not make it any more just to punish one for the other's sins."
