“Shall we not perhaps be told, on the other hand, that if the sinner suffers an eternal punishment, it is because he does not cease to sin? — for the damned sin without ceasing. This however is no solution to the problem, which derives all its absurdity from the fact that punishment has been conceived as vindictiveness or vengeance, not as correction, and has been conceived after the fashion of barbarous peoples. And in the same way hell has been conceived as a sort of police institution, necessary in order to put fear into the world. And the worst of it is that it no longer intimidates, and therefore will have to be shut up.”

From ‘’Justice’’ in Unspoken Sermons Series III (1889)
Context: If sin must be kept alive, then hell must be kept alive; but while I regard the smallest sin as infinitely loathsome, I do not believe that any being, never good enough to see the essential ugliness of sin, could sin so as to deserve such punishment. I am not now, however, dealing with the question of the duration of punishment, but with the idea of punishment itself; and would only say in passing, that the notion that a creature born imperfect, nay, born with impulses to evil not of his own generating, and which he could not help having, a creature to whom the true face of God was never presented, and by whom it never could have been seen, should be thus condemned, is as loathsome a lie against God as could find place in heart too undeveloped to understand what justice is, and too low to look up into the face of Jesus.
