It was possible, therefore, to commit a sin without knowing that you committed it, without wanting to commit it, and without being able to avoid it. Sin was not necessarily something that you did: it might be something that happened to you. I do not want to claim that this idea flashed into my mind as a complete novelty at this very moment, under the blows of [school-warden] Sambo's cane: I must have had glimpses of it even before I left home, for my early childhood had not been altogether happy. But at any rate this was the great, abiding lesson of my boyhood: that I was in a world where it was not possible for me to be good. And the double beating was a turning-point, for it brought home to me for the first time the harshness of the environment into which I had been flung. Life was more terrible, and I was more wicked, than I had imagined.
