If the excellent Betteredge had been present while I was considering that question, and if he had been let into the secret of my thoughts, he would, no doubt, have declared that the German side of me was, on this occasion, my uppermost side. To speak seriously, it is perhaps possible that my German training was in some degree responsible for the labyrinth of useless speculations in which I now involved myself. For the greater part of the night, I sat smoking, and building up theories, one more profoundly improbable than another. When I did get to sleep, my waking fancies pursued me in dreams. I rose the next morning, with Objective-Subjective and Subjective-Objective inextricably entangled together in my mind; and I began the day which was to witness my next effort at practical action of some kind, by doubting whether I had any sort of right (on purely philosophical grounds) to consider any sort of thing (the Diamond included) as existing at all.
