It was, when calmly considered, eminently absurd. To see one so young, and by his conversation so highly cultured and intelligent, condemned to early helplessness, his food cut up for him by a servant, as if he were a child, naturally engaged pity, and, on the first day, I cudgeled my brains during the greater part of dinner in the effort to account for his lost arm. He was obviously not a military man; the unmistakable look and stoop of a student told that plainly enough. Nor was the loss one dating from early life: he used his left arm too awkwardly for the event not to have had a recent date. Had it anything to do with his melancholy? Here was a topic for my vagabond imagination, and endless were the romances woven by it during my silent dinner. For the reader must be told of one peculiarity in me, because to it much of the strange complications of my story are due; complications into which a mind less active in weaving imaginary hypotheses to interpret casual and trifling facts would never have been drawn. From my childhood I have been the victim of my constructive imagination, which has led me into many mistakes and some scrapes; because, instead of contenting myself with plain, obvious evidence, I have allowed myself to frame hypothetical interpretations, which, to acts simple in themselves, and explicable on ordinary motives, render the simple-seeming acts portentous. With bitter pangs of self-reproach I have at times discovered that a long and plausible history constructed by me, relating to personal friends, has crumpled into a ruin of absurdity, by the disclosure of the primary misconception on which the whole history was based. I have gone, let us say, on the supposition that two people were secretly lovers; on this supposition my imagination has constructed a whole scheme to explain certain acts, and one fine day I have discovered indubitably that the supposed lovers were not lovers, but confidants of their passions in other directions, and, of course, all my conjectures have been utterly false. The secret flush of shame at failure has not, however, prevented my falling into similar mistakes immediately after.
