"By turning my head slightly, I could see something out of the corner of my eye: it was a hand, the small white hand which slid along the table a little while ago. Now it was resting on its back, relaxed, soft and sensual, it had the indolent nudity of a woman sunning herself after bathing. A brown hairy object approached it, hesitant. It was a thick finger, yellowed by tobacco; inside this hand it had all the grossness of a male sex organ. It stopped for an instant, rigid, pointing at the fragile palm, then suddenly, it timidly began to stroke it. I was not surprised, I was only furious at the Self-Taught Man (L'Autodidacte); couldn't he hold himself back, the fool, didn't he realize the risk he was running? The Self-Taught Man did not look surprised. He must have been expecting this for years. He must have imagined what would happen a hundred times, the day the Corsican would slip up behind him and a furious voice would resound suddenly in his ears. Yet he came back every evening, he feverishly pursued his reading and then, from time to time, like a thief, stroked a white hand or perhaps the leg of a small boy. It was resignation that I read on his face."
