"And what is that?"

"Immortality, of course. Surely you must see by now that all the activities of modern life are really directed towards one end—towards solving the riddle of prolonging life and at the same time increasing pleasure? Isn't that the inner secret desire that you doctors find in every patient? So far a compromise has only been possible, but now that is all changed."

"I don't agree, Sarakoff. Some people must live for other motives. Take myself ... I live for science."

"It is merely your form of pleasure."

"That's a quibble," I cried angrily. "Science is aspiration. There's all the difference in the world between aspiration and pleasure. I have scarcely known what pleasure is. I have worked like a slave all my life, with the sole ambition of leaving something permanent behind me when I die."

"But you won't die," interposed the Russian. "That is the charm of the new situation."

"Then why should I work?" The question shaped itself in my mind and I uttered it involuntarily. I sat down and stared at the fire. A kind of dull depression came over me, and for some reason the picture of Sarakoff's butterflies appeared in my mind. I saw them with great distinctness, crawling aimlessly on the floor of their cage. "Why should I work?" I repeated.

Sarakoff merely shrugged his shoulders and turned away. Questions of that kind did not seem to bother him. His was a nature that escaped the necessity of self-analysis. But I was different, and our conversation had aroused a train of odd thought. What, after all, was it that kept my nose to the grindstone? Why had I slaved incessantly all my life, reading when I might have slept, examining patients when I might have been strolling through meadows, hurrying through meals when I might have eaten at leisure? What was the cause behind all the tremendous activity and feverish haste of modern people? When Sarakoff had said that I would not die, and that therein lay the charm of the new situation, it seemed as if scales had momentarily fallen from my eyes. I beheld myself as something ridiculous, comparable to a hare that persists in dashing along a country lane in front of the headlight of a motor car, when a turn one way or another would bring it to safety. A great uneasiness filled me, and with it came a determination to ignore these new fields of thought that loomed round me—a determination that I have seen in old men when they are faced by the new and contradictory—and I began to force my attention elsewhere. I was relieved when the door opened and my servant entered. She handed me a telegram. It was from Miss Annot, asking me to come to Cambridge at once, as her father was seriously ill. I scribbled a reply, saying I would be down that afternoon.

After the servant had left the room, I remained gazing at the fire, but my depression left me. In place of it I felt a quiet elation, and it was not difficult for me to account for it.

"I was wrong in saying that I had scarcely known what pleasure is," I observed at length, looking up at Sarakoff with a smile. "I must confess to you that there is one factor in my life that gives me great pleasure."
