It was on this night that they had their first quarrel. She was angry with him because he no longer had any pride in his profession. She returned to her complaint of the afternoon, reproaching him for not taking more credit to himself for the cure of Sarteur, and even for the prolongation of Valentin’s life. It was she who now had a passion for his fame. She reminded him of his cures; had he not cured himself? Could he deny the efficacy of his treatment? A thrill ran through him as he recalled the great dream which he had once cherished—to combat debility, the sole cause of disease; to cure suffering humanity; to make a higher, and healthy humanity; to hasten the coming of happiness, the future kingdom of perfection and felicity, by intervening and giving health to all! And he possessed the liquor of life, the universal panacea which opened up this immense hope! Pascal was silent for a moment. Then he murmured: “It is true. I cured myself, I have cured others, and I still think that my injections are efficacious in many cases. I do not deny medicine. Remorse for a deplorable accident, like that of Lafouasse, does not render me unjust. Besides, work has been my passion, it is in work that I have up to this time spent my energies; it was in wishing to prove to myself the possibility of making decrepit humanity one day strong and intelligent that I came near dying lately.

To correct nature, to interfere, in order to modify it and thwart it in its purpose, is this a laudable task? To cure the individual, to retard his death, for his personal pleasure, to prolong his existence, doubtless to the injury of the species, is not this to defeat the aims of nature? And have we the right to desire a stronger, a healthier humanity, modeled after our idea of health and strength? What have we to do in the matter? Why should we interfere in this work of life, neither the means nor the end of which are known to us? Perhaps everything is as it ought to be. Perhaps we should risk killing love, genius, life itself. Remember, I make the confession to you alone; but doubt has taken possession of me, I tremble at the thought of my twentieth century alchemy. I have come to believe that it is greater and wiser to allow evolution to take its course.” He paused; then he added so softly that she could scarcely hear him:
