The first speaker smiled compassionately, and perhaps also a little patronizingly. "I'm not sure that you have met the point exactly. Metchnikoff denies, on the basis of scientific knowledge, that it is possible for a man, being dead, to live again. In those two extremely interesting chapters of his, which treat of the 'Religious Remedies' and the 'Philosophical Remedies' for the 'disharmonies of the human constitution,' he is quite as unsparing of the sages as of the saints. The Christians and the Buddhists fare no worse than Plato and the Stoics; the last are no less unscientific than the first in his view, and no less fallacious. What he asks is not that we shall be resigned or enraptured in view of death, but that we shall physically desire it when we are tired of living, just as we physically desire sleep when we are tired of waking." "And to that end," the light skirmisher said, "he asks nothing but that we shall live a hundred and fifty years." "No, he asks that we shall live such natural lives that we shall die natural deaths, which are voluntary deaths. He contends that most of us now die accidental and violent deaths." The woman who had caught on demanded, "Why does he think we could live a century and a half?" "From analogies in the lives of other animals and from the facts of our constitution. He instances the remarkable cases of longevity recorded in the Bible." "I think he's very inconsistent," his pursuer continued. "The Bible says men lived anywhere from a hundred to nine hundred years, and he thinks it quite possible. The Bible says that men live after death, and he thinks that's impossible." "Well, have you ever met a man who had lived after death?" the first speaker asked. "No. Have you ever met a man two hundred years old? If it comes to undeniable proof there is far more proof of ghosts than of bicentenarians." "Very well, then, I get out of it by saying that I don't believe in either." "And leave Metchnikoff in the lurch!" the light skirmisher reproached him. "You don't believe in the instinct of death! And I was just going to begin living to a hundred and fifty and dying voluntarily by leaving off cheese. Now I will take some of the Gorgonzola." Everybody laughed but the first speaker and the woman who had caught on; they both looked rather grave, and the closest listener left off laughing soonest. "We can't be too grateful to science for its devotion to truth. But isn't it possible for it to overlook one kind of truth in looking for another? Isn't it imaginable that when a certain anthropoid ape went wrong and blundered into a man, he also blundered into a soul, and as a slight compensation for having involuntarily degenerated from his anthropoid ancestor, came into the birthright of eternal life?" "It's imaginable," the first speaker granted. "But science leaves imagining things to religion and philosophy."
