Met. I am of the contrary opinion for the very same reason. But that does not matter. Give me your attention for a moment. I deny that life itself, i.e., the mere sensation of existence, has anything pleasurable or desirable in its nature. But we all wish for the other thing, also called life; I mean strength, and numerous sensations. Thus, all activity, and every strong and lively passion, provided it be neither disagreeable nor painful, pleases us simply because it is strong and lively, although it possess no other pleasurable attributes.
Now these men, whose life normally lasts only forty years, that is, half the time granted by nature to other men, would experience every moment an intensity of life, twice as strong as ours, because their growth, maturity, and decline are accomplished twice as rapidly as with us. Their energy of life therefore ought to be twice as intense as ours at every moment of their existence. And to this greater intensity there must correspond a more lively activity of the will, more vivacity and animation. Thus they experience in less time the same quantity of life as we have. And the fewer years that these favoured people spend on the earth are so well filled that there is no sensible vacuum; whereas this same quantity of life is insufficient to vivify a term twice as long. Their actions and sensations, diffused over so limited a space, can duly occupy all their existence; but our longer life is constantly divided by protracted intervals devoid of all activity and lively passion. And since existence itself is in no sense desirable, but only in so far as it is happy; and since good or evil fortune is not measurable by the number of our days; I conclude that the life of these people, though shorter than ours, is much the richer in pleasures, or what are so called. Their life must then be preferable to ours, or even to that of the earliest kings of Assyria, Egypt, China, India, and other countries, who are said to have lived thousands of years. So that, far from being desirous of immortality, I am content to leave it to fishes, which are by Leeuwenhoek believed to be immortal, provided they are neither eaten by us nor their fellows. Instead of delaying the development of the body, in order to lengthen life, as Maupertuis[4] proposed, I would rather accelerate it until the duration of our life was as short as that of the insects called ephemerals; which insects, although the most aged does not live beyond a single day, nevertheless preside over three generations before they die. If it were so, then there would at least be no time for ennui.
What do you think of my reasoning?
Nat. Phil. It does not persuade me. I know that you love metaphysics, whereas I for my part hold to physics. To your subtleties, I oppose simple common sense, which is sufficient for me. Thus, I venture to assert, without appealing to the microscope, that life is better than death. Judging between the two, I would give the apple to the former, without troubling them to strip for the contest.
Met. And I would do the same. But when I call to mind the custom of those barbarians, who, for every unhappy day of their lives, used to throw a black stone into a quiver, and for every happy day a white one, I cannot help thinking how few white stones compared to the black ones would be found therein on the death of the proprietor of the quiver. Personally, I should like to have now all the stones representing the days of life yet remaining to me, and permission to separate them, throwing away all-the black ones and retaining only those that were white; even though the number of the latter was exceedingly small, and their colour a doubtful white.
Nat. Phil. Many people, on the contrary, would be glad to increase the number of their black stones, even though they were blacker than they naturally would be; because they always, in their minds, dread the last as the blackest of all. And such people, of whom I am one, will really be able to add many stones to their normal quantity, if they follow out the instructions contained in my book.
Met. Every one thinks and works in his own way. Death also will not fail to do the same. But if you wish, in prolonging man's life; really to be of service to him, discover an art to increase the number and strength of sensations, and their effects. This would be a genuine augmentation of human life, for it would fill up those long intervals of time, during which we vegetate rather than live. You could then boast of having truly prolonged human life; and without having sought after the impossible, or used violence to natural laws; rather, by having strengthened them. For does it not seem as though the ancients were more full of life than we are, in spite of the many and great dangers by which they were surrounded, and which generally shortened their existence?
You will thus render a real service to man, whose life is, I will not say more happy, but certainly less unhappy, when it is better occupied and more violently agitated, without pain or discomfort. When, on the other hand, existence is so full of idleness and ennui as to be justly termed empty, the saying of Pyrrhus, "there is no difference between life and death," is literally realised. Were this saying true, I should be in no slight terror of death.
But finally, unless life be active and vigorous, it is not true life, and death is far preferable to it.
