And the others too were beginning to remark in Swann that abnormal, excessive, shameful and deserved senescence of bachelors, of all those for whom it seems that the great day which knows no morrow must be longer than for other men, since for them it is a void of promise, and from its dawn the moments steadily accumulate without any subsequent partition among offspring.
So - I confess I have been a rake at reading. I have read those things which I ought not to have read, and I have not read those things which I ought to have read, and there is no health in me - if by health you mean an inclusive and coherent knowledge of any body of great literature. I can only protest, like all rakes in their shameful senescence, that I have had a good time.
The wheel of life: one generation rises like summer wheat, then withers and falls to seed. The wheel turns - birth, youth, adulthood, parenthood, senescence, death - driven by genetic machinery set in motion so many eons ago. For all its subtleties and infinite beauty, life has but one purpose: to keep the wheel turning.

Long before there were effective treatments, physicians dispensed prognoses, hope, and, above all, meaning. When something terrible happens-and serious disease is always terrible-people want to know why. In a pantheistic world, the explanation was simple-one god had caused the problem, another could cure it. In the time since people have been trying to get along with only one God, explaining disease and evil has become more difficult. Generations of theologians have wrestled with the problem of theodicy-how can a good God allow such bad things to happen to good people? Darwinian medicine can't offer a substitute for such explanations. It can't provide a universe in which events are part of a divine plan, much less one in which individual illness reflects individual sins. It can only show us why we are the way we are, why we are vulnerable to certain diseases. A Darwinian view of medicine simultaneously makes disease less and more meaningful. Diseases do not result from random or malevolent forces, they arise ultimately from past natural selection. Paradoxically, the same capacities that make us vulnerable to disease often confer benefits. The capacity for suffering is a useful defense. Autoimmune disease is a price of our remarkable ability to attack invaders. Cancer is the price of tissues that can repair themselves. Menopause may protect the interests of our genes in existing children. Even senescence and death are not random, but compromises struck by natural selection as it inexorably shaped out bodies to maximize the transmission of our genes. In such paradoxical benefits, some may find a gentle satisfaction, even a bit of meaning-at least the sort of meaning Dobzhansky recognized. After all, nothing in medicine makes sense except in the light of evolution.
