It still would be years before I understood the seriousness of my change of view. Much later, I recognized it in "Revolution," the essay of Polish journalist Ryszard Kapuscinski, who describes the moment when a man on the edge of a crowd looks back defiantly at a policeman — and when that policeman senses a sudden refusal to accept his defining gaze — as the imperceptible moment in which rebellion is born. "All books about all revolutions begin with a chapter that describes the decay of tottering authority or the misery and sufferings of the people," Kapuscinski writes. "They should begin with a psychological chapter — one that shows how a harassed, terrified man suddenly breaks his terror, stops being afraid. This unusual process — sometimes accomplished in an instant, like a shock — demands to be illustrated. Man gets rid of fear and feel free. Without that, there would be no revolution. ↗
Random mutations much more easily debilitate genes than improve them, and that this is true even of the helpful mutations. Let me emphasize, our experience with malaria’s effects on humans (arguably our most highly studied genetic system) shows that most helpful mutations degrade genes. What’s more, as a group the mutations are incoherent, meaning that they are not adding up to some new system. They are just small changes - mostly degradative - in pre-existing, unrelated genes. The take-home lesson is that this is certainly not the kind of process we would expect to build the astonishingly elegant machinery of the cell. If random mutation plus selective pressure substantially trashes the human genome, why should we think that it would be a constructive force in the long term? There is no reason to think so. ↗

So it’s democracy versus capitalism at this point, friends, and we out on this frontier outpost of the human world are perhaps better positioned than anyone else to see this and to fight this global battle, there’s empty land here, there’s scarce and nonrenewable resources here, and we’re going to get swept up into the fight and we cannot choose not to be part of it, we are one of the prizes and our fate will be decided by what happens throughout the human world. That being the case, we had better band together for the common good, for Mars and for us and for all the people on earth and for the seven generations, it’s going to be hard it’s going to take years, and the stronger we are the better our chances, which is why I’m so happy to see that burning meteor in the sky pumping the matrix of life into our world, and why I’m so happy to see you all here to celebrate it together, a representative congress of all that I love in this world, but look I think that steel-drum band is ready to play aren’t you” (shouts of assent) “so why don’t you folks start and we’ll dance till dawn and tomorrow scatter on the winds and down the sides of this great mountain, to carry the gift everywhere. ↗
There will come a time,' I said, 'when all of us are dead. All of us. There will come a time when there are no human beings remaining to remember that anyone ever existed or that our species ever did anything. There will be no one left to remember Aristotle or Cleopatra, let alone you. Everything that we did and built and wrote and thought and discovered will be forgotten and all of this' - I gestured encompassingly - 'will have been for naught. Maybe that time is coming soon and maybe it is millions of years away, but even if we survive the collapse of our sun, we will not survive forever. There was time before organisms experienced consciousness, and there will be time after. And if the inevitability of human oblivion worries you, I encourage you to ignore it. God knows that's what everyone else does. ↗
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. ↗
