For twenty-five years I've been speaking and writing in defense of your right to happiness in this world, condemning your inability to take what is your due, to secure what you won in bloody battles on the barricades of Paris and Vienna, in the American Civil War, in the Russian Revolution. Your Paris ended with Petain and Laval, your Vienna with Hitler, your Russia with Stalin, and your America may well end in the rule of the Ku Klux Klan! You've been more successful in winning your freedom than in securing it for yourself and others. This I knew long ago. What I did not understand was why time and again, after fighting your way out of a swamp, you sank into a worse one. Then groping and cautiously looking about me, I gradually found out what has enslaved you: YOUR SLAVE DRIVER IS YOU YOURSELF. No one is to blame for your slavery but you yourself. No one else, I say! ↗
As in the political sphere, the child is taught that he is free, a democrat, with a free will and a free mind, lives in a free country, makes his own decisions. At the same time he is a prisoner of the assumptions and dogmas of his time, which he does not question, because he has never been told they exist. By the time a young person has reached the age when he has to choose (we still take it for granted that a choice is inevitable) between the arts and the sciences, he often chooses the arts because he feels that here is humanity, freedom, choice. He does not know that he is already moulded by a system: he does not know that the choice itself is the result of a false dichotomy rooted in the heart of our culture. Those who do sense this, and who don't wish to subject themselves to further moulding, tend to leave, in a half-unconscious, instinctive attempt to find work where they won't be divided against themselves. With all our institutions, from the police force to academia, from medicine to politics, we give little attention to the people who leave—that process of elimination that goes on all the time and which excludes, very early, those likely to be original and reforming, leaving those attracted to a thing because that is what they are already like. A young policeman leaves the Force saying he doesn't like what he has to do. A young teacher leaves teaching, here idealism snubbed. This social mechanism goes almost unnoticed—yet it is as powerful as any in keeping our institutions rigid and oppressive. ↗
Evolution has no foresight. Complex machinery develops its own agendas. Brains — cheat. Feedback loops evolve to promote stable heartbeats and then stumble upon the temptation of rhythm and music. The rush evoked by fractal imagery, the algorithms used for habitat selection, metastasize into art. Thrills that once had to be earned in increments of fitness can now be had from pointless introspection. Aesthetics rise unbidden from a trillion dopamine receptors, and the system moves beyond modeling the organism. It begins to model the very process of modeling. It consumes evermore computational resources, bogs itself down with endless recursion and irrelevant simulations. Like the parasitic DNA that accretes in every natural genome, it persists and proliferates and produces nothing but itself. Metaprocesses bloom like cancer, and awaken, and call themselves I. ↗
The male frog, in mating season," said Crake, "makes as much noise as it can. The females are attracted to the male frog with the biggest, deepest voice because it suggests a more powerful frog, one with superior genes. Small male frogs - it's been documented - discover that if they position themselves in empty drainpipes, the pipe acts as a voice amplifier, and the small frog appears much larger than it really is." "So?" "So that's what art is, for the artist," said Crake. "An empty drainpipe. An amplifier. A stab at getting laid." "Your analogy falls down when it comes to female artists," said Jimmy. "They're not in it to get laid. They'd gain no biological advantage from amplifying themselves, since potential mates would be deterred rather than attracted by this sort of amplification. Men aren't frogs, they don't want women who are ten times bigger than them." "Female artists are biologically confused," said Crake. ↗
Prediction in a complex world is a chancy business. Every decision that a survival machine takes is a gamble, and it is the business of genes to program brains in advance so that on average they take decisions that pay off. The currency used in the casino of evolution is survival, strictly gene survival, but for many purposes individual survival is a reasonable approximation. ↗
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. ↗
