Survival machines that can simulate the future are one jump ahead of survival machines who can only learn on the basis of overt trial and error. The trouble with overt trial is that it takes time and energy. The trouble with overt error is that it is often fatal. Simulation is both safer and faster. The evolution of the capacity to simulate seems to have cumulated in subjective consciousness.

You don't have to be a scientist – you don't have to play the Bunsen burner – in order to understand enough science to overtake your imagined need and fill that fancied gap. Science needs to be released from the lab into the culture.

Why would anybody be intimidated by mere words? I mean, neither I nor any other athiest that I know ever threatens violence. We never threaten to fly planes into skyscrapers. We never threaten suicide bombs. We are very gentle people. All we do is use words to talk about things like the cosmos, the origin of the universe, evolution, the origin of life. What's there to be frightened of? It's just an opinion.

Wild animals almost never die of old age: starvation, disease, or predators catch up with them long before they become really senile. Until recently this was true of man too. Most animals die in childhood, many never get beyond the egg stage. Starvation and other causes of death are the ultimate reasons why populations cannot increase indefinitely.
