“Let us say, as a thought experiment, that someone in a country equipped with doomsday weapons fears attack from another country and strikes preemptively. There would be thousands of years of cultural history and some few decades of personal history behind the decision. Madman though he might be, he would have brought the species to a culmination that humankind had been preparing for eons. To say that a spasm of activity in a region of his brain was crucial to the event would be utterly trivial.”
