Man, by his nature, cannot refrain from generalizing; he cannot live moment by moment, without context, without past or future; he cannot eliminate his integrating capacity, i.e., his conceptual capacity, and confine his consciousness to an animal’s perceptual range. Just as an animal’s consciousness cannot be stretched to deal with abstractions, so man’s consciousness cannot be shrunk to deal with nothing but immediate concretes. The enormously powerful integrating mechanism of man’s consciousness is there at birth; his only choice is to drive it or to be driven by it. Since an act of volition—a process of thought—is required to use that mechanism for a cognitive purpose, man can evade that effort. But if he evades, chance takes over: the mechanism functions on its own, like a machine without a driver; it goes on integrating, but integrating blindly, incongruously, at random
