While it is true that grazing animals can browse as they require, they enjoy the possibility as well of moving to another location when a food supply is depleted, or of fleeing when threatened by a predator. Hunter and hunted alike are obligated to discrete actions requiring decisions. Relations within the organism may be largely analog, but relations with the world have inevitable digital aspects, because the creature is itself a unit. Information concerning the world must be organized to facilitate choices required by the mandate to act in the interest of survival. But the amount of information presented by a situation depends on how the situation is digitized.
More information is required to pinpoint the time more exactly.
If time can be indefinitely divided, the amount of information required for infinite precision would be infinite. In practice, there is a tradeoff between speed and accuracy. All these choices were set aside in order to formulate what he considered the pressing matter. In order that choices can be made between broad categories, irrelevant details ignored, cognitive processes bracket together masses of information, thus reducing the information load on the organism. In this way, we recognize the half-dozen colors of the rainbow out of the continuum of visible wavelengths, sort out domestic plants from a background of weeds, find people likeable or dislikeable.
