Human sense organs can receive only news of difference, and the differences must be coded into events in time (i.e., into changes) in order to be perceptible. Ordinary static differences that remain constant for more than a few seconds become perceptible, only by scanning. Similarly, very slow changes become perceptible only by a combination of scanning and bringing together observations from separated moments in the continuum of time.

» Gregory Bateson - all quotes »
Within a certain kind of environment, an activity may be checked so that the only meaning which accrues is of its direct and tangible isolated outcome. One may cook, or hammer, or walk, and the resulting consequences may not take the mind any farther than the consequences of cooking, hammering, and walking in the literal — or physical — sense. But nevertheless the consequences of the act remain far-reaching. To walk involves a displacement and reaction of the resisting earth, whose thrill is felt wherever there is matter. It involves the structure of the limbs and the nervous system; the principles of mechanics. To cook is to utilize heat and moisture to change the chemical relations of food materials; it has a bearing upon the assimilation of food and the growth of the body. The utmost that the most learned men of science know in physics, chemistry, physiology is not enough to make all these consequences and connections perceptible. The task of education, once more, is to see to it that such activities are performed in such ways and under such conditions as render these conditions as perceptible as possible.
John Dewey
Voice is a flowing breath of air, perceptible to the hearing by contact.
Vitruvius
Our initial sensory data are always "first derivatives," statements about differences which exist among external objects or statements about changes which occur either in them or in our relationship to them. Objects and circumstances which remain absolutely constant relative to the observer, unchanged either by his own movement or by external events, are in general difficult and perhaps always impossible to perceive. What we perceive easily is difference and change — and difference is a relationship.
Gregory Bateson
The present is always invisible because its environmental. No environment is perceptible, simply because it saturates the whole field of attention.
Marshall McLuhan
The naturalist is a civilized hunter. He goes alone into the field or woodland and closes his mind to everything but that time and place, so that life around him presses in on all the senses and small details grow in significance. He begins the scanning search for which cognition was engineered. His mind becomes unfocused, it focuses on everything, no longer directed toward any ordinary task or social pleasantry.
