"Past and future are but two aspects of behavior, the past being the persistent modifications in the behaving organism, and the future the controlling direction or pattern imposed upon the unfolding behavior according to those persistent modifications."

“The most important things about the individual are what he cannot or will not say.”

“A policy therefor might be likened to strategy, the broad, overall, long term conception which gives direction and purpose to the tactics of immediately daily operations and decisions.”

“The concept of teleological mechanisms, however it be expressed in many terms, may be viewed as an attempt to escape from these older mechanistic formulations that now appear inadequate, and to provide new and more fruitful conceptions and more effective methodologies for studying self-regulating processes, self-orienting systems and organisms, and self-directing personalities. Thus, the terms feedback, servomechanisms, circular systems, and circular processes may be viewed as different but equivalent expressions of much the same basic conception”

“The concepts of purposive behavior and teleology have long been associated with a mysterious, self-perfecting or goal-seeking capacity or final cause, usually of superhuman or super-natural origin. To move forward to the study of events, scientific thinking had to reject these beliefs in purpose and these concepts of teleological operations for a strictly mechanistic and deterministic view of nature. This mechanistic conception became firmly established with the demonstration that the universe was based on the operation of anonymous particles moving at random, in a disorderly fashion, giving rise, by their multiplicity, to order and regularity of a statistical nature, as in classical physics and gas laws. The unchallenged success of these concepts and methods in physics and astronomy, and later in chemistry, gave biology and physiology their major orientation. This approach to problems of organisms was reinforced by the analytical preoccupation of the Western European culture and languages. The basic assumptions of our traditions and the persistent implications of the language we use almost compel us to approach everything we study as composed of separate, discrete parts or factors which we must try to isolate and identify as potential causes. Hence, we derive our preoccupation with the study of the relation of two variables. We are witnessing today a search for new approaches, for new and more comprehensive concepts and for methods capable of dealing with the large wholes of organisms and personalities.”

“We are living the events which for centuries to come will be minutely studied by scholars who will undoubtedly describe these days as probably the most exciting and creative in the history of mankind. But preoccupied with our daily chores, our worries and personal hopes and ambitions, few of us are actually living in the present.”

“We exist in the geographical environment, moving about in space-time, as we carry on our continual intercourse with nature, through breathing, drinking, eating, absorbing light, heat and other forms of radiant energy, eliminating through breathing, urination and defecation, through the skin and by radiation of heat, as the geographical environment flows in and out of us, as it does in all other organisms.”
