"There is a much more subtle and completely novel threat to man's survival that looms, every year more menacingly, beside that of an atomic holocaust; the cluster of world-wide problems - not only material in nature - growing at an incredible speed when viewed in historical perspective, and called by The Club of Rome the "problématique humaine. In fact, we believe that even without the atomic world war, human existence as we know it is threatened if no way can be found to resolve this crisis syndrome."

“Isn't it legitimate to ask, as representatives of the developing countries, whether there should be maximum limits consumption...?”

“General systems theory deals with the most fundamental concepts and aspects of systems. Many theories dealing with more specific types of systems have been under development for quite some time. General systems theory is concerned with the basic issues common to all these specialized treatments. Also, for truly complex phenomena, such as those found predominantly in the social and biological sciences, the specialized descriptions used in classical theories do not adequately and properly represent the actual events. Either because of this inadequate match between the events and types of descriptions available or because of the pure lack of knowledge, for many truly complex problems one can give only the most general statements, which are qualitative and too often even only verbal. General systems theory is aimed at providing a description and explanation for such complex phenomena.”

“To grow or not to grow is neither a well-defined nor a relevant question until the location, sense, and subject of growing and the growth process itself are defined”

“Since it can be argued that both science and engineering are concerned with the study of real systems and their behavior, it follows that a general theory should be concerned with the study of general systems... It suffices for the present discussion to consider a general system as an abstract analogue or model of a class of real systems. General systems theory is then a theory of general models.”

“There is no such concept as one limit for the entice system: rather different parts of the system face different limits at different times with the traumatic experiences for the entire system depending on the interrelationship of the constituent parts - the collapse, if it occurs, would he regional rather than global, even though the entire global system would be affected.”

“involves a process of differentiation, which means that various groups of cells begin to differ in structure and function... During and after differentiation the number of cells can still increase, and the organs grow in size, but while some organs grow, others might celine.”
