[Another significant aspect of the concept of growth is the distinction that Mesarovic and Pestel draw between "undifferentiated" and "organic" growt… - Mihajlo D. Mesarovic

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.

We found that technological optimism is the common and the most dangerous reaction to our findings... Technology can relieve the symptoms of the problem without affecting the underlying causes. Faith in technology as the ultimate solution to all problems can thus divert our attention from the most fundamental problem— the problem of growth in a finite system- and prevent us from taking effective action to solve it... We would deplore an unreasoned rejection of the benefits of technology as strongly as we argue here against an unreasoned acceptance of them. Perhaps the best summary of our position is the motto of the Sierra Club; not blind opposition to progress but opposition to blind progress.
Taking no action to solve these problems is equivalent of taking strong action. Every day of continued exponential growth brings the world system closer to the ultimate limits of that growth. A decision to do nothing is a decision to increase the risk of collapse.
The way to proceed is clear... [we possess] all that is necessary to create a totally new form of human society... the two missing ingredients are the realistic long-term goal... and the human will to achieve that goal.

General systems theory deals with the most fundamental concepts and aspects of systems. Many theories dealing with more specific types of systems (e.g., dynamical systems, automata, control systems, game-theoretic systems, among many others) 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 (which are based on special mathematical structures such as differential or difference equations, numerical or abstract algebras, etc.) 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.
