To put it bluntly but fairly, anyone today who doubts that the variety of life on this planet was produced by a process of evolution is simply ignorant—inexcusably ignorant, in a world where three out of four people have learned to read and write.
These considerations lead to the postulate of a new scientific discipline which we call general system theory. It's subject matter is formulation of principles that are valid for "systems" in general, whatever the nature of the component elements and the relations or "forces" between them.
The opposition is indispensable. A good statesman, like any other sensible human being, always learns more from his opponents than from his fervent supporters. For his supporters will push him to disaster unless his opponents show him where the dangers are. So if he is wise he will often pray to be delivered from his friends, because they will ruin him. But, though it hurts, he ought also to pray never to be left without opponents; for they keep him on the path of reason and good sense.
In our considerations we started with a general definition of "systems" defined as a "set of elements standing in interrelations... No special hypothesis or statement were made about the nature of the system, of its elements or the relations between them. Nevertheless from this purely formal definition of "system" many properties follow which in part are expressed in laws well-known in various fields of science, and in part concern concepts previously regarded as anthropomorphic, vitalistic. or metaphysical. The parallelism of general conceptions or even special laws in different fields therefore is a consequence of the fact that those are concerned with "systems" and that certain general principles apply to systems irrespective of their nature.
Concepts like those of organization, wholeness, directiveness, teleology, control, self-regulation, differentiation, and the like are alien to conventional science. However, they pop up everywhere in the biological, behavioral, and social sciences and are, in fact, indispensable for dealing with living organisms or social groups. Thus, a basic problem posed to modem science is a general theory of organization. General Systems Theory is, in principle, capable of giving exact definitions for such concepts.
If I am only happy for myself, many fewer chances for happiness. If I am happy when good things happen to other people, billions more chances to be happy!
Whatever we may say will not be the objective level, which remains fundamentally un-speakable. Thus, we can sit on the object called 'a chair', but we cannot sit on the noise we made or the name we applied to that object.
General system theory, therefore, is a general science of "wholeness...The meaning of the somewhat mystical expression, "The whole is more that the sum of its parts" is simply that constitutive characteristics are not explanable from the characteristics of the isolated parts. The characteristics of the complex, therefore, appear as "new" or "emergent.
