“The existence of analogies between central features of various theories implies the existence of a general theory which underlies the particular theories and unifies them with respect to those central features. This fundamental principle of generalization by abstraction was enunicated by the eminent American mathematician E. H. Moore more than thirty years ago. It is the purpose of the pages that follow to work out its implication for theoretical and applied economics.”

“Theory in the social sciences should have three major functions. First, it should aid in the codification of our existing concrete knowledge. It can do so by providing generalized hypotheses for the systematic reformulation of existing facts and insights, by extending the range of implication of particular hypotheses, and by unifying discrete observations under general concepts. Through codification, general theory in the social sciences will help to promote the process of cumulative growth of our knowledge. In making us more aware of the interconnections among items of existing knowledge which are now available in a scattered, fragmentary form, it will help us fix our attention on the points where further work must be done.
Second, general theory in the social sciences should be a guide to research. By codification it enables us to locate and define more precisely the boundaries of our knowledge and of our ignorance. Codification facilitates the selection of problems, although it is not, of course, the only useful technique for the selection of problems for fruitful research. Further than this, general theory should provide hypotheses to be applied and tested by the investigation of these problems…
Third, general theory as a point of departure for specialized work in the social sciences will facilitate the control of the biases of observation and interpretation which are at present fostered by the departmentalization of education and research in the social sciences.”

“(a) There is a general tendency towards integration in the various sciences, natural and social. (b) Such integration seems to be centered in a general theory of systems. (c) Such theory may be an important means of aiming at exact theory in the nonphysical fields of science. (d) Developing unifying principles running "vertically" through the universe of the individual sciences, this theory brings us nearer to the goal of the unity of sciences. (e) This can lead to a much needed integration in scientific education.”

Ludwig von Bertalanffy (1901–1972) austrian biologist and philosopher

Variant: Mayor aims of general theory:
(1) There is a general tendency toward integration in the various sciences, natural and social.
(2) Such integration seems to be centered in a general theory of systems.
(3) Such theory may be an important means for aiming at exact theory in the nonphysical fields of science.
(4) Developing unifying principles running "vertically" through the universe of the individual sciences, this theory brings us nearer the goal of the unity of science.
(5) This can lead to a much-needed integration in scientific education.

“No matter how abstractly formulated are a general theory of systems, a general theory of evolution and a general theory of communication, all three theoretical components are necessary for the specifically sociological theory of society. They are mutually interdependent.”
