In defining systems theory, I review the key ideas of Bertalanffy and Boulding, who were The first part of this chapter is a review of the evolution two of the founders of the Society for the Advancement of of the systems movement and a discussion of human sys- General Systems Theory.

Systems inquiry incorporates three interrelated domains 3.1.1.1.1. Bertalanffy (1956, pp. 1—10). He suggested of disciplined inquiry: systems theory, systems philosophy, that “modem science is characterized by its ever-increasing and systems methodology. Bertalanffy (1968) notes that in specialization, necessitated by the enormous amount of data, contrast with the analytical, reductionist, and linear-causal the complexity of techniques, and structures within every paradigm of classical science, systems philosophy brings forth field. This, however, led to a breakdown of science as an a reorientation of thought and world view, manifested by an integrated realm. “Scientists, operating in the various dis- expansionist, nonlinear dynamic, and synthetic mode of ciplines, are encapsulated in their private universe, and it is thinking.

They came from a variety of disciplines and fields structural similarities or isomorphies in different fields: of study. They shared and articulated a common conviction: the unified nature of reality. They recognized a compelling There are correspondences in the principles which govern need for a unified disciplined inquiry in understanding and the behavior of entities that are intrinsically widely different. dealing with increasing complexities, complexities that are These correspondences are due to the fact that they all can be considered, in certain aspects, “systems,” that is, complexes beyond the competence of any single discipline.

In contrast, the The two papers introduced above set forth the vision of educational demands of scientific generalists and developing the systems movement. That vision still guides us today. At transdisciplinary basic principles are precisely those that this point it seems to be appropriate to tell the story that marks General Systems Theory (GST) tries to fill. In this sense, the genesis of the systems movement.
