Any attempt to reduce the complex properties of biological organisms or of nervous systems or of human brains to simple physical and chemical systems is foolish.

A number of proposals have been advanced in recent years for the development of ‘general systems theory’ which, abstracting from properties peculiar to physical, biological, or social systems, would be applicable to all of them. We might well feel that, while the goal is laudable, systems of such diverse kinds could hardly be expected to have any nontrivial properties in common. Metaphor and analogy can be helpful, or they can be misleading. All depends on whether the similarities the metaphor captures are significant or superficial.
It may not be entirely vain, however, to search for common properties among diverse kinds of complex systems... The ideas of feedback and information provide a frame of reference for viewing a wide range of situations, just as do the ideas of evolution, of relativism, of axiomatic method, and of operationalism... hierarchic systems have some common properties that are independent of their specific content...Herbert Simon
Critical systems thinkers like Gerald Midgley identify three waves of systems thinking over the last 50 years or so. Early systems theorists (e.g. Bertalanffy) described systems in physical terms, resorting to metaphors from electronic computation or biology. This 'hard systems' tradition still has its advocates and practitioners... Subsequently the limits of the physical metaphor... were reached, and the secondwave of systems thinking developed. This 'soft systems thinking' employed social metaphors to develop appropriate systems approaches for human systems. The move to a more phenomenological, interpretative understanding of human systems, where meaning is central and is negotiated intersubjectively, parallels the new paradigm / crisis of social psychology of the 1970s. The Third wave, or critical systems school, in which Midgley locates himself, has drawn on the critical theory of Habermas, particularly in relation to theories of knowledge and of communicative rationality, and on the work of Foucault and followers on the nature of power.

Organisms are not billiard balls, propelled by simple and measurable external forces to predictable new positions on life's pool table. Sufficiently complex systems have greater richness. Organisms have a history that constrains their future in myriad, subtle ways.

With the subsequent strong support from cybernetics, the concepts of systems thinking and systems theory became integral parts of the established scientific language, and led to numerous new methodologies and applications -- systems engineering, systems analysis, systems dynamics, and so on.
