Miller's Living Systems Theory
James Grier Miller in 1978 wrote a 1,102-page volume to present his living systems theory. He constructed a general theory of living systems by focusing on concrete systems—nonrandom accumulations of matter–energy in physical space–time organized into interacting, interrelated subsystems or components. Slightly revising the original model a dozen years later, he distinguished eight "nested" hierarchical levels in such complex structures. Each level is "nested" in the sense that each higher level contains the next lower level in a nested fashion.
His central thesis is that the systems in existence at all eight levels are open systems composed of twenty critical subsystems that process inputs, throughputs, and outputs of various forms of matter–energy and information. Two of these subsystems—reproducer and boundary—process both matter–energy and information. Eight of them process only matter–energy. The other ten process information only.
All nature is a continuum. The endless complexity of life is organized into patterns which repeat themselves—theme and variations—at each level of system. These similarities and differences are proper concerns for science. From the ceaseless streaming of protoplasm to the many-vectored activities of supranational systems, there are continuous flows through living systems as they maintain their highly organized steady states.
Seppänen (1998) says that Miller applied general systems theory on a broad scale to describe all aspects of living systems.

Famous quotes containing the words miller, living, systems and/or theory:
“When I think of some of the Persians, the Hindus, the Arabs I knew, when I think of the character they revealed, their grace, their tenderness, their intelligence, their holiness, I spit on the white conquerors of the world, the degenerate British, the pigheaded Germans, the smug self-satisfied French.”
—Henry Miller (1891–1980)
“Thus change the forms of being. Thus arise
Races of living things, glorious in strength,
And perish, as the quickening breath of God
Fills them, or is withdrawn.”
—William Cullen Bryant (1794–1878)
“Before anything else, we need a new age of Enlightenment. Our present political systems must relinquish their claims on truth, justice and freedom and have to replace them with the search for truth, justice, freedom and reason.”
—Friedrich Dürrenmatt (1921–1990)
“A theory of the middle class: that it is not to be determined by its financial situation but rather by its relation to government. That is, one could shade down from an actual ruling or governing class to a class hopelessly out of relation to government, thinking of gov’t as beyond its control, of itself as wholly controlled by gov’t. Somewhere in between and in gradations is the group that has the sense that gov’t exists for it, and shapes its consciousness accordingly.”
—Lionel Trilling (1905–1975)
