Since the 1960s everyone has been familiar with the idea of ecology. Nature, before humanity, as the ecologists argue, constituted a balanced and indeed a self-balancing system. James Lovelock in his various books with Gaia in the title argues that nature before humanity constituted a “homeostatic” system that was not only self-regulating but capable of responding to gross unbalancing influences by vigorous redistributions of the disturbance so as to restore the norm of homeostasis. These observations apply largely to nature considered as the terrestrial biosphere, but Lovelock’s theory extends by implication beyond the restricted earthly system – all the way out to the asteroid belt.
According to the theory of natural ecology, every element of nature is linked recursively, by plural feed-back loops, to every other element; the elements work together as a whole to maintain a settled norm overall. Environmentalism, a political development of the idea of natural ecology, claims, however, that the human element of the system is an emergent anomaly whose presence upsets the ability of nature to maintain homeostasis. Whether the environmentalist claim concerning humanity is true or false, the general notion that a self-regulating system might suffer disruption from influences that are somehow external to it is highly plausible.
The term ecology is an ingenious coinage, probably needed at the time it entered into usage. The Greek word oikos means “house” or “household”; the Greek word logos – as its derivative logic suggests – is not only the orderly discussion of a phenomenon but also the internally self-regulating, form-endowing law that renders a phenomenon thus-and-such rather than something else and that keeps the phenomenon in this character steadily so that it remains recognizable and amenable to cognition. The term ecology thus elegantly, although perhaps not intentionally, reflects the notion of the universe as an orderly artifact, corresponding to a rational plan and having a discernible goal – that of steady self-maintenance.
