Ideology Is Monoculture
As Henry David Thoreau put it: "In wildness is the preservation of the world." Fundamentally this refers to biodiversity. A wilderness area is much more stable and resilient than lands cultivated by human effort. The movement away from natural diversity is described as the movement toward monoculture. Metaphorically speaking, ideology is a form of monoculture. It narrows the intellectual and ethical options available within individuals, and requires more external involvement to keep it functioning. The whole thing is propped up by various control mechanisms -- the social equivalent of pesticides -- all of which bear the mark of authoritarianism.
