Low theory is more about how subaltern or subordinate groups form a conceptual language to understand their situation, and to either escape it or struggle within it. One of the great historical examples of low theory is Marxism, but there are many other examples. To the extent that any oppressed and marginalized group borrows concepts or forges concepts specific to their situation, and produces means of communicating for thinking for themselves, then I think one has an example of low theory. Obviously, high and low theory interact all the time. Low theory borrows from high theory; high theory sometimes recuperates and canonizes low theory – Spinoza and Marx and low theorists who became canonized, for example. Neither was a professor.
