How is it that Freud is not taught in psychology departments, Marx is not taught in economics, and Hegel is hardly taught in philosophy? Instead these masters of Western thought are taught in fields far from their own. Nowadays Freud is found in literature departments, Marx in film studies, and Hegel in German. But have they migrated, or have they been expelled? Perhaps the home fields of Freud, Marx, and Hegel have turned arid. Perhaps those disciplines have come to prize a scientistic ethos that drives away unruly thinkers. Or maybe they simply progress by sloughing off the past.
A completely unscientific survey of three randomly chosen universities confirms the exodus. A search through the philosophy-course descriptions at the University of Kansas yields a single 19th-century-survey lecture that mentions Hegel. Marx receives a passing citation in an economics class on income inequality. Freud scores zero in psychology. At the University of Arizona, Hegel again pops up in a survey course on 19th-century philosophy; Marx is shut out of economics; and, as usual, Freud has disappeared. And at the University of Wisconsin at Madison, Hegel does not appear in philosophy courses, Marx does not turn up in economics, and Freud is bypassed in psychology.
The divorce between informed opinion and academic wisdom could not be more pointed. If educated individuals were asked to name leading historical thinkers in psychology, philosophy, and economics, surely Freud, Hegel, and Marx would figure high on the list. Yet they have vanished from their home disciplines. How can this be?
