Book excerpt: Greenberg creates a meeting ground for two strains of inquiry. One has to do with Freud's early neurological writings and his career as a research scientist; the other with the origins of psychoanalysis in the late nineteenth-century intellectual culture, particularly in theories of language. Aphasia studies encompass inquiry into language, brain, and consciousness, and, ultimately, the entire question of mind-body relations. The study of language disorders that result from brain damage shows the thirty-five-year-old Freud as a bold researcher who encountered in the sources he used some of the important ideas that would ultimately evolve into psychoanalysis.
