The subject matter of section 1 is often reduced to a single chapter or, more typically, a paragraph in recent reviews of OCD. Here the reader is provided eight papers regarding classical psychoanalytic theory and OCD—including three by Sigmund Freud and one by Anna Freud, intermingled with works by Ernest Jones, Karl Abraham, Peter Sifneos, and Leonard Salzman. I expect that different readers will respond very differently to this section. Stein wonders (rhetorically) whether "such papers.are mere historical curiosities." Empiricists may be frustrated by the rambling presentation of theories accompanied by limited structure for hypothesis testing. Indeed, although there is some mention of it, the lack of data to support the efficacy of psychoanalytic approaches in the treatment of OCD should have been further underscored. This section illustrates the early struggle with terminology that actually remains unresolved today. In this context, some greater emphasis regarding the distinction between OCD and its namesake among the personality disorders, as well as a historical account of evolving terminology across the versions of DSM, would have been most instructive. Nonetheless, I thoroughly enjoyed the case material—hammering home the heterogeneity of OCD juxtaposed with its ageless visage, which has been almost invariant across centuries. There is also much to recommend these works aside from their pertinence to OCD; for instance, Jones's discussion regarding the psychology of hate is wonderful.
