An exceptional collection of essays and letters by Althusser that greatly clarify his understanding of psychoanalysis, as well as how he viewed and inherited methods/concepts from Lacan. Althusser's own positions on certain matters, it must be said, do not parrot Lacan; for instance, near the end of his second letter to his psychoanalyst, René Diatkine, he takes Lacan's dictum from the Rome Discourse and "The Instance of the Letter" ('the unconscious is structured like a language') and says “one would have to… say that the unconscious is structured like that “language [langage]” (which is not a langue) which is the ideological and that this resemblance of structures must be understood in a far more elaborate sense than in the case of the “resemblance” between the structure of the unconscious and that of language. It would be a matter of semblance would no longer be merely formal but would call into play affinities of matter (the imaginary) and of organizational structure (thus at a degree further toward the concrete). To be sure, it is not a matter of reinstating a new genesis-filiation; the structure of the unconscious is a structure other than that of the ideological” (76-77). Very helpful for understanding the rest of Althusser's oeuvre, especially his work on ideology! Though, of course, Althusser may be at times wanting (he is clearly NOT a psychoanalyst), this is nevertheless a useful collection of historical documents that help to piece together the intellectual history around Althusser, specifically his engagements with psychoanalysis.
