Jacques Lacan, anyone?

I’m wondering whether I should delve into Lacan. I am only vaguely aware of him and have never read any of his published essays or lectures. From what I’ve gleaned, I may end up down some rabbit hole. His interest in the function of language interests me, but his analogy of that to psychoanalysis is disconcerting.

The analogy is fine, but I have a problem with the entire field of psychoanalysis as I view it as pseudoscience. As with Freud and Jung, the speculation around the unconscious and their metaphors are fine storytelling, but that’s about it.

My interest is in his structural approach to language and the notion I share concerning the lack of specificity in language, but it seems to me that my time would be better spent reading Derrida.

Lacan is categorised as both a structuralist and a post-structuralist, which might be correct given the period in which he lived, but I am still trying to figure out how he might be considered to be a post-structuralist, as he seems to be concerned with a sense of order, which is somewhat antithetical to this worldview.
