In European philosophical psychology, the work of Jacques Lacan has exerted a great deal of influence but it has received little attention from analytic philosophers. He is famous for the view that the unconscious is a repository of influences arising from language and the meanings it captures, but the presentation of his ideas is sometimes perplexing and impenetrable and its conceptual links with analytic philosophers like Frege and Wittgenstein are not easily discerned. In fact, there are a number of such links and they are worth pursuing for those interested in language, mind, and the unconscious. If we explore Lacan's claim about the link between signification and the tuchè (the encounter with the real) we find that the mental content of the subject is essentially tied to the external world both causally and linguistically. The means of tying the two together arise in the context of human interactions and therefore are charged with personal and emotive content as well as the semantic content with which we are normally concerned in philosophy of language. When we pursue the implications of his view it becomes plausible both that the unconscious is structured like a language and that language borrows much of its meaning and significance to a subject from the interpersonal medium through which it has been inscribed on that subject. His approach is therefore illuminating both for linguistics (especially psycholinguistics) and for the psychology of the unconscious.

Libet's experiments, supported by a strict one-to-one identity thesis between brain events and mental events, have prompted the conclusion that physical events precede the mental events to which they correspond. We examine this claim and conclude that it is suspect for several reasons. First, there is a dual assumption that an intention is the kind of thing that causes an action and that can be accurately introspected. Second, there is a real problem with the method of timing the mental events concerned given that Libet himself has found the reports of subjects to be unreliable in this regard. Third, there is a suspect assumption that there are such things as timable and locatable mental and brain events accompanying and causing human behaviour. For all these reasons we reject the claim that physical events are prior to and explain mental events
