The third category of the psyche in Lacanian psychoanalysis is the real (réel), which is neither imaginary nor symbolic in conscious or unconscious thought, and which is inaccessible to psychoanalysis itself. The real is not reality in either a conceptual or phenomenological sense, which is the symbolic and the imaginary: it is only proposed as an algebraic concept, as it cannot be conceived.
