At its most compelling, the unthought known stands for those early schemata for interpreting the object world that preconsciously determine our subsequent life expectations.
[1] In this sense, the unthought known refers to preverbal, unschematised early experience/trauma that may determine one's behaviour unconsciously, barred to conscious thought.
[2] It has been suggested that behind Bollas's concept lay a comment reported by Freud from a patient to the effect that he had always known something but he had never thought of it.
Persistent moods can be considered to preserve elementary but preschematized states of mind into later life;[5] the complex early interplay of self and (primary) object may also be preserved in the unthought known;[6] early aesthetic experience – pre-verbal – can again form part of the unthought known.
[9] In therapy, the unthought known can become the subtext of the therapeutic interchange – the therapist's role then becoming that of picking up and containing (through projective identification) what the patients themselves cannot yet think about.
