The pleasure of thought during the session is an intellectual feeling, that can take several forms at different moments during the analyst's thought process. The following should be distinguished: the disruption introduced by interpretative interference, which by underlining an unconscious element, upsets the conscious logical flow of the analysand's speech; finding the key-word or the overdetermined image which springs to the mind in the same way as a poet finds a rhyme; the resurgence of a memory, once evoked and subsequently forgotten again by the analysand, which imposes itself with quasi hallucinatory sharpness in the analyst's representative space; the experience of co-thought, either on one particular occasion related to a specific representation, or as a complement, accompanying the analysand's associative process.
