Author deals with Deleuze's conception of conceptual person which in What is philosophy?, written in co-authorship with Félix Guattari, forms together with concept and plan of immanence philosophical trinity. The strategical role of conceptual person is that it asists to the concept on one side and to the plan of immanence on the other. At the same time it represents the medium through which philosopher can expres himself. Conceptual person, however, is not a tool or representative of the prhilosopher, but mad, schizophrene cogito, which “thinks inside the philosopher”. Conceptual person is Deleuze's variant of Rimbaud's thesis “Je est un autre”, which is posible only on the background of Kant's insight that madneš of the subject corresponds to the time which is out of joint. For that reason Deleuze claims that philosophy is dice throw, which does not mean only that philosophy is permanently in crisis, but that task of philosophy is to produce something new, something which is not thinkable form the present, which on the contrary resist to it, throws it out of joint.V prispevku avtorja zanima Deleuzovo pojmovanje konceptualne osebe, ki v Qu'est-ce que la philosophie?, ki jo je Deleuze napisal skupaj s Félixem Guattarijem, poleg koncepta in plana imanence tvori filozofsko trojstvo. Strateška vloga konceptualne osebe je najprej v tem, da koncept in plan imanence brez nje ne moreta, hkrati pa konceptualna oseba predstavlja medij, skozi katerega se filozof izraža. Toda konceptualna oseba ni orodje ali reprezentant filozofa, pač pa predstavlja nori, shizofreni cogito, ki “misli v samem filozofu”. Konceptualna oseba je Deleuzova različica Rimbaudove teze “Je est un autre”, ki je mogoča le na ozadju Kantovega uvida, da norosti subjekta ustreza čas, ki je out of joint. Zato Deleuze tudi pravi, da je filozofija met kock, kar ne pomeni le tega, da se filozofija nahaja v permanentni krizi, pač pa tudi, da je naloga filozofije proizvesti novo, ki ni mišljivo izhajajoč iz sedanjega, pač pa se sedanjemu upira, ga vrže iz tira
