The paper investigates the problems of convergence of philosophy and theatre, the amount of actors' contribution to creating or performing oral philosophical text, to analyze the professional philosopher's (or a teacher of philosophy) methods that are used to "vividly reproduce" the philosophical views in the minds of the listening audience, which brings together the art of philosopher's speech and performing arts. The analysis of K. Stanislayski, M. Chekhov, Jerzy Grotowski's works on the art of acting, along with the works on the phenomenon of theatre (namely, of A. Badiou), and a range of classical philosophical works, that are analyzed in terms of their performing potential, could contribute to highlighting the central issue: what really makes oral philosophical text expressive. A possible answer is the image of the thought that has its specific space or stage for performance, set by philosopher himself by "drama" means. The unity of philosophy and theatre has a bright future ahead. It is already obvious that the process of thinking alongside acting and happening will become a central point of a public thinker's activity.
