This text is a posthumous work by Assoc. Prof. Josef Vinař (1934–2015), a lecturer at the Theatre Academy of Performing Arts in Prague. Before his death Josef Vinař asked his colleague Jan Vedral to take care of his unfinished theoretical work and make it available. Acting upon this wish and the wish of Vinař’s heirs, Jan Vedral put together a team from some of Vinař’s students (current doctoral students), who compiled Vinař’s theoretical ideas about theatre. The present study is a summary of some of Josef Vinař’s findings and especially his phenomenological ideas about the art of acting. The author prepared it for the Slovak Theatre journal.
