“Philosophy in ‘Hamlet’” is a revised, updated and enlarged version of the magister’s thesis which was successfully defended at the Faculty of Dramatic Arts of Belgrade University in 2012, as the first thesis on “Hamlet”. On the basis of the study of “Hamlet” by Lev S. Vygotsky, the book “Philosophy in ‘Hamlet’” points out the philosophical problems set in Shakespeare’s enigmatic tragedy: the problem of being, the problem of the nature of reality, or another reality and another world, the problem of the transcendent, as well as the problem of time which is associated with a four-dimensional perception of reality, feelings of absurdity and meaning, then the problem of the supernatural, idem est the metaphysical, and the philosophy expressed in the tragedy of “Hamlet”.
