In philosophy, A. Shirakatsi’s perception of time had its own characteristics, and his consideration was not always detailed or systematized, compared to the later philosophical traditions. A. Shirakatsi’s concepts of time can be seen in his reflections on infinity and finitude, in polemics with “evil pagan” philosophers and Chaldean astrologers. The categories of time in the philosophy of the Armenian philosopher are found in the context of metaphysics, an important component of which was the understanding of time in Aristotle’s philosophy.
