This paper explores the relationship between conceptual thinking, spatiality, and temporality within the context of ancient Greek philosophy and geometry. The author argues that the Greek attempt to emancipate thought from the lived world resulted in models that distanced themselves not only from time but also from the inherent spatiality of our reality. While geometry appears to construct a space devoid of time, it retains traces of spatiotemporality and subject activity that resist complete objectification. This impossibility of total objectification is illustrated through the problem of identity and mirror symmetry in geometric figures, specifically triangles. The author demonstrates that the identity of mirror-image counterparts cannot be established within a two-dimensional plane without invoking an external action—lifting and flipping the object—which implies movement and an event. Consequently, the text challenges purely spatial interpretations of identity and emphasizes that temporality remains an inextricable part of geometric constructions and conceptual models.
