ABSTRACTDeath as an inevitable reality is a subject of study in various philosophical schools. This concept can be reviewed within three realms: semantics, ontology, and epistemology. The objective of this article is to examine death within the ontological realm in the thoughts of Mullā Sadrā and Schopenhauer, and it attempts to answer the question whether philosophical discussions on the concept of death in Sadrā’s transcendental wisdom, despite differences in principles, methods, and objectives, are comparable to Schopenhauer’s intellectual framework. Using a (...) descriptive-analytical approach, the present study first investigates the issue of death in the thought of both philosophers and then focuses on their comparative analysis. The findings of this study show that both philosophers believe in the dichotomy in the world, immortality of human nature after death, existence of suffering in the world, asceticism, austerity, love, and affection to all human beings. However, each of them analyzes and explains the issue of death within his own intellectual framework. (shrink)
