This book addresses death and immortality by paralleling Plato's philosophy of 'becoming like God' through exercising one's intellect and virtues, with the Greek archaic and heroic way of gaining immortal glory through remarkable deeds. In doing so, this study focuses on the explicit and implicit references to earthly immortality and heroism in Plato's dialogues, arguing for a distinction between the Time-bound ontology of the glory-seeking individual and the Being-centered ontology of the philosopher. Such an underlining of the ontological discrepancy between the ways of the hero and those of the philosopher makes this book a novel academic contribution. The dual focus discloses the clash of ontologies yet also reveals an implicit existential turmoil in Ancient Greek culture as to the anxieties surrounding one's potential immortality. This title appeals to students and researchers working in Ancient philosophy and existentialism.
