"This book, by Anthony Long, explores the concepts of selfhood and rationality within ancient Greek philosophy, spanning seven centuries from Heraclitus to Plotinus. It examines how Greek philosophers connected the rational self to ideas of divinity and *eudaimonia* – a life of flourishing or likeness to the divine. The essays delve into the contributions of key figures like Socrates, Plato, Aristotle, and the Stoics, considering their views on the soul's rationality and identity. While rooted in ancient thought, the book also bridges these historical perspectives with modern discussions about the self and its relationship to others and the world."
