It is a commonplace to say that in antiquity philosophy was conceived as a way of life or an art of living but precisely what such claims amount to has remained unclear. If ancient philosophers did think that philosophy should transform an individual's way of life, then what conception of philosophy stands behind this claim? In The Art of Living John Sellars explores this question via a detailed account of ancient Stoic ideas about the nature and function of philosophy. He considers the Socratic background to Stoic thinking about philosophy, Sceptical objections raised by Sextus Empiricus, and offers readings of late Stoic texts by Epictetus and Marcus Aurelius. Sellars argues that the conception of philosophy as an 'art of living', inaugurated by Socrates and developed by the Stoics, has persisted since antiquity and remains a living alternative to modern attempts to assimilate philosophy to the natural sciences. It also enables us to rethink the relationship between an individual's philosophy and their biography.
A glimpse inside

Sellars argues that, for the Stoics, philosophy was fundamentally about transforming one’s way of living. Unlike modern views that often separate philosophy from everyday concerns, the Stoics saw it as a practical discipline aimed at achieving eudaimonia—flourishing or happiness. This approach treats philosophy as a set of exercises, habits, and commitments that shape character and conduct, not just abstract reasoning.
The book traces the Stoic conception of philosophy back to Socrates, who famously lived his philosophy in public and private life. Sellars emphasizes how Socratic questioning and the pursuit of self-knowledge laid the groundwork for later Stoic practices. This lineage is crucial: it shows that the Stoic art of living is part of a broader tradition that values philosophical inquiry as a means to personal transformation.
