Essays on key moments in the intellectual history of the West. This book forms a major contribution to the discussion on fate, providence and moral responsibility in Antiquity, the Middle Ages and Early Modern times. Through 37 original papers, renowned scholars from many different countries, as well as a number of young and promising researchers, write the history of the philosophical problems of freedom and determinism since its origins in pre-socratic philosophy up to the seventeenth century. The main focus points are classic Antiquity (Plato and Aristotle), the Neoplatonic synthesis of late Antiquity (Plotinus, Proclus, Simplicius), and thirteenth-century scholasticism (Thomas Aquinas, Henry of Ghent). They do not only represent key moments in the intellectual history of the West, but are also the central figures and periods to which Carlos Steel, the dedicatary of this volume, has devoted his philosophical career.
