Written by a group of leading scholars, this unique collection of essays investigates the views of both pagan and Christian philosophers on causation and the creation of the cosmos. Structured in two parts, the volume first looks at divine agency and how late antique thinkers, including the Stoics, Plotinus, Porphyry, Simplicius, Philoponus and Gregory of Nyssa, tackled questions such as: is the cosmos eternal? Did it come from nothing or from something pre-existing? How was it caused to come into existence? Is it material or immaterial? The second part looks at questions concerning human agency and responsibility, including the problem of evil and the nature of will, considering thinkers such as Plotinus, Porphyry, Proclus and Augustine. Highlighting some of the most important and interesting aspects of these philosophical debates, the volume will be of great interest to upper-level students and scholars of philosophy, classics, theology and ancient history.
