This book investigates Aristotelian psychology through his works and commentaries on them, including De Sensu, De Memoria and De Somno et Vigilia. Authors present original research papers inviting readers to consider the provenance of Aristotelian ideas and interpretations of them, on topics ranging from reality to dreams and spirituality. Aristotle’s doctrine of the ‘common sense’, his notion of transparency and the generation of colours are amongst the themes explored.
