讲座简介：Alexander of Aphrodisias (ca 200 CE) has provided us with an update of Aristotle’s philosophy to meet the requirements of the philosophical debate in the second century CE. In his De anima he describes the acquisition of universal concepts from sense perception as a long process that ends in the acquisition of a form that actualizes the potentiality of intellect. This story implies a number of interesting innovations in Aristotelian psychology that have influenced later philosophy.
