Abstract
The attempt to understand and develop Plato's philosophical views has a long history, starting with Aristotle and Plato's institutional successors in the academy towards the end of the fourth century bc. This article traces the history and development of the idea of Platonism. The development of a specifically Platonic philosophy took place mainly within the academy. As a result, the idea that Plato's dialogues already presented a well defined, comprehensive, and essentially correct philosophical system seems not to have arisen until the first century bc. And it was probably not until toward the beginning of the second century ad that a disparate set of philosophers who identified themselves as “Platonists” conceived the project of advocating and defending a specifically Platonic philosophy of this kind by systematically interpreting and explaining Plato's texts.
