Plato’s Inner-academic Teachings in the Light of New Research
International conference in honour and commemoration of Prof. Dr. Dr. h.c. Jens Halfwassen (1958–2020)
|
At the core of Plato’s inner-academic teachings lies his metaphysic. The questions, however, how this metaphysic is to be understood in detail and how it relates to the Old Academy have been controversially disputed throughout the 20th and 21st century. Recently, there have been numerous seminal new publications concerned with these questions. The conference aims to concentrate and to openly discuss the current state of research, thereby letting different positions enter in dialogue with one another. The programme places Plato’s inner-academic teachings in a broad systematic and historic context. In particular, the relation of the Theory of Principles to ethics, political philosophy and mathematics are discussed, besides further selected philosophemes. Furthermore, the tradition of the Old Academy as well as crucial questions concerning sources will be addressed. Finally, the conference aims to identify future fields and questions of research regarding Plato’s inner-academic teachings. The conference is generously funded by the Fritz Thyssen Stiftung and is supported by the Philosophy Department of Heidelberg University. Time: 01–03 December 2022 Registration. Since seats at the venue are limited, registration for in person-participation is mandatory. In order to do so, please send a message to christoph.poetsch@uni-heidelberg.de. Please indicate, with respect to the limitations of seats, on which days you plan to participate in person. The talks will be streamed online.
