Cosmology and Argument in Ancient Philosophy

21–22 August 2025 Faculty of Philology

The aim of this conference is to gather a select group of scholars working on ancient cosmology, logic, epistemology, and metaphysics to explore the interaction between ancient cosmologies and arguments from the Presocratics to Late Antiquity, how different modes of argumentation interact in a single author or a group of authors, and whether there was, if any, an evolution of these themes in the history of ancient Greek philosophy. The conference will take place at K. Donelaitis Room, Faculty of Philology, Universiteto st. 5.

Abstract

Cosmological Arguments in the School of Hypatia

This paper is dedicated to examining the evidence of the biological model of emanation in the sources originating from Hypatia’s school. In the first part of the talk, I explain the methodology I use to collect extracts (primarily from the works of Hypatia’s pupils). In the second part, I present the reconstruction of the account of cosmic emanation grounded in the biological model of growth. In the third part, I discuss possible sources of inspiration for this model in Plato and later sources, as well as polemical motivations for developing it.
