What is a thing? Anything we can think about? But, if so, what about nothing, falsity, fictional and impossible beings? Are they also things or rather something else? In short, what kinds of entities are there at all?
The series On What There Was aims to reveal how, from the schools of the late ancient Greek world, there emerged in the three main philosophical traditions of the Western Middle Ages – the Arabic-Islamic, Hebrew-Jewish, and Latin-Christian – ontological discussions which contributed decisively to the formation of early modern Western thought.
