Welcome to POTESTAS ESSENDI. If you want to know more about philosophical intricacies concerning nature and its fading hylomorphic roots as they were envisioned by medieval thinkers, I guess this is the right place. You can find here materials of different nature and scope, following the development of my research interests over time. Much of it is related to the tension between ontology and natural philosophy in the Middle Ages and, specifically, the concepts of matter, prime matter, and materiality.

However, POTESTAS ESSENDI offers more than just specialised stuff for people with strange interests. One of the main questions I have been asking myself during the past few years is how medieval philosophy can be “communicated” in the sense of “shared” and made “common” as per the original sense of the Latin verb“communicare”. Hence, POTESTAS ESSENDI also hosts some projects directed to a wider audience of people who might be interested in knowing more about medieval stuff.

I’m Nicola Polloni, the editor of POTESTAS ESSENDI. Hence, you will find a lot of information about me in this website. I work on medieval philosophy, more specifically on the ontological constitution (why a thing is what it is) of the natural world (from squirrels to rocks, and their constituents). Even more specifically, I work on hylomorphism, a theory claiming that all bodies are made of matter and form and which was the main framework of premodern natural philosophy and science.

I come from Siena, in Tuscany. But I had to travel a lot, studying and working in Italy, Spain, the US, the UK, Germany, and now Belgium, where I am currently working at KU Leuven.
