POSTESTAS ESSENDI
Premodern Philosophy across Matter, Nature, and Worlds
Potestas essendi is a website devoted to medieval philosophy, with a particular focus on metaphysics, natural philosophy, and the history of hylomorphism. Across its pages, readers will find research materials, texts, videos, teaching resources, and tools designed for different audiences, from specialists and students to more curious visitors. Much of this work centres on matter, prime matter, materiality, and the transmission of knowledge, but the site also opens onto wider philosophical and intellectual concerns.
Alongside these core research interests, the website brings together the main dimensions of my academic activity, including publications, teaching, guides for students and early-career researchers, public outreach, and initiatives connected with medieval philosophy in Messina. It offers an organised point of access to the different forms my work takes across research, teaching, collaboration, and communication, while also providing a clearer sense of how these activities relate to one another.
Since its creation in 2016, Potestas essendi has been edited by Nicola Polloni. More information about my research, teaching, and academic activities is available here.
