Gersonides has at times been viewed as an essentially orthodox Aristotelian in his metaphysical views. This designation, however, has been challenged on a number of grounds. This paper examines the way in which Gersonides revises the traditional conception of hylomorphism by positing that matter can exist without form. Motivated by a desire to reconcile Aristotelian natural philosophy with the Ptolemaic astronomical model, formless matter is seen as a necessary entity to posit in order for his cosmological model to be coherent. By allowing for this exception case, Gersonides turns hylomorphism from a metaphysical principle to a general, though not universal, principle of physics that can must be revised if other observational and philosophical commitments are to be maintained, which speaks to a distinct attitude toward Aristotelian metaphysics than is otherwise assumed to be the case for Gersonides and his contemporaries.

John Scotus Eriugena devotes a substantial portion of his Periphyseon to a longstanding cosmological question of whether the cosmos is eternal or created at a moment in time. This paper explores his examination of the question in light of the broader history of cosmology, as he straddles both antiquity and the Middle Ages by trying to integrate a Platonic ontology within a particular Christian framework. As a result, Eriugena produces a highly original solution to the debate that has been hitherto neglected in the broader conversation on this question. Finally, the paper situates this within Eriugena’s broader philosophical system and its significance in relation to his methodological approach.

This chapter explores the relationship between two themes of this volume, pantheism and ecology, as it is present in Pliny the Elder’s Natural History. Specifically, it examines the influence of Stoicism on Pliny’s cosmology, as he adopts and challenges philosophical positions associated with the Stoa, particularly in his engagement with the view that the entire cosmos is a single living being which governs the variety of natural phenomena in both the heavens and the sublunar world. Additional themes, such as the role of natural teleology and providence are explored, as these provide the intellectual foundation for what I consider to be Pliny’s “environmental ethics.” I argue that Pliny, despite often expressing an anthropocentric outlook toward nature, holds that, in virtue of the divinity of the Earth, there are certain human duties toward maintaining natural order. These are justified both in terms of the benefits they provide for humans as a species, given that the Earth is a source of food and other material goods, but also in terms of harms and benefits for the Earth itself. Recognizing the difference between goods that exist for our sake and that which exists for the benefit of the non-human world is a crucial distinction according to Pliny and one that underlies many of his comments about the duties humanity has toward Nature.
