What is understood when “man” is understood? This question proves troublesome for Peter Abelard’s nominalist account of universal understandings which, to be sound, must attend to things as they really are. If there are no universal things, how can universal understandings be sound? His answer, in the Treatise on Understandings, is that such understandings, far from being about nothing, are about natures. However, it is hard to see how this solves the problem, given how he states earlier in the treatise that natures are identical to individuals. In this paper, I present a reading of what he means by “nature” that allows us to make sense of his proposed solution to the problem. In addition, I contend that, for his solution to work, the relevant relation between the mind and the world is to be understood as attention, instead of his previous view based on similitude.

This book promotes the research of present-day women working in ancient and medieval philosophy, with more than 60 women having contributed in some way to the volume in a fruitful collaboration. It contains 22 papers organized into ten distinct parts spanning the sixth century BCE to the fifteenth century CE. Each part has the same structure: it features, first, a paper which sets up the discussion, and then, one or two responses that open new perspectives and engage in further reflections. Our authors’ contributions address pivotal moments and players in the history of philosophy: women philosophers in antiquity, Cleobulina of Rhodes, Plato, Lucretius, Bardaisan of Edessa, Alexander of Aphrodisias, Plotinus, Porphyry, Peter Abelard, Robert Kilwardby, William Ockham, John Buridan, and Isotta Nogarola. The result is a thought-provoking collection of papers that will be of interest to historians of philosophy from all horizons. Far from being an isolated effort, this book is a contribution to the ever-growing number of initiatives which endeavour to showcase the work of women in philosophy.

This thesis focuses on Abelard’s solution to the problem of understanding universals as presented in the Tractatus de Intellectibus. He examines this issue by asking what is understood when we consider the term ‘man’, a problem I call the ‘homo intelligitur [man is understood]’ problem. This is an important question, since earlier in the Treatise, Abelard states that understandings paying attention [attendens] to things otherwise than they are are empty, and thus, cannot be true. The challenge is therefore to explain how understandings about universals, such as genera and species, can be sound, given that Abelard is a nominalist and, as such, does not believe in the existence of universal entities. His own answer to the problem is that such understandings attend to natures. However, since natures are, on his view, nothing more than the individuals they belong to, it is unclear how his solution is intended to work. I propose two ways to understand Abelard’s solution to the ‘homo intelligitur’ problem, identifying their respective merits and drawbacks. The first one is to treat ‘nature’ as meaning ‘status’. I explore this solution in Chapters 2 and 3, and conclude that while it has the advantage of establishing links between De Intellectibus and previous logical works by Abelard, it has some significant drawbacks, most notably that it is unclear how we can have epistemic access to status given that status are not things, which renders unclear how the criteria for the soundness of understandings can be met. The second one involves treating natures as referring to behaviors typical of members of a given genus or species. These behaviors come from the particular essential forms possessed by individuals, i.e. their differentiae understood as analogous to nuclear tropes in Peter Simons’ trope theory. I conclude that this solution is more intuitive than the first one and has the advantage of not depending on a specific interpretation of the evolution of Abelard’s thought. However, it is unclear how to treat behaviors and regularities in his ontology.
