Scurvy And The Ontology Of Natural Kinds, P.D. Magnus Jan 2023

Scurvy And The Ontology Of Natural Kinds, P.D. Magnus

Philosophy Faculty Scholarship

Some philosophers understand natural kinds to be the categories which are constraints on enquiry. In order to elaborate the metaphysics appropriate to such an account, I consider the complicated history of scurvy, citrus, and vitamin C. It may be tempting to understand these categories in a shallow way (as mere property clusters) or in a deep way (as fundamental properties). Neither approach is adequate, and the case instead calls for middle-range ontology: starting from categories which we identify in the world and elaborating their structure, but not pretending to jump ahead to a complete story about fundamental being.


How To Be A Realist About Natural Kinds, P.D. Magnus Dec 2018

How To Be A Realist About Natural Kinds, P.D. Magnus

Philosophy Faculty Scholarship

Although some authors hold that natural kinds are necessarily relative to disciplinary domains, many authors presume that natural kinds must be absolute, categorical features of the reality— often assuming that without even mentioning the alternative. Recognizing both possibilities, one may ask whether the difference especially matters. I argue that it does. Looking at recent arguments about natural kind realism, I argue that we can best make sense of the realism question by thinking of natural kindness as a relation that holds between a category and a domain.


Cautious Realism And Middle Range Ontology, P.D. Magnus Nov 2018

Cautious Realism And Middle Range Ontology, P.D. Magnus

Philosophy Faculty Scholarship

Anjan Chakravartty's book Scientific Ontology is centrally about how metaphysics is embrangled with epistemology. I begin by discussing the broader literature in science and values, where arguments akin to Chakravartty's have been much-discussed. Then I talk about my own preferred approach, middle range ontology, which does not fit neatly into any of the three stances Chakravartty discusses. Finally, I use these considerations to pose a dilemma.

Introduction, John Dillon, David D. Butorac, Danielle A. Layne

Philosophy Faculty Scholarship

The introduction to Proclus and His Legacy, a volume which investigates Proclus' own thought and his wide-ranging influence within late Neoplatonic, Alexandrine and Byzantinian philosophy and theology. It further explores how Procline metaphysics and doctrines of causality influence and transition into Arabic and Islamic thought, up until Richard Hooker in England, Spinoza in Holland and Pico in Italy. John Dillon provides a helpful overview of Proclus' thought, Harold Tarrant discusses Proclus' influence within Alexandrian philosophy and Tzvi Langermann presents ground breaking work on the Jewish reception of Proclus, focusing on the work of Joseph Solomon Delmedigo (1591-1655), while Stephen …


Art Concept Pluralism, P.D. Magnus, Christy Mag Uidhir Jan 2011

Art Concept Pluralism, P.D. Magnus, Christy Mag Uidhir

Philosophy Faculty Scholarship

There is a long tradition of trying to analyze art either by providing a definition (essentialism) or by tracing its contours as an indefinable, open concept (antiessentialism). Both art essentialists and art anti-essentialists share an implicit assumption of art concept monism. We argue that this is a mistake. Species concept pluralism, a well-explored position in philosophy of biology, provides a model for art concept pluralism. We explore the conditions under which concept pluralism is appropriate, and we argue that they obtain for art. Art concept pluralism allows us to recognize that different art concepts are useful for different purposes, and …
