Skepticism, Causality and Skepticism about Causality studies the interrelated themes of causality and skepticism in contemporary, early modern and medieval philosophy. Thomas Aquinas's celebrated proofs of the existence of God (the Five Ways of the Summa Theologica) rely in part on an Aristotelian notion of synchronous causality, wherein the things that exist and persist require an accounting that ultimately terminates in the ongoing activity of a first mover, as the existence and persistence of an ecosystem is traceable to the sun. By contrast, in David Hume's early modern account, causality...

Medieval semantic theories develop out of Aristotle's "On Interpretation", in which he notes that "Spoken sounds are symbols of affections in the soul, and written marks symbols of spoken sounds" (tr. J. L. Ackrill, OUP 1984). The medieval commentary tradition elaborates on Aristotle's theory in light of various epistemological and metaphysical commitments, including those entailed by the doctrine of the transcendentals that emerges from the tradition in the writings of Philip the Chancellor (d. 1236). Transcendental attributes such as unity, truth and goodness (properties that figure into...

Metaphysical Themes, Medieval and Modern presents three sets of essays that engage the metaphysics of substance through a study of thought on this theme over the last eight centuries, shedding light on contemporary disputes as well as the history of thought leading into the modern era. Part I grows out of an author-meets-critics panel on Robert Pasnau's Metaphysical Themes: 1274-1671 (OUP, 2011). Pasnau's rich study delves into the four centuries wherein later medieval thought gives way to the modern period. Andrew Arlig reflects on Pasnau's discussion of holenmers, entities such as God and...

Moses, Maimonides, and John Duns Scotus are key figures as regards the thirteenth-century philosophical tradition that developed out of the Western Christian reception of the Neo-Platonized Aristotelianism of Islamic and Jewish thinkers. Whereas the writings of Maimonides count among the received works that inaugurate and shape this span, the variety of conceptual instruments developed by Scotus arguably signal its end, preparing the way for the emergence of diverse fourteenth-century philosophical worldviews. Maimonides on God and Duns Scotus on Logic and Metaphysics explores the eponymous...
