We will survey ancient theories of causation, and the associated relationships of contact, mixture, and interpenetration. Our aim is also to understand how these theories guided the development of physics, metaphysics, and ethics more broadly. We will focus in particular on the works of Plato, Aristotle, Chrysippus and Epicurus. Towards the end of the course, we will examine how the ancient conversation about causation and contact set the stage for the development of early modern physics and philosophy, with particular attention to the development of Hume’s famous critique of causation as an empty concept.

An examination of ancient Greek philosophical texts that are foundational for Western philosophy, especially the work of Plato and Aristotle. Topics will include: the nature and possibility of knowledge and its role in human life; the nature of the soul; virtue; happiness and the human good.

Thomas Aquinas is sometimes labeled an “intellectualist,” because of the priority that he assigns to intellect or reason in human life. Nevertheless he treats love as a fundamental principle, not only of human life but of absolutely all life and even all reality, and he thought and wrote extensively about it.  In this course we will read and discuss sizeable passages, from several of his works, concerning the nature of love in general, its various kinds, its causes and effects, how it exists in different subjects — human, angelic, divine, and even non-rational — and what it has to do with morality, virtue, and happiness. As regards the history of the topic, the we shall especially want to consider how Aquinas’s thought on love relates to that of Aristotle and to the Platonic tradition. (A)

Any language contains terms that apply truly, and in the same sense, to indefinitely many things; for instance, species- or genus-terms, such as hippopotamus or animal. How things admit of such “universal” terms has engaged philosophers ever since Plato, who proposed participation in the forms. In the third century, the Neoplatonist Porphyry wrote an introduction to Aristotle’s Categories, in which he raised, but did not even try to answer, three metaphysical questions: whether genera and species are real or only posited in thoughts; whether, if real, they are bodies or incorporeal; and whether, if real, they are separate entities or belong to sensible things. At the beginning of the medieval period, another Neoplatonic thinker, Boethius, took up Porphyry’s questions. He offered a strict definition of universals, explained the difficulty of the questions, and proposed (without fully subscribing to) what he took to be Aristotle’s way of answering them. Boethius’s treatment oriented the approach to universals by philosophers up through the 12th century. The tools at their disposal, however, were mostly those provided by ancient logical works; and perhaps for this reason, the discussion reached a kind of impasse. But then there appeared translations of numerous hitherto unknown writings of Aristotle and Arab thinkers. Aristotle’s hylomorphism and his doctrine of (what came to be called) abstraction, together with the notion of “common nature” proposed by Avicenna (also a Neoplatonist), seemed to show a way out of the impasse. But they also raised new questions of their own—partly because of their sheer difficulty, and partly because of theological pressures, in the late 1200s, against the standard Aristotelian account of individuation by “matter.” The topic of universals thus tracks various other prominent themes in medieval metaphysics. We will look at background passages in Aristotle and Porphyry, and study texts of some of the most important authors, including Boethius, Abelard, Avicenna, Aquinas, Scotus, and Ockham. (B) (III)

What is the relationship between physical processes in the brain and body and the processes of thought and consciousness that constitute our mental life? Philosophers and others have puzzled over this question for millenia. Many have concluded it to be intractable. In recent decades, the field of cognitive science--encompassing philosophy, psychology, neuroscience, computer science, linguistics and other disciplines--has proposed a new form of answer.  The driving idea is that the interaction of the mental and the physical may be understood via a third level of analysis: that of the computational. This course offers a critical introduction to the elements of this approach, and surveys some of the alternatives models and theories that fall within it. Readings are drawn from a range of historical and contemporary sources in philosophy, psychology, linguistics and computer science.

In this seminar we engage in an in-depth examination of a focused philosophical topic—in a manner akin to that of a graduate seminar. Readings are challenging, but there is no presumption of prior expertise in the course topic.

We will be interested in the special and problematic notion of an attitude toward the world as a whole, and in some questions that arise in contexts where people face what they experience as the end of their world or its vulnerability to destruction.  Readings will include texts from Freud, Heidegger, and Wittgenstein, as well as more contemporary readings from Cora Diamond, Jonathan Lear, Brian O’Shaughnessy, and others.

This will be a careful reading of what is widely regarded as the greatest work of modern philosophy, Immanuel Kant's Critique of Pure Reason. Our principal aims will be to understand the problems Kant seeks to address and the significance of his famous doctrine of "transcendental idealism". Topics will include: the role of mind in the constitution of experience; the nature of space and time; the relation between self-knowledge and knowledge of objects; how causal claims can be justified by experience; whether free will is possible; the relation between appearance and reality; the possibility of metaphysics.
