research interests
seventeenth century philosophy: My main area of research over the past 25 years has been seventeenth century philosophy, particularly that of Leibniz. I have a book contract with Polity Press in England for a Leibniz for their Classic Thinkers series. I am also currently completing a (possibly 2-volume) work on Leibniz's natural philosophy and metaphysics based on his solution to the continuum problem: Ariadnean Threads . In it I offer new interpretations of Leibniz's theory of substance, his theory of the infinite and infinitesimals, and his theories of space, time, motion and continuity.
I have also been investigating the lively atomist tradition of the early seventeenth century and its connection with biology, theology, and the chymical tradition, particularly in the work of Daniel Sennert.
philosophy of physics: One of my main current interests is the close relationship between time and inertia, on which I have written two papers , "Time, Inertia and the Relativity Principle" (archived paper) in Minnesota, and "Time and Inertia" in Montreal. I have written a chapter for a book project for Springer with Steve Savitt of UBC and Dennis Dieks of Utrecht on The 'Now' in Physics, but although the book has now fallen through, the project may still result in publications. The Time and Universe (tau) Cluster, a collaborative venture with other physicists and philosophers in Canada and around the world, is on hold pending a successful bid for funding. I have recently written on virtual processes, showing the close relationship between them and the phenomenon of quantum tunnelling; I argue that neither can be interpreted in terms of particle transmission, since that would involve processes with imaginary mass travelling backwards in time.
history and philosophy of time: I am also doing substantial work on early modern philosophy of time. I gave a paper on Descartes's debt to Beeckman in his philosophy of time at a symposium in Chicago in mid-February 2010. This is part of a projected third book project treating the interconnection of views on time, force and activity in seventeenth century natural philosophy, Matters of Moment.
philosophy of the infinite: Fourth, arising out of my work on Leibniz, I have been defending an account of the actual infinite that is a rival to the Cantorian account, but which eschews infinite sets. On this topic I have written a dialogue between Leibniz and Cantor, and five related papers: one on the development of Leibniz's early thinking on infinitesimals (abstract); a second on Leibniz's Law of Continuity (abstract); a third in which I compare Leibniz's syncategorematic interpretation of infinitesimals with that of Smooth Infinitesimal Analysis (abstract), a fourth comparing Newton and Leibniz on infinitesimals (abstract, articles online), and a fifth about to be published in the Netherlands, in which (inter alia) I offer a largely sympathetic critique of Deleuze's interpretation of Leibniz's calculus with respect to the rise of structuralism. articles online
epistemology of science, thought experiments: Fifth, I am part of a cluster of scholars interested in thought experiments. I published an article on Galileo's thought experiment on falling bodies and Jim Brown's Platonist interpretation of it, incorporating a weird dream, a partial defence of Feyerabend's views, and my interest in Diderot's materialist philosophy. I also recently read a paper in a workshop in Halifax on one of the world's oldest TEs, Aristotle's Wheel, perhaps originating with Archytas of Tarentum. I also co-hosted a workshop on the (contested) expanding role of applied mathematics from the Renaissance to the Enlightenment, in Pisa in September 2010.

- Phil 3E03/CS3Y03. Winter Term 2011. 3rd year course.
This course offers a lively introduction to some of the main philosophical issues concerning language. We will motivate the discussion by looking at attempts in the early modern period to devise a perfect language, the later discovery of the Indo-European nucleus of many of the world's languages, the invention of artificial languages, including modern logic and computer languages, the Whorf-Sapir hypothesis, and Chomskian linguistics.

- Origins 3A03.
Winter Term 2011. 3rd year course: co-lecturers: Ralph Pudritz, Cliff Burgess.
The aim of this course is to survey some of the most important ideas, theories, and experiments that mark the development of our understanding the origin of the cosmos and the nature of spacetime that defines it. Our lectures follow a historical treatment of some of the most important breakthroughs. We also use an interdisciplinary approach by combining history of science, mathematics, astronomy and astrophysics, and physics (such as particle physics). There will be some technical material involving physics and astronomy problems.

762.
Winter Term 2010. Graduate Seminar in selected Topics in
Metaphysics
-
- In this course we examine various deep issues in the metaphysics of time relating to the flow of time: does time flow? what are the arguments for and against? does it flow continuously or in discrete time atoms? what is the status of the present or 'now'? is temporal becoming refuted by Zeno's paradoxes? is there no world-wide 'now' according to modern physics? if so, do we live in a static or 'block universe'? does the possibility of time travel preclude temporal becoming? in what sense can past, present and future be said to exist? These
issues will be examined both in their historical context
and with reference to contemporary science and
philosophy.
