I’m a philosopher based in Toronto, researching in early modern natural philosophy and mathematics, the theory of time, and the infinite. See research interests for details. See also latest news.

It is now 50 years since I began teaching (in Nairobi, in 1969), so I decided it was time to concentrate on research and writing. I retired from teaching in July 2018, and am Professor Emeritus at McMaster University (Hamilton, Ontario). 

My new book on Leibniz, Monads, Composition, and Force: Ariadnean Threads through Leibniz's Labyrinth, (xv + 329 pages, Oxford University Press) came out at the end of 2018. In it I offer new insights into Leibniz's theory of substance based on his solution to the labyrinth of the continuum, presenting it as a highly original account of the composition of bodies and motions that is neither phenomenalist nor materialist.

A second new book, The Reality of Time Flowlocal becoming in modern physics (vii + 304 pages in ms.), has also just been accepted for pubication  by Springer for their Frontiers Collection. In it I defend the reality of (local) becoming in modern physics against the multifarious objections of philosophers from the Ancients through Russell to Smart, Grünbaum and Putnam, and physicists such as Barbour and Rovelli.

Also available, my An Introduction to Logic, Using Natural Deduction, Real Arguments, a Little History, and Some Humour (Broadview, 2017)— 2nd (retitled) edition of my Natural DeductionAdopt it for your classes, or buy it to learn logic on your own! It’s inexpensive for a logic text (~$40), and perfect preparation for LSAT, etc.!



For the general reader, I recommend my Leibniz, (Polity Press, 2014), where I give a fresh overview of the great German polymath's thought, with emphasis both on its roots and its contemporary scientific and philosophical relevance.

I gave one of the keynote addresses at the North American Leibniz Society and SELFF conference in Montreal in October 2018, a talk in Paris (at Paris 7) on November 7, and then two talks in Prague on November 8 and 9See conferences and latest news for more.
