I’m a philosopher based in Toronto, and (as of July 1st)* Professor Emeritus at McMaster University, Hamilton (Ontario). I research mainly on early modern natural philosophy and mathematics, the theory of time, and the infinite. See research interests for details. *I began teaching in Nairobi in 1969 (!), so with a 50th anniversary of teaching looming, I figured it was time to concentrate on research and writing.

I have just completed the proofs of a new book on Leibniz, __Monads, ____Composition and Force__**:*** Ariadnean Threads through Leibniz's Labyrinth,* (180,000 words), (Oxford University Press) due out in September (UK) and November (North America). 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.

I am now finishing another book, * The Reality of Time Flow* (~95,000 words) for Springer's

*Frontiers of Science*series. 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.

Recently released! My *An Introduction to Logic, Using Natural Deduction, Real Arguments, a Little History, and Some Humour* (Broadview, 2017)— 2nd (retitled) edition of my *Natural Deduction*. Adopt 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.!

Also of interest to the general reader, 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.

In June 2017 I was invited to three functions in Paris: a conference on Wholes and Parts, where I gave a paper on “Monads as Constituents of Bodies in Leibniz’s Metaphysics”; the PhilMath Intersem run by Notre Dame University with Paris 7, where I spoke on “Mathematics and the Leibnizian actual infinite”, and an *hommage* to Jean-Marie Beyssade at the *Séminaire Descartes. *In March 2018 I was invited to Irvine, CA, where I read a paper on “Monads as Constituents of Bodies in Leibniz’s Metaphysics."
