"I think a website takes on the personality of the one who built it."
- Dave, Webmaster, AllState Insurance Co.

Well, I agree with Dave. So my website is like my personality: stable and anachronistic. 

Research Interests

History of physics and philosophy of nature; philosophical implications of the history of mathematics; natural philosophy in the constitution of modernity, thus concentration on early modern philosophy in relation to the preceding tradition.

Graduate Courses Taught Since 1990

  • Phil. 827: Quantum Physics and Philosophy of Nature
  • Phil. 753: Philosophy of Nature: Aristotle's Physics
  • Phil. 781: Descartes's Science: Regulae, Le Monde, Discourse, Principles.
    Mathematization of nature: what is gained, what is lost? Traditional cosmology of natural goodness vs Descartes's cosmogony of natural indifference (eidetic vs genetic accounts). Method and mastery vs theoria and wonder. The problem of judgment and causality. Divine creation of the eternal truths and the foundations of physics.
  • Phil. 715: Descartes's Passions of the Soul
    A study of natural-philosophic notions at work in the origins of modern psychology, and an attempt to make sense of a book that is as subtle and obscure as it is seminal and radical.
  • Phil. 757: Newton's Principia
    A study of natural-philosophic and historical-mathematical issues in the Principia: the relation between sensible and intelligible; causality, reductionism, determinism; the species-neutrality of Newton's law of gravitation and of the resulting particles-and-forces model of nature ("the mechanical view"); Newton's distinctive geometry and its supersession by analytical technique.
  • Phil. 810: Wholes, Parts, and Laws of Motion
    A comparison of Descartes's laws of nature and Newton's laws of motion with regard to their differing implications concerning body, motion, and causality.
  • Phil. 796: Leibniz: Physics and Metaphysics
    A study of Leibniz's attempt to harmonize mechanism and teleology. Special attention is given to the concept of natural form in Aristotle, against which background Leibniz's true position on mastery of nature comes into focus: this is the best of all possible worlds in part because it is amenable to limitless transformation by human agency.
  • Phil. 825: Modern Political Thought: Machiavelli, Hobbes, Rousseau
    A reading of The Prince, Leviathan, and Second Discourse in order to discern the development of the non-teleological understanding of the human that links the three thinkers.
  • Phil. 790: Mathematical Thought Ancient and Modern
    A comparison of Euclidean and Cartesian geometry, using David Lachterman, The Ethics of Geometry.
  • Phil. 792: The Concept of Number
    A comparison of Diophantus' Arithmetic and Vieta's Analytic Art; based on Jacob Klein, Greek Mathematical Thought and the Origin of Algebra
  • Phil. 601: Philosophy of Science for graduate students in the School of Nursing
    A study of what it means to be scientific according to the current consensus, and of the difficulties in attempting to be scientific in dealing with human beings.
