October 2014   This semester, I am teaching “Rival Defenses of American Capitalism” at Brown.   On October 17 at the University of Pittsburgh’s Center for Philosophy of Science, I will speak on induction in the Socratic tradition.   I’m back to writing my book on the history of induction, Socrates to Popper. I’m now writing up the period from Bacon to Whewell. Adoption of Bacon’s method by Harvey and Boyle is very underappreciated.

How are the right to be angry, the right to vote, and the right to associate with those of your choosing related? Why there do we use the word “right?”

The main theme of my research is that the philosophical problem of induction is an artifact of a bad turn taken in the early 19th century, by which induction came to be conceived as a logic of propositional inference that depends on a suppressed uniformity principle. In antiquity and from Bacon to Whewell, induction was instead conceived as a logic of classification.


Since 2012, I have been teaching one seminar every fall for the Political Theory Project at Brown University. Two have been on 20th-century defenders of capitalism, one on Ayn Rand specifically. I taught similar seminars and ones on history of scientific method for several years at Stanford University. In 2011, I taught a course on history of science at Stevens Institute of Technology.

Students’ Comments

“By far the most challenging and most rewarding course I’ve taken thus far at Stanford.” • “One of the best classes I’ve taken at Brown!” • “I’ve always liked precision of logic but wasn’t aware how it could be applied to morality.” • “It’s one of those classes that changes the way you look at things.”
