John MacFarlane is an American professor of philosophy at the University of California, Berkeley[2] interested in logic and metaphysics.

[6] With respect to the normativity of logic for human thought, MacFarlane defends a certain claim made by Frege, a German mathematician and logician.

MacFarlane argues that the systems are indeed comparable, because both thinkers Kant and Frege define logic fundamentally by its generality as a central characteristic.

(2004), MacFarlane turns to a problem raised by Gilbert Harman of the fundamental relationship between logic and human thought.

Assessment Sensitivity has been extensively reviewed in philosophical journals,[10] and has been the subject of a book symposium with Diana Raffman, Jason Stanley, and Crispin Wright.
