Abstract

The use of mathematical models in philosophy is largely neutral over the extent of experimental input. They can figure in an entirely armchair methodology, but they can also play the sort of role they do in physics, economics, and other natural and social sciences. Andrea Bianchi’s description of the starting‐point of philosophy as “empirical data” also suggests a special connection between philosophy and the natural sciences. Many contemporary philosophers describe themselves as naturalists. Naturalists typically criticize some traditional forms of philosophy as insufficiently scientific, because they ignore experimental tests. Naturalism tries to condense the scientific spirit into a philosophical theory. Penelope Maddy rightly emphasizes the weirdness of the idea, found in some contemporary internalist epistemology, that introspection has epistemic priority over perception, but her central objection is to demands on the Plain Inquirer to justify her methods “from scratch.”
