Philosophical Specialties in the Directories
Most individuals listed in the International Directory of Philosophy, Directory of American Philosophers, or International Directory of Philosophy and Philosophers have been assigned up to three subject specialties from the following list of philosophical specialties. Names of individual philosophers may also be used as subject specialties (e.g. Aristotle, Derrida, Hume), though these are too numerous to be easily listed here. We do add new terms, though we avoid doing this until a term is well-established in the secondary literature.
Please note that the purpose of assigning specialties from a limited vocabulary of terms is to facilitate communication among philosophers with common interests. Listings are provided free of charge, and all listings can be updated online.
