The contributors set out to demonstrate the influence of the computer - not just in the philosophy of mind, where the influence has been enormous, but also in epistemology, metaphysics, logic and the philosophy of mathematics. Even ethics and ethical reasoning have been explored through the use of the computer. Indeed, the lead contribution by Nobel Laureate Herbert Simon argues that it is no exaggeration to speak of a computational turn in philosophy to match the much-celebrated (and maligned) linguistic turn of a previous generation. Of particular interest are the examinations of the wide range of applications of computational methods, the innovative instructional computer programs, and the discussions of the ethical implications of computer use.
