John N. Martin studied philosophy at the University of California, received his doctorate from the University of Toronto, and spent his career teaching philosophy and logic at the University of Cincinnati. Research areas: formal semantics, philosophical linguistics, and the history of logic. Books: Elements of Formal Semantics (1987) and Themes in Neoplatonic and Aristotelian Logic (Ashgate 2004).
Martin has offered a substantive treatment of an important but often overlooked text . . . Martin's book is a significant contribution to scholarship especially on the logic of the Port Royal Logic, and will, no doubt, generate more interest in this influential text-interest it richly deserves. - Notre Dame Philosophical Reviews
