Martin was part of the first wave of American analytic philosophers; arguably, only Quine (1908–2000), Fitch (1909–1987), and Henry Leonard (1905–67) preceded him. His chronological elders Nelson Goodman (1906–1998) and Wilfrid Sellars (1912–89) were arguably his contemporaries, as they all began their careers in earnest at about the same time, namely right after World War II. Martin's formal treatment of syntax followed Alfred Tarski; of semantics, Rudolf Carnap. Martin was generally well-disposed towards Carnap's work, contributed a long paper to the Schilpp volume on Carnap, and was seen as a disciple. Paradoxically, Martin was a positivist and radical nominalist who also sympathized with process theology and orthodox Christianity.
