  In mid-1959, while bushwalking in Australia, he met Jack Smart (then in Adelaide, later a colleague at the Australian National University and good bushwalking friend thereafter) who encouraged him to go to Princeton for graduate work, as opposed to the then more usual choice of UK universities like Cambridge. At Smart’s urging, “as a brash young man” Sylvan travelled to Princeton with a Fulbright scholarship for doctoral studies under Alonzo Church to “repair and renovate a derelict philosophy of science” (Sylvan 2000a, 7). After two and a half years he was awarded an MA from Princeton University but left before completing his PhD, dissatisfied with the intellectual climate there and subsequent lack of progress on his project. (He later received a PhD from Princeton in 1980 for chapter one of Routley 1980.) He accepted a lectureship at Sydney University in 1962 where he began lecturing undergraduates in logic—introducing modern Russellian theory, displacing John Anderson’s long insistence on Aristotelian theory. There he met Val Plumwood (then Val Macrae, later Val Routley) and, in 1964, they moved to the University of New England where Sylvan joined Len Goddard and a growing department—the first to have begun teaching modern logic in Australia under Goddard in 1957. Goddard and Sylvan founded the first Australian Masters program in logic and formed the Australasian Association of Logic, and with Len Goddard, David Londey, Ross Brady, Malcolm Rennie and Val Plumwood, he developed what became known as the New England Group—working on non-classical logic and paradoxes, among other things—but Goddard left a few years later, returning to St Andrews in Scotland. In 1967, with a year’s sabbatical owing, Sylvan and Plumwood married (with Plumwood taking the name Routley) and they drove from the University to St Andrews to continue work with Goddard (traversing northern Australia, shipping the car from Darwin to Singapore, then overland into India and Pakistan, through the Middle East and Eastern Europe). Upon return, in 1968, Sylvan took a position at Monash University before being appointed to a Senior Fellowship in Philosophy in the Research School of Social Sciences at the Australian National University (ANU) in 1971, where he remained for the rest of his career. With only postgraduate students to supervise, his days teaching undergraduates was at an end. A number of researchers from the New England Group subsequently joined him there and, with the addition of Bob Meyer, Graham Priest, and others, a group re-formed around Sylvan at the ANU—the well-known Canberra Logic Group that went on to pioneering research in non-classical, especially relevant, logic. Through his contribution to the formation of research groups that were both innovative and productive, Sylvan influenced a whole generation of Australian philosophers and logicians. (For more on this history of modern logic in Australia, cf. Routley 1984c, Goddard 1992, and Brady and Mortensen 2014.)
