 In 1976 the Wellington group ran a week-long logic school, coinciding with Lewis’s stay. Epstein did much of the organizing. Hughes lectured on modal logic and Cresswell on the formal semantics of natural languages—his groundbreaking book Logics and Languages had appeared in 1973. Numerous other group members and visitors lectured on their research. The school ‘brought out into the open … a wide variety of quite exciting work … that had in fact been building up over quite a period of time’, Malcolm said. The Vic logicians were surprised by the large number of enrolments in the school—academics and students from New Zealand, Australia, and beyond. It was a spectacular shop-window, heaped with New Zealand logic. Malcolm later described the school as the Wellington group’s ‘coming-of-age’.
