 On the other side of the world, at the 1968 Joint Session of the Aristotelian Society and Mind Association at Liverpool University, Prior attended a symposium on ‘What Actually Exists?’, given by Peter Geach and Robert Stoothoff. He was impressed by Stoothoff, saying approvingly in a letter to Montgomery that the young American had ‘done a lot of fighting for logic’. Stoothoff was unexpectedly contacted by Canterbury and offered Shorter’s—Prior’s—chair. He accepted, arriving in Christchurch in 1970. (Shorter was moving on to a fellowship at Lincoln College, Oxford.) Also in 1970, the Czech logician Pavel Tichý accepted a senior lectureship in philosophy at the University of Otago. Tichý had fled his native Prague soon after Soviet tanks took command of the streets in 1968. (His escape from East to West was ably assisted by Geoffrey Keene, a logician from Exeter University in the UK (Svoboda et al. 2004: 26).) Once settled in New Zealand Tichý wrote a paper on quantified S5, taking Hughes and Cresswell to task for mis-formalizing a modal principle stated by Prior and von Wright (Tichý 1973, Prior 1955a: 211). Soon he was indulging in the national logical pastime of exploring Priorean temporal logics.
