Modernism had a long run, more than a century indeed. Its duration and variety make it almost impossible to define. When Cyril Connolly gave us his 100 Key Books of the Modern Movement, he included several works and authors that seem only doubtfully Modernist (Betjeman or Somerset Maugham, for example). As his subtitle suggests, Peter Gay regards Modernists as being attracted by heresy; yet long before Modernism may be held to have died, the heretics were those who stood out against it.
Even some of the most difficult Modernists had their own doubts. Gay quotes from Nathalie Sarraute’s essay ‘L’Ere de Soupcon’, but doesn’t mention her observation that ‘the traditional novel has an eternal freshness’.
