G.K. Chesterton's The Man Who Was Thursday (1908) purports to differentiate modernist insiders and anti-modernist outsiders; and to expound the difference in terms of religious belief, art and politics. According to the book's spokesman for modernism, Lucian Gregory, modernists are anarchist-terrorists, whose priority involves 'the lawlessness of art and the art of lawlessness'...Opposed to these claims, which Chesterton calls the product of 'dirty modern thinkers' is Chesterton's protagonist Gabriel Syme, who apparently is outside modernism. He is 'a poet of law' and order and respectability -- a detective, in other words! -- and he becomes an undercover agent in order to hunt down 'Sunday', the secret head of a powerful international modernist-anarchist-terrorist group.
