At this point one is reminded of Watts-Dunton's definition of the two kinds of humour in The Renascence of Wonder: "While in the case of relative humour that which amuses the humorist is the incongruity of some departure from the laws of convention, in the case of absolute humour it is the incongruity of some departure from the normal as fixed by nature herself." We have our doubts as to the general application of this definition: but it applies so well to Chesterton that it might almost have come off his study walls. What made a series of more than six hundred articles by him acceptable to The Daily News was just the skilful handling of "the laws of convention," and "the normal as fixed by nature herself." On the theory enunciated by Watts-Dunton, everything except the perfect average is absolutely funny, and the perfect average, of course, is generally an incommensurable quantity. Chesterton carefully made it his business to present the eccentricity--I use the word in its literal sense--of most things, and the humour followed in accordance with the above definition. The method was simple. Chesterton invented some grotesque situation, some hypothesis which was glaringly absurd. He then placed it in an abrupt juxtaposition with the normal, instead of working from the normal to the actual, in the usual manner. Just as the reader was beginning to protest against the reversal of his accustomed values, G.K.C. would strip the grotesque of a few inessentials, and, lo! a parable. A few strokes of irony and wit, an epigram or two infallibly placed where it would distract attention from a weak point in the argument, and the thing was complete. By such means Chesterton developed the use of a veritable Excalibur of controversy, a tool of great might in political journalism. These methods, pursued a few years longer, taught him a craftsmanship he could employ for purely romantic ends. How he employed it, and the opinions which he sought to uphold by its means will be the subjects of the following chapters. Chesterton sallied forth like a Crusader against the political and literary Turks who had unjustly come into possession of a part of the heritage of a Christian people. We must not forget that the leading characteristic of a Crusader is his power of invigorating, which he applies impartially to virtues and to vices. There is a great difference between a Crusader and a Christian, which is not commonly realized. The latter attempts to show his love for his enemy by abolishing his unchristianness, the former by abolishing him altogether. Although the two methods are apt to give curiously similar results, the distinction between a Crusader and a Christian is radical and will be considered in greater detail in the course of this study. This study does not profess to be biographical, and only the essential facts of Chesterton's life need be given here. These are, that he was born in London in 1873, is
