Its weapon is advocacy. In pure, serene, absolute controversy the advocate will cheerfully take either side, but even in that less perfect controversy to which (alas!) our fallen nature condemns us, and in which there is some suspicion of real feeling, advocacy easily takes precedence over the statement of truth. And that is one of the delights of controversy, as no one knows better than they who have wasted and enjoyed their lives in this delicious pastime.
I always think that there is an ill done to controversy when the lists are unequally chosen. It demands for its proper exercise fairly equal chances for either side. For instance, one man gets up and says that England would be much better off if no foreign goods came into it, whereupon the other man, scenting a controversy from afar, says: "What about tea?" There at once--at the very issue of the bout--you have a knockout, and that spoils sport. Or again, a man says: "If you want to improve the communications of London you must have wider streets, and you cannot have wider streets without interfering with privileged pieces of property." The moment you begin to talk like that controversy is abominably offended. You might as well play chess with a loaded revolver, or come to the football field with a posse of bravoes.
No, the essence of this admirable exercise is a sort of "picking up sides" which balances the argument. You must give reasonable chances for advocacy to either party. Chalk the lists, face the champions square, and then let go.
I notice a very proper contempt for, and sometimes interference with, that party to a controversy who breaks even the less understood and more subtle rules: for instance, dropping the "Mr." in Politics. You may say of a parliamentarian, "Mr. Biggs was committing political murder when he poured his hidden poison into the sleeping ear of Mr. Higgs." That is all right. It means that old Biggs thought he could get more money by abandoning his leader Higgs. The use of the two "Misters" proves that in your heart you care not a dump which gets the salary, contracts, and perks. But if you say "Biggs won't take office under Higgs because he thinks there's no money in it," that is blackguardly: for it spoils sport.
