James argues somewhere that a style as thick as Hegel's can not be the "authentic mother-tongue of reason." If that is unfair to Hegel, it is a fair revelation of the mind of James. He was an advocate and an exemplar of lucidity of expression, and was always putting to himself and other philosophers the plain question: "Just what do you mean?" But his sharpness of mind, though often aggressive, was never offensive. He seems at times to have dulled the edge of his wit in order not to hurt the other fellow. The editor of the letters has, perhaps wisely, "not included letters that are wholly technical or polemic." Probably the ideas expressed in the technical letters are repeated in James's books. But I should like to see the polemic letters. The editor himself in the act of withholding them has defined their merits: "He rejoiced openly in the controversies which he provoked and engaged in polemics with the good humor and vigor that were the essence of his genius." The touches of polemic writing which appear in the correspondence that is given us reveal this good humor and vigor and make one hungry for more. He was staunch and dexterous in argument and never yielded an inch, but he could stop and laugh at his opponent and at himself. He objected to Huxley's somewhat solemn devotion to "Truth," yet he had a kind of skill in argument that was not unlike Huxley's. He could give a man a smashing blow in the ribs, and even show a quite human irritation, but his exquisite courtesy never failed. His letters to Godkin, of the _Nation_, protesting against unfair criticism of the work of the elder Henry James, are a lesson for critics, and no doubt Godkin's reply was a model of magnanimous contrition.
