Madame de Staël's _Germany_, one of the most famous of the "national character" books, begins with a description of the German landscape. But though nobody, from Ovid in exile down to Madame de Staël, questions the general significance of place, time, and circumstances as affecting the nature of a literary product, when we come to the exact and as it were mathematical demonstration of the precise workings of these physical influences, our generation is distinctly more cautious than were the literary critics of forty years ago. Indeed, it is a hundred years since Fisher Ames, ridiculing the theory that climate acts directly upon literary products, said wittily of Greece: "The figs are as fine as ever, but where are the Pindars?" The theory of race, in particular, has been sharply questioned by the experts. "Saxon" and "Norman," for example, no longer seem to us such simple terms as sufficed for the purpose of Scott's _Ivanhoe_ or of Thierry's _Norman Conquest_, a book inspired by Scott's romance. The late Professor Freeman, with characteristic bluntness, remarked of the latter book: "Thierry says at the end of his work that there are no longer either Normans or Saxons except in history.... But in Thierry's sense of the word, it would be truer to say that there never were 'Normans' or 'Saxons' anywhere, save in the pages of romances like his own." There is a brutal directness about this verdict upon a rival historian which we shall probably persist in calling "Saxon"; but it is no worse than the criticisms of Matthew Arnold's essay on "The Celtic Spirit" made to-day by university professors who happen to know Old Irish at first hand, and consequently consider Arnold's opinion on Celtic matters to be hopelessly amateurish. The wiser scepticism of our day concerning all hard-and-fast racial distinctions has been admirably summed up by Josiah Royce. "A race psychology," he declares, "is still a science for the future to discover.... We do not scientifically know what the true racial varieties of mental type really are. No doubt there are such varieties. The judgment day, or the science of the future, may demonstrate what they are. We are at present very ignorant regarding the whole matter."
