"Literary history is, in its profoundest significance, psychology, the study, the history of the soul"; and literary criticism is, with our author, nothing less than the interior history of peoples. Whether we happen to agree or to disagree with his personal sympathies, which lie altogether with liberalism and whether his interpretation of these complex movements be accepted or rejected by future criticism, it is at least unquestionable that his estimate of his science is the right one, and that his method is the right one, and that no one stands beside Brandes as an exponent. The historical movement of the years 1800 to 1848 is here likened to a drama, of which six different literary groups represent the six acts. The first three acts incorporate the reaction against progress and liberty. They are, first, the French Emigrant Literature, inspired by Rousseau; secondly, the semi-Catholic Romantic school of Germany, wherein the reaction has separated itself more thoroughly from the contemporary struggle for liberty, and has gained considerably in depth and vigour; and, thirdly, the militant and triumphant reaction as shown in Joseph de Maistre, Lamennais, Lamartine and Victor Hugo, standing out for pope and monarch. The drama of reaction has here come to its climax; and the last three acts are to witness its fall, and the revival, in its place, of the ideas of liberty and of progress. "It is one man, Byron, who produces the revulsion in the great drama." And Byron and his English contemporaries, Wordsworth, Coleridge, Scott, Keats and Shelley, hold the stage in the fourth act, "Naturalism in England." The fifth act belongs to the Liberal movement in France, the "French Romantic School," including the names of Lamennais, Lamartine and Hugo in their second phase; and also those of De Musset and George Sand. The movement passes from France into "Young Germany," where the sixth act is played by Heine, Ruge, Feuerbach and others; and the ardent revolutionary writers of France and of Germany together prepare for the great political transformation of 1848. _I.--The Emigrant Literature_ At the beginning of our period, France was subjected to two successive tyrannies: those, namely, of the Convention and of the Empire, both of which suppressed all independent thought and literature. Writers were, perforce, emigrants beyond the frontiers of French power, and were, one and all, in opposition to the Reign of Terror, or to the Napoleonic tyranny, or to both; one and all they were looking forward to the new age which should come.
