Of these years of travel, however, the four years spent at Berlin were by far the most important. “It was at Heidelberg and Berlin,” says M. Scherer, “that the world of science and speculation first opened on the dazzled eyes of the young man. He was accustomed to speak of his four years at Berlin as ‘his intellectual phase,’ and one felt that he inclined to regard them as the happiest period of his life. The spell which Berlin laid upon him lasted long.” Probably his happiness in Germany was partly owing to a sense of reaction against Geneva. There are signs that he had felt himself somewhat isolated at school and college, and that in the German world his special individuality, with its dreaminess and its melancholy, found congenial surroundings far more readily than had been the case in the drier and harsher atmosphere of the Protestant Rome. However this may be, it is certain that German thought took possession of him, that he became steeped not only in German methods of speculation, but in German modes of expression, in German forms of sentiment, which clung to him through life, and vitally affected both his opinions and his style. M. Renan and M. Bourget shake their heads over the Germanisms, which, according to the latter, give a certain “barbarous” air to many passages of the Journal. But both admit that Amiel’s individuality owes a great part of its penetrating force to that intermingling of German with French elements, of which there are such abundant traces in the “Journal Intime.” Amiel, in fact, is one more typical product of a movement which is certainly of enormous importance in the history of modern thought, even though we may not be prepared to assent to all the sweeping terms in which a writer like M. Taine describes it. “From 1780 to 1830,” says M. Taine, “Germany produced all the ideas of our historical age, and during another half-century, perhaps another century, _notre grande affaire sera de les repenser_.” He is inclined to compare the influence of German ideas on the modern world to the ferment of the Renaissance. No spiritual force “more original, more universal, more fruitful in consequences of every sort and bearing, more capable of transforming and remaking everything presented to it, has arisen during the last three hundred years. Like the spirit of the Renaissance and of the classical age, it attracts into its orbit all the great works of contemporary intelligence.” Quinet, pursuing a somewhat different line of thought, regards the worship of German ideas inaugurated in France by Madame de Staël as the natural result of reaction from the eighteenth century and all its ways. “German systems, German hypotheses, beliefs, and poetry, all were eagerly welcomed as a cure for hearts crushed by the mockery of Candide and the materialism of the Revolution.... Under the Restoration France continued to study German philosophy and poetry with profound veneration and submission.
