[Footnote: The quotation is from Quinet’s “Ahasvérus” (first published 1833), that strange _Welt-gedicht_, which the author himself described as “l’histoire du monde, de Dieu dans le monde, et enfin du doute dans le monde,” and which, with Faust, probably suggested the unfinished but in many ways brilliant performance of the young Spaniard, Espronceda--_El Diablo Mundo_.] It is better to be lost than to be saved all alone; and it is a wrong to one’s kind to wish to be wise without making others share our wisdom. It is, besides, an illusion to suppose that such a privilege is possible, when everything proves the solidarity of individuals, and when no one can think at all except by means of the general store of thought, accumulated and refined by centuries of cultivation and experience. Absolute individualism is an absurdity. A man may be isolated in his own particular and temporary _milieu_, but every one of our thoughts or feelings finds, has found, and will find, its echo in humanity. Such an echo is immense and far-resounding in the case of those representative men who have been adopted by great fractions of humanity as guides, revealers, and reformers; but it exists for everybody. Every sincere utterance of the soul, every testimony faithfully borne to a personal conviction, is of use to some one and some thing, even when you know it not, and when your mouth is stopped by violence, or the noose tightens round your neck. A word spoken to some one preserves an indestructible influence, just as any movement whatever may be metamorphosed, but not undone. Here, then, is a reason for not mocking, for not being silent, for affirming, for acting. We must have faith in truth; we must seek the true and spread it abroad; we must love men and serve them. April 9, 1868.--I have been spending three hours over Lotze’s big volume (“Geschichte der Aesthetikin Deutschland”). It begins attractively, but the attraction wanes, and by the end I was very tired of it. Why? Because the noise of a mill-wheel sends one to sleep, and these pages without paragraphs, these interminable chapters, and this incessant, dialectical clatter, affect me as though I were listening to a word-mill. I end by yawning like any simple non-philosophical mortal in the face of all this heaviness and pedantry. Erudition, and even thought, are not everything. An occasional touch of esprit, a little sharpness of phrase, a little vivacity, imagination, and grace, would spoil neither. Do these pedantic books leave a single image or formula, a single new or striking fact behind them in the memory, when one puts them down? No; nothing but confusion and fatigue. Oh for clearness, terseness, brevity! Diderot, Voltaire, and even Galiani!
