De Sanctis, whom I have quoted already, and who speaks, I believe, with rather more authority than any other modern Italian critic, and certainly with great clearness and acuteness, does not commit himself to specific praise of Leopardi's work. But he seems to regard him as an important expression, if not force or influence, and he has some words about him, at the close of his “History of Italian Literature”, which have interested me, not only for the estimate of Leopardi which they embody, but for the singularly distinct statement which they make of the modern literary attitude. I should not, myself, have felt that Leopardi represented this, but I am willing that the reader should feel it, if he can. De Sanctis has been speaking of the Romantic period in Italy, when he says: “Giacomo Leopardi marks the close of this period. Metaphysics at war with theology had ended in this attempt at reconciliation. The multiplicity of systems had discredited science itself. Metaphysics was regarded as a revival of theology. The Idea seemed a substitute for providence. Those philosophies of history, of religion, of humanity, had the air of poetical inventions.... That reconciliation between the old and new, tolerated as a temporary political necessity, seemed at bottom a profanation of science, a moral weakness.... Faith in revelation had been wanting; faith in philosophy itself was now wanting. Mystery re-appeared. The philosopher knew as much as the peasant. Of this mystery, Giacomo Leopardi was the echo in the solitude of his thought and his pain. His skepticism announced the dissolution of this theologico-metaphysical world, and inaugurated the reign of the arid True, of the Real. His songs are the most profound and occult voices of that laborious transition called the nineteenth century. That which has importance is not the brilliant exterior of that century of progress, and it is not without irony that he speaks of the progressive destinies of mankind. That which has importance is the exploration of one's own breast, the inner world, virtue, liberty, love, all the ideals of religion, of science, and of poetry--shadows and illusions in the presence of reason, yet which warm the heart, and will not die. Mystery destroys the intellectual world; it leaves the moral world intact. This tenacious life of the inner world, despite the fall of all theological and metaphysical worlds, is the originality of Leopardi, and gives his skepticism a religious stamp. ... Every one feels in it a new creation. The instrument of this renovation is criticism.... The sense of the real continues to develop itself; the positive sciences come to the top, and cast out all the ideal and systematic constructions. New dogmas lose credit. Criticism remains intact. The patient labor of analysis begins again.... Socialism re-appears in the political order, positivism in the intellectual order. The word is no longer liberty, but justice. ... Literature also undergoes transformation.
