But Leopardi was so essentially the poet that, in spite of his growing disdain of the pathetic and the eloquent, he became not infrequently the dupe of his own imagination. That which he took for the fruit of deduction was probably little more than ordinary hypochondria, and in turning as he did to other work, he was never able to free himself entirely from the jealous influence of the muse. He was, from a variety of causes, very miserable himself, and his belief in universal misery amounted very nearly to a mania. His logic reduced itself to the paraphrase of an axiom, "I am, therefore I suffer," and the suffering which he experienced was not, he was very sure, limited solely to himself. It was, he considered, the garment and appanage of every sentient being. In this he was perfectly correct, but his error consisted in holding all cases to be equally intense, and in imagining that means might be devised which would at once do away with or, at least, lessen the evil. Patience and resignation he had already suggested, but naturally without appreciable success; indeed, the regeneration of man, he clearly saw, was not to be brought about through verse, and he turned therefore to philosophy with a fixity of purpose, which was strengthened by the idea that he could work therein another revolution. This was in 1825. Leopardi at that time was in his twenty-seventh year, and the task to which he then devoted himself was, he said, to be the sad ending of a miserable life. His intention was to run the bitter truth to earth, to learn the obscure destinies of the mortal and the eternal, to discover the wherefore of creation, and the reason of man's burden of misery. "I wish," he said, "to dig to the root of nature and seek the aim of the mysterious universe, whose praises the sages sing, and before which I stand aghast." Forthwith, then, in the "Operette Morale," Leopardi began a resolute, if poetic, siege against every form of illusion. His philosophy, however, provoked no revolution, nor can it be even said that he discovered any truth more bitter than the old new ones, which antiquity had unearthed before him. His work, nevertheless, sent the old facts spinning into fresh and novel positions, and is to be particularly admired for the artistic manner in which it handles the most stubborn topics. The starting point of each of his arguments is that life is evil; to any objection, and the objections that have been made are countless, Leopardi has one invariable reply, "All that is advanced to the contrary is the result of illusion." "But supposing life to be painless," some one presumably may interject, whereupon Leopardi, with the air of an oracle, too busy with weighty matters to descend to chit-chat on the weather, will answer tersely, "Evil still."
