While Lucretius was engaged in this work, he fell into a state of insanity, occasioned, as is supposed, by a philtre, or love-potion, given him by his wife Lucilia. The complaint, however, having lucid intervals, he employed them in the execution of his plan, and, soon after it was finished, laid violent hands upon himself, in the forty-third year of his age. This fatal termination of his life, which perhaps proceeded from insanity, was ascribed by his friends and admirers to his concern for the banishment of one Memmius, with whom he was intimately connected, and for the distracted state of the republic. It was, however, a catastrophe which the principles of Epicurus, equally erroneous and irreconcilable to resignation and fortitude, authorized in particular circumstances. Even Atticus, the celebrated correspondent of Cicero, a few years after this period, had recourse to the same desperate expedient, by refusing all sustenance, while he laboured under a lingering disease. It is said that Cicero revised the poem of Lucretius after the death of the author, and this circumstance is urged by the abettors of atheism, as a proof that the principles contained in the work had the sanction of his authority. But no inference in favour of Lucretius’s doctrine can justly be drawn from this circumstance. (70) Cicero, though already sufficiently acquainted with the principles of the Epicurean sect, might not be averse to the perusal of a production, which collected and enforced them in a nervous strain of poetry; especially as the work was likely to prove interesting to his friend Atticus, and would perhaps afford subject for some letters or conversation between them. It can have been only with reference to composition that the poem was submitted to Cicero’s revisal: for had he been required to exercise his judgment upon its principles, he must undoubtedly have so much mutilated the work, as to destroy the coherency of the system. He might be gratified with the shew of elaborate research, and confident declamation, which it exhibited, but he must have utterly disapproved of the conclusions which the author endeavoured to establish. According to the best information, Lucretius died in the year from the building of Rome 701, when Pompey was the third time consul. Cicero lived several years beyond this period, and in the two last years of his life, he composed those valuable works which contain sentiments diametrically repugnant to the visionary system of Epicurus. The argument, therefore, drawn from Cicero’s revisal, so far from confirming the principle of Lucretius, affords the strongest tacit declaration against their validity; because a period sufficient for mature consideration had elapsed, before Cicero published his own admirable system of philosophy. The poem of Lucretius, nevertheless, has been regarded as the bulwark of atheism--of atheism, which, while it impiously arrogates the support of reason, both reason and nature disclaim.
