I wish I could be equally indulgent to the writers of the eighteenth century, who made their own application of the same theory; but there is, between them and their teachers, too great a difference. While the ancients were attached to the established social system, even to a fault, our moderns were anxious for destruction, and greedy of untried novelties. The former exerted themselves to deduce useful lessons from their theory; the latter have perverted it into a fearful weapon against all rational principles of government, which they stigmatized by every term that mankind holds in horror. To save societies from ruin, the disciples of Voltaire would destroy religion, law, industry, commerce; because, if we believe them, religion is fanaticism; laws, despotism; industry and commerce, luxury and corruption. I have not the slightest intention of entering the field of polemics; I wished merely to direct attention to the widely diverging results of this principle, when applied by Thucydides, or the Abbé Raynal. Conservative in the one, cynically aggressive in the other, it is erroneous in both. The causes to which the downfall of nations is generally ascribed are not the true ones, and whilst I admit that these evils may be rifest in the last stages of dissolution of a people, I deny that they possess in themselves sufficient strength, and so destructive an energy, as to produce the final, irremediable catastrophe.
