Montesquieu now went on with his studies with an enlarged mind. He would appear, before he started on his travels, to have already formed the project of writing a great work on the Spirit of the Laws. But in 1784 he published a smaller book, the "Greatness and Decadence of the Romans." It is said that this essay was composed of a part of the material collected for the Spirit of the Laws, and was published separately in order not to give the Romans too large a place in the more important work. This has been doubted, but there is nothing either in the subject or in the treatment to make it improbable. Nor is it important, so long as between the two books there is unity of purpose and agreement of method. The "Greatness and Decadence of the Romans" is a study of philosophic history. In form it is not unlike Machiavelli's Discourses on the first ten books of Livy. That remarkable work would have been most profitable reading for Frenchmen of the eighteenth century, as it must be in all times for students of the science of politics. Of republics Machiavelli had more experience than Montesquieu. Both considered the republican form of government the most desirable; both thought it impossible without the preservation of substantial equality of property among the citizens. Montesquieu, who knew more of monarchy than Machiavelli, had also more faith in it. Both hated the Rule of the Roman Church. [Footnote: Machiavelli, ii. 210. Montesq., ii. 136, 140. Mach., ii. 130.] The Frenchman excels the Italian in practical wisdom; he is also more brilliant. By his brilliancy he may sometimes have been led away, but I think not often. While we feel in reading Voltaire that the sparkling point is often the cause of the saying, with Montesquieu we are generally struck with the weight of thought in what we read. "The tyranny of a prince," says Montesquieu, "does not bring him nearer to ruin, than indifference to the public good brings a republic. The advantage of a free state is that the revenues are better administered--but how if they are worse? The advantage of a free state is that there are no favorites; but when that is not the case, and when instead of enriching the prince's friends and relations, all the friends and relations of all those who share in the government have to be enriched, all is lost; the laws are evaded more dangerously than they are violated by a prince, who, being always the greatest citizen of a state, has the most interest in its preservation."[Footnote: Montesq., ii. 139.]
