Discourses on Livy

That, commonly, fortresses do much more harm than good.

To the wise men of our day it may seem an oversight on the part of the Romans, that, when they sought to protect themselves against the men of Latium and Privernum, it never occurred to them to build strongholds in their cities to be a curb upon them, and insure their fidelity, especially when we remember the Florentine saying which these same wise men often quote, to the effect that Pisa and other like cities must be held by fortresses. Doubtless, had those old Romans been like-minded with our modern sages, they would not have neglected to build themselves fortresses, but because they far surpassed them in courage, sense, and vigour, they refrained. And while Rome retained her freedom, and adhered to her own wise ordinances and wholesome usages, she never built a single fortress with the view to hold any city or province, though, sometimes, she may have suffered those to stand which she found already built.
