settlement was arrived at, which continues in operation up to the present hour. There can be no question, however, that the first of the methods named would have been the surest. But because extreme measures have in them an element of greatness and nobility, a weak republic, so far from knowing how to use this first method, can with difficulty be brought to employ even the second. This, as I said at the beginning, is the kind of blunder made by the princes of our times when they have to decide on matters of moment, from their not considering how those men acted who in ancient days had to determine under like conditions. For the weakness of the present race of men (the result of their enfeebling education and their ignorance of affairs), makes them regard the methods followed by the ancients as partly inhuman and partly impracticable. Accordingly, they have their own newfangled ways of looking at things, wholly at variance with the true, as when the sages of our city, some time since, pronounced that Pistoja was to be held by feuds and Pisa by fortresses , not perceiving how useless each of these methods is in itself.
Having spoken of fortresses already at some length, I shall not further refer to them here, but shall consider the futility of trying to hold subject cities by keeping them divided. In the first place, it is impossible for the ruling power, whether prince or republic, to be friends with both factions. For wherever there is division, it is human nature to take a side, and to favour one party more than another. But if one party in a subject city be unfriendly to you, the consequence will be that you will lose that city so soon as you are involved in war, since it is impossible for you to hold a city where you have enemies both within and without.
