be more easily altered, until the whole fabric of government is entirely subverted, which happened in the government of Thurium; for the law being that they should continue soldiers for five years, some young men of a martial disposition, who were in great esteem amongst their officers, despising those who had the management of public affairs, and imagining they could easily accomplish their intention, first endeavoured to abolish this law, with a view of having it lawful to continue the same person perpetually in the military, perceiving that the people would readily appoint them. Upon this, the magistrates who are called counselors first joined together with an intention to oppose it but were afterwards induced to agree to it, from a belief that if that law was not repealed they would permit the management of all other public affairs to remain in their hands; but afterwards, when they endeavoured to restrain some fresh alterations that were making, they found that they could do nothing, for the whole form of government was altered into a dynasty of those who first introduced the innovations. In short, all governments are liable to be destroyed either from within or from without; from without when they have for their neighbour a state whose policy is contrary to theirs, and indeed if it has great power the same thing will happen if it is not their neighbour; of which both the Athenians and the Lacedaemonians are a proof; for the one, when conquerors everywhere destroyed the oligarchies; the other the democracies. These are the chief causes of revolutions and dissensions in governments. CHAPTER VIII
