“The essential point was that Cicero for the first time laid out his political credo in black and white, and I can summarise it in a sentence: that politics is the most noble of all callings (“there is really no other occupation in which human virtue approaches more closely the august function of the gods”); that there is “no nobler motive for entering public life than the resolution not to be ruled by wicked men”; that no individual, or combination of individuals, should be allowed to become too powerful; that politics is a profession, not a pastime for dilettantes (nothing is worse than rule by “clever poets”); that a statesman should devote his life to studying “the science of politics, in order to acquire in advance all the knowledge that it may be necessary for him to use at some future time”; that authority in a state must always be divided; and that of the three known forms of government—monarchy, aristocracy and people—the best is a mixture of all three, for each one taken on its own can lead to disaster: kings can be capricious, aristocrats self-interested, and “an unbridled multitude enjoying unwonted power more terrifying than a conflagration or a raging sea.”
