by Solon probably had some aristocratic features, though their precise nature is unknown to us. The ancients knew that election by lot was the most democratic of all modes of appointment, seeming to say in the objectionable sense, that 'one man is as good as another.' Plato, who is desirous of mingling different elements, makes a partial use of the lot, which he applies to candidates already elected by vote. He attempts also to devise a system of checks and balances such as he supposes to have been intended by the ancient legislators. We are disposed to say to him, as he himself says in a remarkable passage, that 'no man ever legislates, but accidents of all sorts, which legislate for us in all sorts of ways. The violence of war and the hard necessity of poverty are constantly overturning governments and changing laws.' And yet, as he adds, the true legislator is still required: he must co-operate with circumstances. Many things which are ascribed to human foresight are the result of chance. Ancient, and in a less degree modern political constitutions, are never consistent with themselves, because they are never framed on a single design, but are added to from time to time as new elements arise and gain the preponderance in the state. We often attribute to the wisdom of our ancestors great political effects which have sprung unforeseen from the accident of the situation. Power, not wisdom, is most commonly the source of political revolutions. And the result, as in the Roman Republic, of the co-existence of opposite elements in the same state is, not a balance of power or an equable progress of liberal principles, but a conflict of forces, of which one or other may happen to be in the ascendant. In Greek history, as well as in Plato's conception of it, this 'progression by antagonism' involves reaction: the aristocracy expands into democracy and returns again to tyranny.
