The issue of an invasion is generally decided by this political aptitude, and the consequences of conquest always depend on it. Subjection to a people of a higher capacity for government is of itself no misfortune; and it is to most countries the condition of their political advancement. The Greeks were more highly cultivated than the Romans, the Gauls than the Franks; yet in both cases the higher political intelligence prevailed. For a long time the English had, perhaps, no other superiority over the Irish; yet this alone would have made the conquest a great blessing to Ireland, but for the separation of the races. Conquering races necessarily bring with them their own system of government, and there is no other way of introducing it. A nation can obtain political education only by dependence on another. Art, literature, and science may be communicated by the conquered to the conqueror; but government can be taught only by governing, therefore only by the governors; politics can only be learnt in this school. The most uncivilised of the barbarians, whilst they slowly and imperfectly learned the arts of Rome, at once remodelled its laws. The two kinds of civilisation, social and political, are wholly unconnected with each other. Either may subsist, in high perfection, alone. Polity grows like language, and is part of a people's nature, not dependent on its will. One or the other can be developed, modified, corrected; but they cannot be subverted or changed by the people itself without an act of suicide. Organic change, if it comes at all, must come from abroad. Revolution is a malady, a frenzy, an interruption of the nation's growth, sometimes fatal to its existence, often to its independence. In this case revolution, by making the nation subject to others, may be the occasion of a new development. But it is not conceivable that a nation should arbitrarily and spontaneously cast off its history, reject its traditions, abrogate its law and government, and commence a new political existence. Nothing in the experience of ages, or in the nature of man, allows us to believe that the attempt of France to establish a durable edifice on the ruins of 1789, without using the old materials, can ever succeed, or that she can ever emerge from the vicious circle of the last seventy years, except by returning to the principle which she then repudiated, and by admitting, that if States would live, they must preserve their organic connection with their origin and history, which are their root and their stem; that they are not voluntary creations of human wisdom; and that men labour in vain who would construct them without acknowledging God as the artificer.
