If the topic of my address was the history of political science, the highest and the largest place would belong to Plato and Aristotle. The _Laws_ of the one, the _Politics_ of the other, are, if I may trust my own experience, the books from which we may learn the most about the principles of politics. The penetration with which those great masters of thought analysed the institutions of Greece, and exposed their vices, is not surpassed by anything in later literature; by Burke or Hamilton, the best political writers of the last century; by Tocqueville or Roscher, the most eminent of our own. But Plato and Aristotle were philosophers, studious not of unguided freedom, but of intelligent government. They saw the disastrous effects of ill-directed striving for liberty; and they resolved that it was better not to strive for it, but to be content with a strong administration, prudently adapted to make men prosperous and happy. Now liberty and good government do not exclude each other; and there are excellent reasons why they should go together. Liberty is not a means to a higher political end. It is itself the highest political end. It is not for the sake of a good public administration that it is required, but for security in the pursuit of the highest objects of civil society, and of private life. Increase of freedom in the State may sometimes promote mediocrity, and give vitality to prejudice; it may even retard useful legislation, diminish the capacity for war, and restrict the boundaries of Empire. It might be plausibly argued that, if many things would be worse in England or Ireland under an intelligent despotism, some things would be managed better; that the Roman Government was more enlightened under Augustus and Antoninus than under the Senate, in the days of Marius or of Pompey. A generous spirit prefers that his country should be poor, and weak, and of no account, but free, rather than powerful, prosperous, and enslaved. It is better to be the citizen of a humble commonwealth in the Alps, without a prospect of influence beyond the narrow frontier, than a subject of the superb autocracy that overshadows half of Asia and of Europe. But it may be urged, on the other side, that liberty is not the sum or the substitute of all the things men ought to live for; that to be real it must be circumscribed, and that the limits of circumscription vary; that advancing civilisation invests the State with increased rights and duties, and imposes increased burdens and constraint on the subject; that a highly instructed and intelligent community may perceive the benefit of compulsory obligations which, at a lower stage, would be thought unbearable; that liberal progress is not vague or indefinite, but aims at a point where the public is subject to no restrictions but those of which it feels the advantage; that a free country may be less capable of doing much for the advancement of religion, the prevention of vice, or
