We now proceed to place before the reader a short statement of the most striking characteristics of the ethical philosophy of Aristotle as they are set forth in that compact little book, the _Nicomachean Ethics_. And the first observation proper to make here is the extreme practicality that appears not more in the general colour and tone than in the individual chapters and paragraphs of this remarkable volume. In criticising the sermons delivered in our Christian pulpits we are accustomed to distinguish between doctrinal and practical preaching, and to believe that while, in Scotland at least, the former is the more popular and the more easy, the latter is always the more difficult and the more efficient style of moral address. Now what we have to say of Aristotle, as he appears in the _Ethics_, is that he is not a mere {142} writer on ethics, an acute speculator or a subtle casuist, but he presents himself with all the seriousness of a preacher, and an eminently practical preacher. No doubt in this capacity he must be regarded both by natural genius and in the general tone of his ethical writings as second to his great master Plato; but his influence on the moral culture of the world has not for that reason been less. A large class of men, especially in this practical country, are apt to suspect Plato of nonsense; and these are unwilling to take advice in the affairs of common life from a man who, in his flights of ideal constructiveness, so far transcends the narrow range of their own hard-faced realism. But Aristotle is a man whom no man can suspect of nonsense. He takes what lies before him, and in the most cool practical way conceivable proceeds to analyse it, and to spell out its significance. He is not ambitious--at least not in the department of morals--of piling a grand system, or of tabulating an exhaustive scheme. He is a practical man, as much as you or I am, and sees with marked distinctness always what lies in his way. There is no fear that under his guidance you will lose yourself in a mist or be carried off your feet in a balloon. He is therefore peculiarly fitted for being put forward as a lay-preacher to a British public; and the Oxford scholars have done good service to the English youth by giving his famous work on Ethics such a prominent place among classical books of the first rank. He is as sensible as Dr. Paley, and a great deal more profound; while, on the other hand, it never occurs to him that it is necessary to prepare the way for a plain practical discourse on the conduct of life by abstract discussions {143} on the liberty of the will and the responsibility of free agents. This omission Principal Grant considers a weakness; I consider it a sign of good sense, or, at all events, a remarkable piece of good luck. He assumes morality in the moral world, just as he assumes light and air and water in the physical; he describes a moral man with strong lines and
