As it is improbable that there will soon be another people so free from preoccupations, so gifted, and so fortunate as the Greeks, or capable in consequence of so well exemplifying humanity, so also it is improbable that a philosopher will soon arise with Aristotle’s scope, judgment, or authority, one knowing so well how to be both reasonable and exalted. It might seem vain, therefore, to try to do afresh what has been done before with unapproachable success; and instead of writing inferior things at great length about the Life of Reason, it might be simpler to read and to propagate what Aristotle wrote with such immortal justness and masterly brevity. But times change; and though the principles of reason remain the same the facts of human life and of human conscience alter. A new background, a new basis of application, appears for logic, and it may be useful to restate old truths in new words, the better to prove their eternal validity. Aristotle is, in his morals, Greek, concise, and elementary. As a Greek, he mixes with the ideal argument illustrations, appreciations, and conceptions which are not inseparable from its essence. In themselves, no doubt, these accessories are better than what in modern times would be substituted for them, being less sophisticated and of a nobler stamp; but to our eyes they disguise what is profound and universal in natural morality by embodying it in images which do not belong to our life. Our direst struggles and the last sanctions of our morality do not appear in them. The pagan world, because its maturity was simpler than our crudeness, seems childish to us. We do not find there our sins and holiness, our love, charity, and honour. The Greek too would not find in our world the things he valued most, things to which he surrendered himself, perhaps, with a more constant self-sacrifice—piety, country, friendship, and beauty; and he might add that his ideals were rational and he could attain them, while ours are extravagant and have been missed. Yet even if we acknowledged his greater good fortune, it would be impossible for us to go back and become like him. To make the attempt would show no sense of reality and little sense of humour. We must dress in our own clothes, if we do not wish to substitute a masquerade for practical existence. What we can adopt from Greek morals is only the abstract principle of their development; their foundation in all the extant forces of human nature and their effort toward establishing a perfect harmony among them. These forces themselves have perceptibly changed, at least in their relative power. Thus we are more conscious of wounds to stanch and wrongs to fight against, and less of goods to attain. The movement of conscience has veered; the centre of gravity lies in another part of the character.
