But, if this be so, it follows that Mr. Edwin Wallace’s appeal to Aristotle as an authority worth consulting on our present social difficulties cannot be upheld. Take the question quoted by Mr. Wallace himself: ‘Whether the State is a mere combination for the preservation of goods and property, or a moral organism developing the idea of right?’ Aristotle certainly held very strong opinions in favour of State interference with education and private morality, if that is what the second alternative implies; but does it follow that he would agree with those who advocate a similar supervision at the present day? By no means; because experience has shown that in enormous industrial societies like ours, protection is attended with difficulties and dangers which he could no more foresee than he could foresee the discoveries on which our physical science is based. Or, returning for a moment to ethics, let us take another of Mr. Wallace’s problems: ‘Whether intellectual also involves moral progress?’ What possible light can be thrown on it by Aristotle’s exposure of the powerlessness of right knowledge to make an individual virtuous, when writers like Buckle have transferred the whole question from a particular to a general ground; from the conduct of individuals to the conduct of men acting in large masses, and over vast periods of time? Or, finally, take the question which forms a point of junction between Aristotle’s ethics and his politics: ‘Whether the highest life is a life of thought or a life of action?’ Of what importance is his decision to us, who attend far more to the social than to the individual consequences of actions; who have learned to take into account the emotional element of happiness, which Aristotle neglected; who are uninfluenced by his appeal to the blissful theorising of gods in whom we do not believe; for whom, finally, experience has altogether broken down the antithesis between knowledge and practice, by showing that speculative ideas may revolutionise the whole of life? Aristotle is an interesting historical study; but we are as far beyond him in social as in physical science. IV.
