THREE:We can understand, then, why the philosophy which, when first promulgated, had tended to withdraw its adherents from participation in public life, should, when transplanted to Roman soil, have become associated with an energetic interest in politics; why it was so eagerly embraced by those noble statesmen who fought to the death in defence of their ancient liberties; how it could become the cement of a senatorial opposition under the worst Caesars; how it could be the inspiration and support of Romes Prime Minister during that quinquennium Neronis which was the one bright episode in more than half a century of shame and terror; how, finally, it could mount the throne with Marcus Aurelius, and prove, through his example, that the worlds work might be most faithfully performed by one in whose meditations mere worldly interests occupied the smallest space. Nor can we agree with Zeller in thinking that it was the nationality, and not the philosophy, of these disciples which made them such efficient statesmen.81 On the contrary, it seems to us that the Romanism of these men was inseparable from their philosophy, and that they were all the more Roman because they were Stoics as well.Notwithstanding the radical error of Aristotles philosophythe false abstraction and isolation of the intellectual from the material sphere in Nature and in human lifeit may furnish a useful corrective to the much falser philosophy insinuated, if not inculcated, by some moralists of our own age and country. Taken altogether, the teaching of these writers seems to be that the industry which addresses itself to the satisfaction of our material wants is much more meritorious than the artistic work which gives us direct aesthetic enjoyment, or the literary work which stimulates and gratifies our intellectual cravings; while within the artistic sphere fidelity of portraiture is preferred to the creation of ideal beauty; and within the intellectual sphere, mere observation of facts is set above the theorising power by which facts are unified and explained. Some of the school to whom we allude are great enemies of materialism; but teaching like theirs is materialism of the worst description. Consistently carried400 out, it would first reduce Europe to the level of China, and then reduce the whole human race to the level of bees or beavers. They forget that when we were all comfortably clothed, housed, and fed, our true lives would have only just begun. The choice would then remain between some new refinement of animal appetite and the theorising activity which, according to Aristotle, is the absolute end, every other activity being only a means for its attainment. There is not, indeed, such a fundamental distinction as he supposed, for activities of every order are connected by a continual reciprocity of services; but this only amounts to saying that the highest knowledge is a means to every other end no less than an end in itself. Aristotle is also fully justified in urging the necessity of leisure as a condition of intellectual progress. We may add that it is a leisure which is amply earned, for without it industrial production could not be maintained at its present height. Nor should the same standard of perfection be imposed on spiritual as on material labour. The latter could not be carried on at all unless success, and not failure, were the rule. It is otherwise in the ideal sphere. There the proportions are necessarily reversed. We must be content if out of a thousand guesses and trials one should contribute something to the immortal heritage of truth. Yet we may hope that this will not always be so, that the great discoveries and creations wrought out through the waste of innumerable lives are not only the expiation of all error and suffering in the past, but are also the pledge of a future when such sacrifices shall no longer be required.
