In the first we may easily trace the intellectual expression of the high spirit of self-sacrifice which the patriotic enthusiasm had elicited. The spirit of patriotism has this peculiar characteristic, that, while it has evoked acts of heroism which are both very numerous and very sublime, it has done so without presenting any prospect of personal immortality as a reward. Of all the forms of human heroism, it is probably the most unselfish. The Spartan and the Roman died for his country because he loved it. The martyr's ecstasy of hope had no place in his dying hour. He gave up all he had, he closed his eyes, as he believed, for ever, and he asked for no reward in this world or in the next. Even the hope of posthumous fame—the most refined and supersensual of all that can be called reward—could exist only for the most conspicuous leaders. It was examples of this nature that formed the culminations or ideals of ancient systems of virtue, and they naturally led men to draw a very clear and deep distinction between the notions of interest and of duty. It may, indeed, be truly said, that while the conception of what constituted duty was often very imperfect in antiquity, the conviction that duty, as distinguished from every modification of selfishness, should be the supreme motive of life was more clearly enforced among the Stoics than in any later society.
The reader will probably have gathered from the last chapter that there are four distinct motives which moral teachers may propose for the purpose of leading men to virtue. They may argue that the disposition of events is such that prosperity will attend a virtuous life, and adversity a vicious one—a proposition they may prove by pointing to the normal course of affairs, and by asserting the existence of a special Providence in behalf of the good in the present world, and of rewards and punishments in the future. As far as these latter arguments are concerned, the efficacy of such teaching rests upon the firmness with which certain theological tenets are held, while the force of the first considerations will depend upon the degree and manner in which society is organised, for there are undoubtedly some conditions of society in which a perfectly upright life has not even a general tendency to prosperity. The peculiar circumstances and dispositions of individuals will also influence largely the way in which they receive such teaching, and, as Cicero observed, “what one utility has created, another will often destroy.”
They may argue, again, that vice is to the mind what disease is to the body, and that a state of virtue is in consequence a state of health. Just as bodily health is desired for its own sake, as being the absence of a painful, or at least displeasing state, so a well-ordered and virtuous mind may be valued for its own sake, and independently of all the external good to which it may lead, as being a condition of happiness; and a mind distracted by passion and vice may be avoided, not so much because it is an obstacle in the pursuit of prosperity, as because it is in itself essentially painful and disturbing. This conception of virtue and vice as states of health or sickness, the one being in itself a good and the other in itself an evil, was a fundamental proposition in the ethics of Plato.199 It was admitted, but only to a subsidiary place, by the Stoics,200 and has passed more or less into all the succeeding systems. It is especially favourable to large and elevating conceptions of self-culture, for it leads men to dwell much less upon isolated acts of virtue or vice than upon the habitual condition of mind from which they spring.
It is possible, in the third place, to argue in favour of virtue by offering as a motive that sense of pleasure which follows the deliberate performance of a virtuous act. This emotion is a distinct and isolated gratification following a distinct action, and may therefore be easily separated from that habitual placidity of temper which results from the extinction of vicious and perturbing impulses. It is this theory which is implied in the common exhortations to enjoy 'the luxury of doing good,' and though especially strong in acts of benevolence, in which case sympathy with the happiness created intensifies the feeling, this pleasure attends every kind of virtue.
These three motives of action have all this common characteristic, that they point as their ultimate end to the happiness of the agent. The first seeks that happiness in external circumstances; the second and third in psychological conditions. There is, however, a fourth kind of motive which may be urged, and which is the peculiar characteristic of the intuitive school of moralists and the stumbling-block of its opponents. It is asserted that we are so constituted that the notion of duty furnishes in itself a natural motive of action of the highest order, wholly distinct from all the refinements and modifications of self-interest. The coactive force of this motive is altogether independent of surrounding circumstances, and of all forms of belief. It is equally true for the man who believes and for the man who rejects the Christian faith, for the believer in a future world and for the believer in the mortality of the soul. It is not a question of happiness or unhappiness, of reward or punishment, but of a generically different nature. Men feel that a certain course of life is the natural end of their being, and they feel bound, even at the expense of happiness, to pursue it. They feel that certain acts are essentially good and noble, and others essentially base and vile, and this perception leads them to pursue the one and to avoid the other, irrespective of all considerations of enjoyment.
I have recurred to these distinctions, which were more fully discussed in the last chapter, because the school of philosophy we are reviewing furnishes the most perfect of all historical examples of the power which the higher of these motives can exercise over the mind. The coarser forms of self-interest were in stoicism absolutely condemned. It was one of the first principles of these philosophers that all things that are not in our power should be esteemed indifferent; that the object of all mental discipline should be to withdraw the mind from all the gifts of fortune, and that prudence must in consequence be altogether excluded from the motives of virtue. To enforce these principles they continually dilated upon the vanity of human things, and upon the majesty of the independent mind, and they indulged, though scarcely more than other sects, in many exaggerations about the impassive tranquillity of the sage.201 In the Roman empire stoicism flourished at a period which, beyond almost any other, seemed unfavourable to such teaching. There were reigns when, in the emphatic words of Tacitus, “virtue was a sentence of death.” In no period had brute force more completely triumphed, in none was the thirst for material advantages more intense, in very few was vice more ostentatiously glorified. Yet in the midst of all these circumstances the Stoics taught a philosophy which was not a compromise, or an attempt to moderate the popular excesses, but which was rather in its austere sanctity the extreme antithesis of all that the prevailing examples and their own interests could dictate. And these men were no impassioned fanatics, fired with the prospect of coming glory. They were men from whose motives of action the belief in the immortality of the soul was resolutely excluded. In the scepticism that accompanied the first introduction of philosophy into Rome, in the dissolution of the old fables about Tartarus and the Styx, and the dissemination of Epicureanism among the people, this doctrine had sunk very low, notwithstanding the beautiful reasonings of Cicero and the religious faith of a few who clung like Plutarch to the mysteries in which it was perpetuated. An interlocutor in Cicero expressed what was probably a common feeling when he acknowledged that, with the writings of Plato before him, he could believe and realise it; but when he closed the book, the reasonings seemed to lose their power, and the world of spirits grew pale and unreal.202 If Ennius could elicit the plaudits of a theatre when he proclaimed that the gods took no part in human affairs, Cæsar could assert in the senate, without scandal and almost without dissent, that death was the end of all things.203 Pliny, perhaps the greatest of Roman scholars, adopting the sentiment of all the school of Epicurus, describes the belief in a future life as a form of madness, a puerile and a pernicious illusion.204 The opinions of the Stoics were wavering and uncertain. Their first doctrine was that the soul of man has a future and independent, but not an eternal existence, that it survives until the last conflagration which was to destroy the world, and absorb all finite things into the all-pervading soul of nature. Chrysippus, however, restricted to the best and noblest souls this future existence, which Cleanthes had awarded to all,205 and among the Roman Stoics even this was greatly doubted. The belief that the human soul is a detached fragment of the Deity naturally led to the belief that after death it would be reabsorbed into the parent Spirit. The doctrine that there is no real good but virtue deprived
