Utilitarianism agrees with the ancient hedonism in holding pleasure to be the sole good and pain the sole evil. Its adherents also, for the most part, admit that the desire of the one and the dread of the other are the sole motives to action; but, while making the end absolutely universal and impersonal, they make the motive into a momentary impulse, without any necessary relation to the future happiness of the agent himself. The good man does his duty because doing it gives him pleasure, or because the failure to do it would give him pain, at the moment; although he knows that a contrary course would save him from greater pain or win him greater pleasure hereafter. No accurate thinker would call this acting from a selfish or interested motive; nor does it agree with the teaching of Epicurus. Were all sensitive beings to be united in a single organism, then, on utilitarian principles, self-interest, interpreted in the sense of seeking its own preservation and pleasure, would be the only law that the individualised aggregate could rationally obey. But the good of each part would be rigorously subordinated to the good of the whole; and utilitarian morality desires that we should act as if this hypothesis were realised, at least in reference to our own particular interests. Now, the idea of humanity as forming such a consolidated whole is not Epicurean. It belongs to the philosophy which always reprobated pleasure, precisely because its pursuit is associated with the dereliction of public duty and with bitter rivalry for the possession of what, by its very nature, exists only in limited quantities, while the demand for it is unlimited or, at any rate, far exceeds the supply. According to the Stoics, there was only one way in which the individual could study his private interest without abandoning his position as a social being, and this was to find it exclusively in the practice of virtue.[575] But virtue and public interest remained mere forms scantily supplemented by appeals to the traditional morality, until the idea of generalised happiness, of pleasure diffused through the whole community, came to fill them with substance and life.

It has also to be observed that the idea of utility as a test of moral goodness is quite distinct from hedonism. Plato proclaims, in the most unequivocal terms, that actions must be estimated by their consequences instead of by the feelings of sympathy or antipathy which they excite; yet no one could object more strongly to making pleasure the end of action. Thus, three distinct doctrines seem to converge in modern English ethics, of which all are traceable to Greek philosophy, but only one to Epicureanism in particular, and not ultimately to that but to the older systems whence it sprang.

And here we unexpectedly find ourselves confronted by a new relation between ancient and modern thought. Each acts as a powerful precipitant on the other, dissolving what might otherwise have passed for inseparable associations, and combining elements which a less complete experience might have led us to regard as necessarily incompatible with one another. The instance just analysed is highly significant; nor does it stand alone. Modern spiritualists often talk as if morality was impossible apart from their peculiar metaphysics. But the Stoics, confessedly the purest moralists of antiquity, were uncompromising materialists; while the spiritualist Aristotle taught what is not easily distinguishable from a very refined sort of egoism. Again, the doctrine of free-will is now commonly connected with a belief in the separability of consciousness from matter, and, like that, is declared to be an indispensable condition of morality. Among the Greeks, however, it was held by the materialist Epicureans more distinctly than by any other school; while the Stoics did not find necessarianism inconsistent with self-sacrificing virtue. The partial derivation of knowledge from an activity in our own minds is another supposed concomitant of spiritualism; although Aristotle traces every idea to an external source, while at the same time holding some cognitions to be necessarily true—a theory repudiated by modern experientialists. To Plato, the spirituality of the soul seemed to involve its pre-existence no less than its immortality, a consequence not accepted by his modern imitators. Teleology is now commonly opposed to pantheism; the two were closely combined in Stoicism; while Aristotle, although he believed in a personal God, attributed the marks of design in Nature to purely unconscious agencies.

IX.

The naturalism and utilitarianism of the eighteenth century are the last conceptions directly inherited from ancient philosophy by modern thought. Henceforward, whatever light the study of the former can throw on the vicissitudes of the latter is due either to their partial parallelism, or to an influence becoming every day fainter and more difficult to trace amid the multitude of factors involved. The progress of analytical criticism was continually deflected or arrested by the still powerful resistance of scholasticism, just as the sceptical tendencies of the New Academy had been before, though happily with less permanent success; and as, in antiquity, this had happened within no less than without the critical school, so also do we find Locke clinging to the theology of Descartes; Berkeley lapsing into Platonism; Hume playing fast and loose with his own principles; and Kant leaving it doubtful to which side he belongs, so evenly are the two opposing tendencies balanced in his mind, so dexterously does he adapt the new criticism to the framework of scholastic logic and metaphysics.

Meanwhile the strength of the analytical method was doubled by its extension to the phenomena of growth and change; for, as applied to these, it became the famous theory of Development or Evolution. No idea belongs so completely to modern philosophy; for even the ancient thinkers who threw their cosmology into a historical form had never attempted to explain the present by the past. If anything, they explained the past by the present, assuming a rough analogy to exist between the formation of the universe as a whole and the genesis of those natural or artificial bodies which were continually growing or being built up before their eyes. Their cosmology was, in fact, nothing but the old mythology stripped of its personal or conscious element; and, like it, was a hypothesis unsupported by any external evidence;—a criticism not inconsistent with the admission that to eliminate the supernatural element from speculation was, even in the absence of any solid addition to human knowledge, an achievement of inestimable value. The evolutionary method is also an elimination of the supernatural, but it is a great deal more. By tracing the history of compound structures to their first origin, and noting the successive increments to which their gradual growth is due, it reveals, as no statical analysis ever could, the actual order of synthesis, and the meaning of the separate constituents by whose joint action their movements are determined; while, conversely, their dissolution supplies us with a number of ready-made experiments in which the influence of each particular factor in the sum total may be detected by watching the changes that ensue on its removal. In a word, the method of evolution is the atomistic method, extended from matter to motion, and viewed under the form of succession instead of under the form of co-existence.

As a universal philosophy, the theory of Development, like every other modern idea, has only been permitted to manifest itself in combination with different forms of the old scholasticism. The whole speculative movement of our century is made up of such hybrid systems; and three, in particular, still divide the suffrages of many thinking men who have not been able entirely to shake off the influence of reactionary ideas. These are the systems of Hegel, of Comte, and of Mr. Herbert Spencer. In each, the logic and metaphysics inherited from Greek thought are variously compounded with the new science. And each, for that very reason, serves to facilitate the transition from one to the other; a part analogous to that played among the Greeks themselves by the vast constructions of Plato and Aristotle, or, in an age of less productivity, by the Stoic and Alexandrian philosophies.

The influence of Aristotle has, indeed, continued to make itself felt not only through the teaching of his modern imitators, but more directly as a living tradition in literature, or through the renewed study of his writings at first hand. Even in the pure sciences, it survived until a comparatively recent period, and, so far as the French intellect goes, it is not yet entirely extinct. From Abélard on, Paris was the headquarters of that soberer scholasticism which took its cue from the Peripatetic logic; and the resulting direction of thought, deeply impressed as it became on the French character and the French language, was interrupted rather than permanently altered by the Cartesian revolution, and, with the fall of Cartesianism, gradually recovered its old predominance. The Aristotelian philosophy is remarkable above all others for clear definitions, full descriptions, comprehensive classifications, lucid reasoning, encyclopaedic science, and disinterested love of knowledge; along with a certain incapacity for ethical speculation,[576] strong conservative leanings, and a general tendency towards the rigid demarcation rather than the fruitful commingling of ideas. And it will probably be admitted that these are also traits characteristic of French thinking as opposed to English or German thinking. For instance, widely different as is the Mécanique Céleste from the astronomy of Aristotle’s treatise On the Heavens, both agree in being attempts to prove the eternal stability of the celestial system.[577] The destructive deluges by which Aristotle supposes civilisation to be periodically interrupted, reappear on a larger scale in the theory of catastrophes still held by French geologists. Another Aristotelian dogma, the fixity of organic species, though vigorously assailed by eminent French naturalists, has, on the whole, triumphed over the opposite doctrine of transformism in France, and now impedes the acceptance of Darwin’s teaching even in circles where theological prepossessions are extinct. The accepted classifications in botany and zoology are the work of Frenchmen following in the footsteps of Aristotle, whose genius for methodical arrangement was signally exemplified in at least one of these departments; the division of animals into vertebrate and invertebrate being originally due to him. Bichat’s distinction between the animal and the vegetable functions recalls Aristotle’s distinction between the sensitive and nutritive souls; while his method of studying the tissues before the organs is prefigured in the treatise on the Parts of Animals. For a long time, the ruling of Aristotle’s Poetics was undisputed in French criticism; and if anything could disentitle Montesquieu’s Esprit des Lois to the proud motto, Prolem sine matre creatam, it would be its close relationship to the Politics of the same universal master. Finally, if it be granted that the enthusiasm for knowledge, irrespective of its utilitarian applications, exists to a greater degree among the educated classes of France than in any other modern society, we may plausibly attribute this honourable characteristic to the fostering influence of one who has proclaimed more eloquently than any other philosopher that theoretical activity is the highest good of human life, the ideal of all Nature, and the sole beatitude of God.

It remains to add a few words on the position which ancient and modern philosophy respectively occupy towards theology. Here their relation is one of contrast rather than of resemblance. The Greek thinkers start at an immense distance from religious belief, and their first allusions to it are marked by a scornful denial of its validity. Gradually, with the transition from physical to ethical enquiries, an approximation between the two is brought about, though not without occasional returns to their former attitude of hostility. Finally, in presence of a common danger they become interwoven and almost identified with one another; while the new religion against which they make common cause, itself presents the same spectacle of metaphysical and moral ideas entering into combination with the spontaneous products of popular mythology. And be it observed that throughout the whole of this process action and reaction were equal and contrary. The decline and corruption of philosophy was the price paid for the elevation and purification of religion. While the one was constantly sinking, the other was constantly rising, until they converged on the plane of dogmatic theology. By the very circumstances of the case, an opposite course has been imposed on the development of modern philosophy. Starting from an intimate union with religion, it slowly disengages itself from the compromising alliance; and, although, here also, the normal course of ideas has been interrupted by frequent reactions, the general movement of European thought has been no less decidedly towards a complete emancipation from the popular beliefs than the movement of Greek thought had been towards their conciliation and support.
