<000005>This method of treating the subject of motive-engines will no doubt be presenting it in a new way, but it is merely beginning at an unusual place. A learner who commences with first principles, instead of pistons, valves, connections, and bearings, will find in the end that he has not only adopted the best course, but the shortest one to understand steam and other expansive engines.
The next and perhaps the most important point in favour of Epicureanism is its theory of pleasure as the end of action. Plato had left his idea of the good undefined; Aristotle had defined his in such a manner as to shut out the vast majority of mankind from its pursuit; the Stoics had revolted every instinct by altogether discarding pleasure as an end, and putting a purely formal and hollow perfection in its place. It must further be admitted that Epicurus, in tracing back justice to the two ideas of interest and contract, had hold of a true and fertile principle. Nevertheless, although ethics is his strongest ground, his usual ill-luck pursues him even here. It is where he is most original that he goes most astray. By reducing pleasure, as an end of action, to the mere removal of pain, he alters earlier systems of hedonism for the worse; and plays the game of pessimism by making it appear that, on the whole, death must be preferable to life, since it is what life can never bea state of absolute repose. And by making self-interest, in the sense of seeking nothing but ones own pleasure or the means to it, the only rule of action, he endangers the very foundations of society. At best, the selfish system, as Coleridge has beautifully observed, stands in a similar relation to the law of conscience or universal selfless reason, as the dial to the sun which indicates its path by intercepting its radiance.210 Nor is the indication so certain as Coleridge admitted. A time may come when116 self-sacrifice shall be unnecessary for the public welfare, but we are not within a measurable distance of it as yet.
FORE:On passing from Seneca to Epicttus, we find that the religious element has received a considerable accession of strength, so considerable, indeed, that the simple progress of time will not altogether account for it. Something is due to the superior devoutness of the Eastern mindEpicttus was a Phrygian,and still more to the difference in station between the two philosophers. As a noble, Seneca belonged to the class which was naturally most inclined to adopt an independent attitude towards the popular beliefs; as a slave, Epicttus belonged to the class which was naturally most amenable to their authority. It was, however, no accident that philosophy should, at a distance of only a generation, be represented by two such widely contrasted individuals; for the whole tendency of Roman civilisation was, as we have seen, to bring the Oriental element and the servile element of society into ever-increasing prominence. Nothing proves the ascendency of religious considerations in the mind of Epicttus more strongly than his aversion from the physical enquiries which were eagerly prosecuted by Seneca. Nature interests him solely as a manifestation of divine wisdom and goodness. As a consequence of this intensified religious feeling, the Stoic theory of natural law is transformed, with Epicttus, into an expression of filial submission to the divine will, while the Stoic teleology becomes an enumeration of the blessings showered by providence on man. In the latter respect, his standpoint approaches very near to that of Socrates, who, although a free-born Athenian citizen, belonged, like him, to the poorer classes, and sympathised deeply with their feeling of dependence on supernatural protection,a remark which also applies to the humble day-labourer244 Cleanthes. Epicttus also shares the idea, characteristic of the Platonic rather than of the Xenophontic Socrates, that the philosopher is entrusted with a mission from God, without which it would be perilous for him to undertake the office of a teacher, and which, in the discharge of that office, he should keep constantly before his eyes. But the dialectical element which with Socrates had furnished so strong a counterpoise to the authoritative and traditional side of his philosophy, is almost entirely wanting in the discourses of his imitator, and the little of it which he admits is valued only as a means of silencing the Sceptics. On the other hand, the weakness and insignificance of human nature, considered on the individual side, are abundantly illustrated, and contemptuous diminutives are habitually used in speaking of its component parts.378 It would seem that the attitude of prostration before an overwhelming external authority prevented Epicttus from looking very favourably on the doctrine of individual immortality; and even if he accepted that doctrine, which seems in the highest degree improbable, it held a much less important place in his thoughts than in those of Cicero and Seneca. It would seem, also, that the Stoic materialism was betraying its fundamental incompatibility with a hope originally borrowed from the idealism of Plato. Nor was this renunciation inconsistent with the ethical dualism which drew a sharp line of distinction between flesh and spirit in the constitution of man, for the superiority of the spirit arose from its identity with the divine substance into which it was destined to be reabsorbed after death.379It is interesting to observe how, here also, the positive science of the age had a large share in determining its philosophic character. Founded on the discovery of the earths true shape, Aristotles metaphysics had been overthrown by the discovery of the earths motion. And now the claims of Cartesianism to have furnished an exact knowledge of matter and a definition of it whence all the facts of observation could be deduced priori, were summarily refuted by the discovery421 of universal gravitation. The Cartesians complained that Newton was bringing back the occult qualities of the Schoolmen; but the tendency of bodies to move towards one another proved as certain as it was inexplicably mysterious. For a time, the study of causes was superseded by the study of laws; and the new method of physical science moved in perfect harmony with the phenomenism of Locke. One most important consequence of this revolution was to place the new Critical philosophy on a footing quite different from that occupied by the ancient sceptics. Both restricted certain knowledge to our own states of consciousness; but it now appeared that this might be done without impeaching the value of accepted scientific conclusions, which was more than the Academic philosophy would have admitted. In other words, granting that we were limited to phenomena, it was shown that science consisted in ascertaining the relations of these phenomena to one another, instead of to a problematic reality lying behind them; while, that such relations existed and were, in fact, part of the phenomena themselves, was what no sceptic could easily deny.
THREE:The last mentioned principle gives one more illustration of the distinction between Aristotles system and that of the evolutionist, properly so called. The continuity recognised329 by the former only obtains among a number of coexisting types; it is a purely logical or ideal arrangement, facilitating the acquisition and retention of knowledge, but adding nothing to its real content. The continuity of the latter implies a causal connexion between successive types evolved from each other by the action of mechanical forces. Moreover, our modern theory, while accounting for whatever is true in Aristotles conception, serves, at the same time, to correct its exaggeration. The totality of existing species only imperfectly fill up the interval between the highest human life and the inorganic matter from which we assume it to be derived, because they are collaterally, and not lineally, related. Probably no one of them corresponds to any less developed stage of another, although some have preserved, with more constancy than others, the features of a common parent. In diverging from a single stock (if we accept the monogenetic hypothesis,) they have become separated by considerable spaces, which the innumerable multitude of extinct species alone could fill up.PREFACE.

"It's about those letters I found in your possession," Prout said, "the letters to you from your brother. I know they are from your brother, because I have seen him, and also his handwriting. You need not be afraid of him, because he is far beyond being injured by any one in the world."The action of steam-hammers may also be divided into what is termed elastic blows, and dead blows."A man in the morning room," gasped Hetty. "A man with a horrid crooked nose and hands all over queer orange spots. Shall I alarm the house----"62We now understand why Protagoras, in the Platonic dialogue bearing his name, should glance scornfully at the89 method of instruction pursued by Hippias, with his lectures on astronomy, and why he prefers to discuss obscure passages in the poets. The quarrel between a classical and a scientific education was just then beginning, and Protagoras, as a Humanist, sided with the classics. Again, he does not think much of the great and sane and noble race of brutes. He would not, like the Cynics, take them as examples of conduct. Man, he says, is naturally worse provided for than any animal; even the divine gift of wisdom would not save him from extinction without the priceless social virtues of justice and reverence, that is, the regard for public opinion which Mr. Darwin, too, has represented as the strongest moralising power in primitive society. And, as the possession of these qualities constituted the fundamental distinction between men and brutes, so also did the advantage of civilisation over barbarism rest on their superior development, a development due to the ethical instruction received by every citizen from his earliest infancy, reinforced through after-life by the sterner correction of legal punishments, and completed by the elimination of all individuals demonstrably unfitted for the social state. Protagoras had no sympathy with those who affect to prefer the simplicity of savages to the fancied corruption of civilisation. Hear how he answers the Rousseaus and Diderots of his time:
