FORE:A few years ago, or even at the present time, many school-books in use which treat of mechanics in connection with natural philosophy are so arranged as to hinder a learner from grasping a true conception of force, power, and motion; these elements were confounded with various agents of transmission, such as wheels, wedges, levers, screws, and so on. A learner was taught to call these things "mechanical powers," whatever that may mean, and to compute their power as mechanical elements. In this manner was fixed in the mind, as many can bear witness, an erroneous conception of the relations between power and the means for its transmission; the two things were confounded together, so that years, and often a lifetime, has not served to get rid of the idea of power and mechanism being the same. To such teaching can be traced nearly all the crude ideas of mechanics so often met with among those well informed in other matters. In the great change from empirical rules to proved constants, from special and experimental knowledge to the application of science [4] in the mechanic arts, we may, however, go too far. The incentives to substitute general for special knowledge are so many, that it may lead us to forget or underrate that part which cannot come within general rules."Go on," said Leona. "Nothing seems to be concealed from you. Now please tell me what happens next."

FORE:The analogy between steam-power and water-power is therefore quite complete. Water is in both cases the medium through which power is obtained; evaporation is also the leading principle in both, the main difference being that in the case of steam-power the force employed is directly from the expansion of water by heat, and in water-power the force is an indirect result of expansion of water by heat.The third great idea of Stoicism was its doctrine of humanity. Men are all children of one Father, and citizens37 of one State; the highest moral law is, Follow Nature, and Nature has made them to be social and to love one another; the private interest of each is, or should be, identified with the universal interest; we should live for others that we may live for ourselves; even to our enemies we should show love and not anger; the unnaturalness of passion is proved by nothing more clearly than by its anti-social and destructive tendencies. Here, also, the three great Stoics of the Roman empireSeneca, Epicttus, and Marcus Aureliusrather than the founders of the school, must be our authorities;82 whether it be because their lessons correspond to a more developed state of thought, or simply because they have been more perfectly preserved. The former explanation is, perhaps, the more generally accepted. There seems, however, good reason for believing that the idea of universal lovethe highest of all philosophical ideas next to that of the universe itselfdates further back than is commonly supposed. It can hardly be due to Seneca, who had evidently far more capacity for popularising and applying the thoughts of others than for original speculation, and who on this subject expresses himself with a rhetorical fluency not usually characterising the exposition of new discoveries. The same remark applies to his illustrious successors, who, while agreeing with him in tone, do not seem to have drawn on his writings for their philosophy. It is also clear that the idea in question springs from two essentially Stoic conceptions: the objective conception of a unified world, a cosmos to which all men belong;38 and the subjective conception of a rational nature common to them all. These, again, are rooted in early Greek thought, and were already emerging into distinctness at the time of Socrates. Accordingly we find that Plato, having to compose a characteristic speech for the Sophist Hippias, makes him say that like-minded men are by nature kinsmen and friends to one another.83 Nature, however, soon came to be viewed under a different aspect, and it was maintained, just as by some living philosophers, that her true law is the universal oppression of the weak by the strong. Then the idea of mind came in as a salutary corrective. It had supplied a basis for the ethics of Protagoras, and still more for the ethics of Socrates; it was now combined with its old rival by the Stoics, and from their union arose the conception of human nature as something allied with and illustrated by all other forms of animal life, yet capable, if fully developed, of rising infinitely above them. Nevertheless, the individual and the universal element were never quite reconciled in the Stoic ethics. The altruistic quality of justice was clearly perceived; but no attempt was made to show that all virtue is essentially social, and has come to be recognised as obligatory on the individual mainly because it conduces to the safety of the whole community. The learner was told to conquer his passions for his own sake rather than for the sake of others; and indulgence in violent anger, though more energetically denounced, was, in theory, placed on a par with immoderate delight or uncontrollable distress. So also, vices of impurity were classed with comparatively harmless forms of sensuality, and considered in reference, not to the social degradation of their victims, but to the spiritual defilement of their perpetrators.

THREE:These remarks upon hammers are not introduced here as a matter of curiosity, nor with any intention of following mechanical principles beyond where they will explain actual manipulation, but as a means of directing attention to percussive acting machines generally, with which forging processes, as before explained, have an intimate connection.Thus, so far as was possible in such altered circumstances, did the Renaissance of the second century reproduce the271 intellectual environment from which Platos philosophy had sprung. In literature, there was the same attention to words rather than to things; sometimes taking the form of exact scholarship, after the manner of Prodicus; sometimes of loose and superficial declamation, after the manner of Gorgias. There was the naturalism of Hippias, elaborated into a system by the Stoics, and practised as a life by the new Cynics. There was the hedonism of Aristippus, inculcated under a diluted form by the Epicureans. There was the old Ionian materialism, professed by Stoics and Epicureans alike. There was the scepticism of Protagoras, revived by Aenesidmus and his followers. There was the mathematical mysticism of the Pythagoreans, flourishing in Egypt instead of in southern Italy. There was the purer geometry of the Alexandrian Museum, corresponding to the school of Cyrn. On all sides, there was a mass of vague moral preaching, without any attempt to exhibit the moral truths which we empirically know as part of a comprehensive metaphysical philosophy. And, lastly, there was an immense undefined religious movement, ranging from theologies which taught the spirituality of God and of the human soul, down to the most irrational and abject superstition. We saw in the last chapter how, corresponding to this environment, there was a revived Platonism, that Platonism was in fact the fashionable philosophy of that age, just as it afterwards became the fashionable philosophy of another Renaissance thirteen centuries later. But it was a Platonism with the backbone of the system taken out. Platos thoughts all centred in a carefully considered scheme for the moral and political regeneration of society. Now, with the destruction of Greek independence, and the absorption everywhere of free city-states into a vast military empire, it might seem as if the realisation of such a scheme had become altogether impracticable. The Republic was, indeed, at that moment realising itself under a form adapted to the altered exigencies of the time; but no Platonist could as yet recognise272 in the Christian Church even an approximate fulfilment of his masters dream. Failing any practical issue, there remained the speculative side of Platos teaching. His writings did not embody a complete system, but they offered the materials whence a system could be framed. Here the choice lay between two possible lines of construction; and each had, in fact, been already attempted by his own immediate disciples. One was the Pythagorean method of the Old Academy, what Aristotle contemptuously called the conversion of philosophy into mathematics. We saw in the last chapter how the revived Platonism of the first and second centuries entered once more on the same perilous path, a path which led farther and farther away from the true principles of Greek thought, and of Plato himself when his intellect stood at its highest point of splendour. Neo-Pythagorean mysticism meant an unreconciled dualism of spirit and matter; and as the ultimate consequence of that dualism, it meant the substitution of magical incantations and ceremonial observances for the study of reason and virtue. Moreover, it readily allied itself with Oriental beliefs, which meant a negation of natural law that the Greeks could hardly tolerate, and, under the form of Gnostic pessimism, a belief in the inherent depravity of Nature that they could not tolerate at all.
