- THREE:"It is as I tell you!"Nevertheless Bacons own attitude towards final causes differs essentially from Descartes. The French mathematician, had he spoken his whole mind, would probably have denied their existence altogether. The English reformer fully admits their reality, as, with his Aristotelian theory of Forms, he could hardly avoid doing; and we find that he actually associates the study of final with that of formal causes, assigning both to metaphysics as its peculiar province. This being so, his comparative neglect of the former is most easily explained by the famous comparison of teleological enquiries to vestal virgins, dedicated to the service of God and bearing no offspring; for Mr. Ellis has made it perfectly clear that the barrenness alluded to is not scientific but industrial. Our knowledge is extended when we trace the workings of a divine purpose in Nature; but this is not a kind of knowledge which bears fruit in useful mechanical inventions.553 Bacon probably felt that men would not be very forward to improve on Nature if they believed in the perfection of her works and in their beneficent adaptation to our wants. The teleological spirit was as strong with him as with Aristotle, but it took a different direction. Instead of studying the adaptation of means to ends where it already existed, he wished men to create it for themselves. But the utilitarian tendency, which predominated with Bacon, was quite exceptional with Descartes. Speaking generally, he desired knowledge for its own sake, not as an instrument for the gratification of other wants; and this intellectual disinterestedness was, perhaps, another aspect of the severance effected between thought and matter. ONE:Nothing animate or inanimate in nature is uniform; plants, trees, animals, are all different; even the air we breathe and the temperature around us is constantly changing; only one thing is constant, that is time, and to this must we go for all our standards.

Most generally the missus wore a good paste imitation.All existence, according to Plotinus, proceeds from the One, which he also calls God. But God does not create the world by a conscious exercise of power; for, as we have seen, every form of consciousness is excluded from his definition.319 Neither does it proceed from him by emanation, for this would imply a diminution of his substance.469 It is produced by an overflow of his infinite power.470 Our philosopher tries to explain and defend this rather unintelligible mode of derivation by the analogy of physical substances and their actions. Light is constantly coming from the sun without any loss to the luminary itself.471 And all things are, in like manner, constantly communicating their proper virtue to others while remaining unaltered themselves. Here we have a good example of the close connexion between science and abstract speculation. People often talk as if metaphysics was something beyond the reach of verification. But some metaphysical theories admit, at any rate, of disproof, in so far as they are founded on false physical theories. Had Plotinus known that neither the sun nor anything else in Nature can produce force out of nothing, he would, very probably, have hesitated to credit the One with such a power. ONE:The Stoic arguments are, indeed, when we come to analyse them, appeal to authority rather than to the logical understanding. We are told again and again that the common objects of desire and dread cannot really be good or evil, because they are not altogether under our control.55 And if we ask why this necessarily excludes them from the class of things to be pursued or avoided, the answer is that man, having been created for perfect happiness, must also have been created with the power to secure it by his own unaided exertions. But, even granting the very doubtful thesis that there is any ascertainable purpose in creation at all, it is hard to see how the Stoics could have answered any one who chose to maintain that man is created for enjoyment; since, judging by experience, he has secured a larger share of it than of virtue, and is just as capable of gaining it by a mere exercise of volition. For the professors of the Porch fully admitted that their ideal sage had never been realised; which, with their opinions about the indivisibility of virtue, was equivalent to saying that there never had been such a thing as a good25 man at all. Or, putting the same paradox into other words, since the two classes of wise and foolish divide humanity between them, and since the former class has only an ideal existence, they were obliged to admit that mankind are not merely most of them fools, but all fools. And this, as Plutarch has pointed out in his very clever attack on Stoicism, is equivalent to saying that the scheme of creation is a complete failure.56Considered upon grounds of commercial expediency as a question of cost alone, it is generally cheaper to move material by hand when it can be easily lifted or moved by workmen, when the movement is mainly in a horizontal direction, and when the labour can be constantly employed; or, to assume a general rule which in practice amounts to much the same thing, vertical lifting should be done by motive power, and horizontal movement for short distances performed by hand. There is nothing more unnatural than for men to carry loads up stairs or ladders; the effort expended in such cases is one-half or more devoted to raising the weight of the body, which is not utilised in the descent, and it is always better to employ winding or other mechanism for raising weights, even when it is to be operated by manual labour. Speaking of this matter of carrying loads upward, I am reminded of the fact that builders in England and America, especially in the latter country, often have material carried up ladders, while in some of the older European countries, where there is but little pretension to scientific manipulation, bricks are usually tossed from one man to another standing on ladders at a distance of ten to fifteen feet apart.

THREE:Civil engineering, in the meaning assumed for the term, has become almost a pure mathematical science. Constants are proved and established for nearly every computation; the strength and durability of materials, from long and repeated tests, has come to be well understood; and as in the case of machine tools, the uniformity of practice among civil engineers, and the perfection of their works, attest how far civil engineering has become a true science, and proves that the principles involved in the construction of permanent works are well understood.An apprentice in entering the workshop should avoid everything tending to an appearance of fastidiousness, either of manner or dress; nothing is more repulsive to workmen, and it may be added, nothing is more out of place in a machine shop than to divide one's time between the work and an attempt to keep clean. An effort to keep as neat as the nature of the work will admit is at all times right, but to dress in clothing not appropriate, or to allow a fear of grease to interfere with the performance of work, is sure to provoke derision.
THREE:How far Plotinus was indebted to Ammonius Saccas for his speculative ideas is another question with respect to which the Pythagoreanising tendencies of his biographer may282 possibly have contributed to the diffusion of a serious misconception. What Porphyry tells us is this. Before leaving Alexandria, Plotinus had bound himself by a mutual agreement with two of his fellow-pupils, Herennius and Origines (not the Christian Father, but a pagan philosopher of the same age and name), to keep secret what they had learned by listening to the lectures of Ammonius. Herennius, however, soon broke the compact, and Origines followed his example. Plotinus then considered that the engagement was at an end, and used the results of his studies under Ammonius as the basis of his conversational lectures in Rome, the substance of which, we are left to suppose, was subsequently embodied in his published writings. But, as Zeller has pointed out, this whole story bears a suspicious resemblance to what is related of the early Pythagorean school. There also the doctrines of the master were regarded by his disciples as a mystery which they pledged themselves to keep secret, and were only divulged through the infidelity of one among their number, Philolaus. And the same critic proves by a careful examination of what are known to have been the opinions of Origines and Longinus, both fellow-pupils of Plotinus, that they differed from him on some points of essential importance to his system. We cannot, therefore, suppose that these points were included in the teaching of their common master, Ammonius.425 But if this be so, it follows that Plotinus was the real founder of the Neo-Platonic school; and, in all cases, his writings remain the great source whence our knowledge of its first principles is derived.
