THREE:"Goodnight, comrades," said Lalage. "I shall return presently. Come on, dog, follow at the heels of your master."The radical selfishness of Epicureanism comes out still more distinctly in its attitude towards political activity. Not only does it systematically discourage mere personal ambition73��the desire of possessing political power for the furtherance of one��s own ends��but it passes a like condemnation on disinterested efforts to improve the condition of the people by legislation; while the general rule laid down for the wise man in his capacity of citizen is passive obedience to the established authorities, to be departed from only when the exigencies of self-defence require it. On this Mr. Wallace observes that ��political life, which in all ages has been impossible for those who had not wealth, and who were unwilling to mix themselves with vile and impure associates, was not to the mind of Epicurus.��148 No authority is quoted to prove that the abstention recommended by Epicurus was dictated by purist sentiments of any kind; nor can we readily admit that it is impossible to record a vote, to canvass at an election, or even to address a public meeting, without fulfilling one or other of the conditions specified by Mr. Wallace; and we know by the example of Littr�� that it is possible for a poor man to take a rather prominent part in public life, without the slightest sacrifice of personal dignity.149 It must also be remembered that Epicurus was not speaking for himself alone; he was giving practical advice to all whom it might concern��advice of which he thought, aeque pauperibus prodest, locupletibus aeque; so that when Mr. Wallace adds that, ��above all, it is not the business of a philosopher to become a political partisan, and spend his life in an atmosphere of avaricious and malignant passions,��150 we must observe that Epicureanism was not designed to make philosophers, but perfect men. The real question is whether it would serve the public interest were all who endeavour to shape their lives by the precepts of philosophy to withdraw themselves74 entirely from participation in the affairs of their country. And, having regard to the general character of the system now under consideration, we may not uncharitably surmise that the motive for abstention which it supplied was selfish love of ease far more than unwillingness to be mixed up with the dirty work of politics.

THREE:"I have not ��20 of ready money in the world."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.

THREE:The safety, simplicity, and reliable action of hydraulic machinery has already led to its extensive employment for moving and lifting weights, and it is fair to assume that the importance and success of this invention fully entitle it to be classed as one of the most important that has been made in mechanical engineering during fifty years past. The application of hydraulic force in operating the machinery used in the processes for steel Bessemer manufacture, is one of the best examples to illustrate the advantages and principles of the hydraulic system. Published drawings and descriptions of Bessemer steel plant explain this hydraulic machinery.

THREE:CHAPTER XXVIII. TEMPERING STEEL.Cutting, as a process in converting material, includes the force to propel cutting edges, means to guide and control their action, and mechanism to sustain and adjust the material acted upon. In cutting with hand tools, the operator performs the two functions of propelling and guiding the tools with his hands; but in what [58] is called power operations, machines are made to perform these functions. In nearly all processes machines have supplanted hand labour, and it may be noticed in the history and development of machine tools that much has been lost in too closely imitating hand operations when machines were first applied. To be profitable, machines must either employ more force, guide tools with more accuracy, or move them at greater speed, than is attainable by hand. Increased speed may, although more seldom, be an object in the employment of machinery, as well as the guidance of implements or increased force in propelling them. The hands of workmen are not only limited as to the power that may be exerted, and unable to guide tools with accuracy, but are also limited to a slow rate of movement, so that machines can be employed with great advantage in many operations where neither the force nor guidance of tools are wanting.
