      In making up the time charged to different machines during their construction, a good plan is to supply each workman with a slate and pencil, on which he can enter his time as so many hours or fractions of hours charged to the respective symbols. Instead of interfering with his time, this will increase a workman's interest in what he is doing, and naturally lead to a desire to diminish the time charged to the various symbols. This system leads to emulation among workmen where any operation is repeated by different persons, and creates an interest in classification which workmen will willingly assist in.

      174At the time when Carneades delivered his lectures, the morality of Rome resembled that of Sparta during her great conflict with Athens, as characterised by one of the speakers in the Melian Dialogue. Scrupulously honourable in their dealings with one another, in their dealings with foreign nations her citizens notoriously identified justice with what was agreeable or advantageous to themselves. The arguments of the Academic philosopher must, therefore, have been doubly annoying to the leaders of the State, as a satire on its public policy and as a source of danger to the integrity of its private life. In this respect, old Cato was a type of the whole race. In all transactions with his fellow-citizens, and in every office undertaken on behalf of the community, his honesty was such that it became proverbial. But his absolute disregard of international justice has become equally proverbial through the famous advice, reiterated on every possible occasion, that an unoffending and unwarlike city should be destroyed, lest its existence should at some future time become a source of uneasiness to the mistress of the world. Perhaps it was a secret consciousness of his own inconsistency which prevented him from directly proposing that Carneades should not be allowed to continue his lectures. At any rate, the ex-Censor contented himself with moving that the business on which the Athenian envoys had come should be at once concluded, that they might return to their classes at Athens, leaving the youth of Rome to seek instruction as before from the wise conversation and example of her public men.214 We are not told whether his speech on this occasion wound up with the usual formula, caeterum, Patres Conscripti, sententia mea est Carthaginem esse delendam; but as it is stated that from the year 175 to the end of his life, he never made a motion in the Senate that was not terminated by those words, we are entitled to assume that he did not omit them in the present instance. If so, the effect must have been singularly grotesque; although, perhaps, less so than if attention had been drawn to the customary phrase by its unexpected absence. At any rate, Carneades had an opportunity of carrying back one more illustration of ethical inconsistency wherewith to enliven his lectures on the vanity of dogmatising and the absolute equilibrium of contradictory opinions.

      Other reasons for the extended and general use of steam as a power, besides those already named, are to be found in the fact that no other available element or substance can be expanded to a given degree at so small a cost as water; and that its temperature will not rise to a point injurious to machinery, and, further, in the very important property of lubrication which steam possesses, protecting the frictional surfaces of pistons and valves, which it is impossible to keep oiled because of their inaccessibility or temperature.Quickly he lowered the rope till the bulge of it showed that the bottom was reached. He wound up the rope again, and as he did so a grunt of satisfaction escaped him. It was far better than he had expected.



      "But you agree," said Gregg, unperturbed, "that it might be possible in the future?"Such are the closing words of what was possibly Aristotles last work, the clear confession of his monotheistic creed. A monotheistic creed, we have said, but one so unlike all other religions, that its nature has been continually misunderstood. While some have found in it a theology like that of the Jews or of Plato or of modern Europe, others have resolved it into a vague pantheism. Among the latter we are surprised to find Sir A. Grant, a writer to whom the Aristotelian texts must be perfectly familiar both in spirit and in letter. Yet nothing can possibly be more clear and emphatic than the declarations they contain. Pantheism identifies God with the world; Aristotle separates them as pure form from form more or less alloyed with matter. Pantheism denies personality to God; Aristotle gives him unity, spirituality, self-consciousness, and happiness. If these qualities do not collectively involve personality, we should like to know what does. Need we351 remind the accomplished editor of the Nicomachean Ethics how great a place is given in that work to human self-consciousness, to waking active thought as distinguished from mere slumbering faculties or unrealised possibilities of action? And what Aristotle regarded as essential to human perfection, he would regard as still more essential to divine perfection. Finally, the God of pantheism is a general idea; the God of Aristotle is an individual. Sir A. Grant says that he (or it) is the idea of Good.247 We doubt very much whether there is a single passage in the Metaphysics to sanction such an expression. Did it occur, however, that would be no warrant for approximating the Aristotelian to the Platonic theology, in presence of such a distinct declaration as that the First Mover is both conceptually and numerically one,248 coming after repeated repudiations of the Platonic attempt to isolate ideas from the particulars in which they are immersed. Then Sir A. Grant goes on to speak of the desire felt by Nature for God as being itself God,249 and therefore involving a belief in pantheism. Such a notion is not generally called pantheism, but hylozoism, the attribution of life to matter. We have no desire, however, to quarrel about words. The philosopher who believes in the existence of a vague consciousness, a spiritual effort towards something higher diffused through nature, may, if you will, be called a pantheist, but not unless this be the only divinity he recognises. The term is altogether misleading when applied to one who also proclaims the existence of something in his opinion far higher, better and more reala living God, who transcends Nature, and is independent of her, although she is not independent of him.

      Reaction wheels are employed to a limited extent only, and will soon, no doubt, be extinct as a class of water-wheels. In speaking of reaction wheels, I will select what is called Barker's mill for an example, because of the familiarity with which it is known, although its construction is greatly at variance with modern reaction wheels.CHAPTER I
