FORE:Machines and tools operating by percussive action, although they comprise a numerous class, and are applied in nearly all mechanical operations, have never received that amount of attention in text-books which the importance of the machines and their extensive use calls for. Such machines have not even been set off as a class and treated of separately, although the distinction is quite clear between machines with percussive action, and those with what may be termed direct action, both in the manner of operating and in the general plans of construction. There is, of course, no lack of formul? for determining the measure of force, and computing the dynamic effect of percussive machines acting against a measured or assumed resistance, and so on; but this is not what is meant. There are certain conditions in the operation of machines, such as the strains which fall upon supporting frames, the effect produced upon malleable material when struck or pressed, and more especially of conditions which may render percussive or positive acting machines applicable to certain purposes; but little explanation has been given which is of value to practical men.

THREE:He was an efficient officer in his way, only, like most members of the force, he lacked imagination. Give him something to work on, and there was not a more efficient detective in New Scotland Yard. But there was no clue here, so he had to fall back on the old familiar methods.The treatment of the passions by the Stoic school presents greater difficulties, due partly to their own vacillation, partly to the very indefinite nature of the feelings in question. It will be admitted that here also the claims of duty are supreme. To follow the promptings of fear or of anger, of pity or of love, without considering the ulterior consequences of our action, is, of course, wrong. For even if, in any particular instance, no harm comes of the concession, we cannot be sure that such will always be the case; and meanwhile the passion is23 strengthened by indulgence. And we have also to consider the bad effect produced on the character of those who, finding themselves the object of passion, learn to address themselves to it instead of to reason. Difficulties arise when we begin to consider how far education should aim at the systematic discouragement of strong emotion. Here the Stoics seem to have taken up a position not very consistent either with their appeals to Nature or with their teleological assumptions. Nothing strikes one as more unnatural than the complete absence of human feeling; and a believer in design might plausibly maintain that every emotion conduced to the preservation either of the individual or of the race. We find, however, that the Stoics, here as elsewhere reversing the Aristotelian method, would not admit the existence of a psychological distinction between reason and passion. According to their analysis, the emotions are so many different forms of judgment. Joy and sorrow are false opinions respecting good and evil in the present: desire and fear, false opinions respecting good and evil in the future.53 But, granting a righteous will to be the only good, and its absence the only evil, there can be no room for any of these feelings in the mind of a truly virtuous man, since his opinions on the subject of good are correct, and its possession depends entirely on himself. Everything else arises from an external necessity, to strive with which would be useless because it is inevitable, foolish because it is beneficent, and impious because it is supremely wise.
THREE:A distinct parallelism may be traced in the lines of evolution along which we have accompanied our two opposing schools. While the Academicians were coming over to the Stoic theory of cognition, the Stoics themselves were moving in the same general direction, and seeking for an external reality more in consonance with their notions of certainty than the philosophy of their first teachers could supply. For, as originally constituted, Stoicism included a large element of scepticism, which must often have laid its advocates open to the charge of inconsistency from those who accepted the same principle in a more undiluted form. The Heracleitean flux adopted by Zeno as the physical basis of his system, was164 much better suited to a sceptical than to a dogmatic philosophy, as the use to which it was put by Protagoras and Plato sufficiently proved; and this was probably the reason why Bothus and Panaetius partially discarded it in favour of a more stable cosmology. The dialectical studies of the school also tended to suggest more difficulties than they could remove. The comprehensive systematisation of Chrysippus, like that of Plato and Aristotle, had for its object the illustration of each topic from every point of view, and especially from the negative as well as from the positive side. The consequence was that his indefatigable erudition had collected a great number of logical puzzles which he had either neglected or found himself unable to solve. There would, therefore, be a growing inclination to substitute a literary and rhetorical for a logical training: and as we shall presently see, there was an extraneous influence acting in the same direction. Finally, the rigour of Stoic morality had been strained to such a pitch that its professors were driven to admit the complete ideality of virtue. Their sage had never shown himself on earth, at least within the historical period; and the whole world of human interests being, from the rational point of view, either a delusion or a failure, stood in permanent contradiction to their optimistic theory of Nature. The Sceptics were quite aware of this practical approximation to their own views, and sometimes took advantage of it to turn the tables on their opponents with telling effect. Thus, on the occasion of that philosophical embassy with an account of which the present chapter began, when a noble Roman playfully observed to Carneades, You must think that I am not a Praetor as I am not a sage, and that Rome is neither a city nor a state, the great Sceptic replied, turning to his colleague Diogenes, That is what my Stoic friend here would say.262 And Plutarch, in two sharp attacks on the Stoics, written from the Academic point of view, and probably165 compiled from documents of a much earlier period,263 charges them with outraging common sense by their wholesale practical negations, to at least as great an extent as the Sceptics outraged it by their suspense of judgment. How the ethical system of Stoicism was modified so as to meet these criticisms has been related in a former chapter; and we have just seen how Posidonius, by his partial return to the Platonic psychology, with its division between reason and impulse, contributed to a still further change in the same conciliatory sense.The articles alluded to were suggested by observations made in actual practice, and by noting a "habit of thought" common among learners, which did not seem to accord with the purely scientific manner in which mechanical subjects are now so constantly treated.
