TWO:"What time would that be?" Bruce asked as casually as possible.
THREE:We have now reached the great point on which the Stoic ethics differed from that of Plato and Aristotle. The two latter, while upholding virtue as the highest good, allowed external advantages like pleasure and exemption from pain to enter into their definition of perfect happiness; nor did they demand the entire suppression of passion, but, on the contrary, assigned it to a certain part in the formation of character. We must add, although it was not a point insisted on by the ancient critics, that they did not bring out the socially beneficent character of virtue with anything like the distinctness of their successors. The Stoics, on the other hand, refused to admit that there was any good but a virtuous will, or that any useful purpose could be served by irrational feeling. If the passions agree with virtue they are superfluous, if they are opposed to it they are mischievous; and once we give them the rein they are more likely to disagree with than to obey it.5222 The severer school had more reason on their side than is commonly admitted. Either there is no such thing as duty at all, or duty must be paramount over every other motivethat is to say, a perfect man will discharge his obligations at the sacrifice of every personal advantage. There is no pleasure that he will not renounce, no pain that he will not endure, rather than leave them unfulfilled. But to assume this supremacy over his will, duty must be incommensurable with any other motive; if it is a good at all, it must be the only good. To identify virtue with happiness seems to us absurd, because we are accustomed to associate it exclusively with those dispositions which are the cause of happiness in others, or altruism; and happiness itself with pleasure or the absence of pain, which are states of feeling necessarily conceived as egoistic. But neither the Stoics nor any other ancient moralists recognised such a distinction. All agreed that public and private interest must somehow be identified; the only question being, should one be merged in the other, and if so, which? or should there be an illogical compromise between the two. The alternative chosen by Zeno was incomparably nobler than the method of Epicurus, while it was more consistent than the methods of Plato and Aristotle. He regarded right conduct exclusively in the light of those universal interests with which alone it is properly concerned; and if he appealed to the motives supplied by personal happiness, this was a confusion of phraseology rather than of thought.It remains to be seen whether the system which we are examining is consistent with itself. It is not. The Prime Mover, being unextended, cannot be located outside the sidereal sphere; nor can he be brought into immediate contact with it more than with any other part of the cosmos. If the aether has a motion proper to itself, then no spiritual agency is required to keep it in perpetual rotation. If the crystalline spheres fit accurately together, as they must, to avoid leaving a vacuum anywhere, there can be no friction, no production of heat, and consequently no effect produced on the sublunary sphere. Finally, no rotatory or other movement can, taken alone, have any conceivable connexion with the realisation of a possibility, in the sense of progress from a lower to a higher state of being. It is merely the perpetual exchange of one indifferent position for another.
THREE:In no other branch of machinery has so much research and experiment been made during eighty years past as in steam machinery, and, strange to say, the greater part of this research has been directed to the details of engines; yet there has been no improvement made during the time which has effected any considerable saving of heat or expense. The steam-engines of fifty years ago, considered as steam-using machines, utilised nearly the same proportion of the energy or power developed by the boiler as the most improved engines of modern constructiona fact that in itself indicates that an engine is not the vital part of steam machinery. There is not the least doubt that if the efforts to improve steam-engines had been mainly directed to economising heat and increasing the evaporative power of boilers, much more would have been accomplished with the same amount of research. This remark, however, does not apply to the present day, when the principles of steam-power are so well understood, and when heat is recognised as the proper element to deal with in attempts to diminish the expense of power. There is, of course, various degrees of economy in steam-using as well as in steam-generating machinery; but so long as the best steam machinery does not utilise but one-tenth or one-fifteenth part of the heat represented in the fuel burned, there need be no question as to the point where improvements in such machinery should be mainly directed.
THREE:Sandy did not smile. Instead, as they swung, he scanned the sky. That was not his instructions, but it was his determined plan.
