With the idea of subsumption and subordination to law, we pass at once to the Stoic ethics. For Zeno, the end of life was self-consistency; for Cleanthes, consistency with Nature; for Chrysippus, both the one and the other.42 The still surviving individualism of the Cynics is represented in the first of these principles; the religious inspiration of the Stoa in the second; and the comprehensiveness of its great systematising intellect in the last. On the other hand, there18 is a vagueness about the idea of self-consistency which seems to date from a time when Stoicism was less a new and exclusive school than an endeavour to appropriate whatever was best in the older schools. For to be consistent is the common ideal of all philosophy, and is just what distinguishes it from the uncalculating impulsiveness of ordinary life, the chance inspirations of ordinary thought. But the Peripatetic who chose knowledge as his highest good differed widely from the Hedonist who made pleasure or painlessness his end; and even if they agreed in thinking that the highest pleasure is yielded by knowledge, the Stoic himself would assert that the object of their common pursuit was with both alike essentially unmoral. He would, no doubt, maintain that the self-consistency of any theory but his own was a delusion, and that all false moralities would, if consistently acted out, inevitably land their professors in a contradiction.43 Yet the absence of contradiction, although a valuable verification, is too negative a mark to serve for the sole test of rightness; and thus we are led on to the more specific standard of conformability to Nature, whether our own or that of the universe as a whole. Here again a difficulty presents itself. The idea of Nature had taken such a powerful hold on the Greek mind that it was employed by every school in turnexcept perhaps by the extreme sceptics, still faithful to the traditions of Protagoras and Gorgiasand was confidently appealed to in support of the most divergent ethical systems. We find it occupying a prominent place both in Platos Laws and in Aristotles Politics; while the maxim, Follow Nature, was borrowed by Zeno himself from Polemo, the head of the Academy, or perhaps from Polemos predecessor, Xenocrates. And Epicurus, the great opponent of Stoicism, maintained, not without plausibility, that every19 animal is led by Nature to pursue its own pleasure in preference to any other end.44 Thus, when Cleanthes declared that pleasure was unnatural,45 he and the Epicureans could not have been talking about the same thing. They must have meant something different by pleasure or by nature or by both.
FORE:CHAPTER XXXVI. A FAINT CLUE.And Gilbert Lawrence now refused to say anything. He was the one person who seemed to be thoroughly satisfied. There was some comfort to be derived from this, but not much, as Hetty told herself miserably.
"That way? But how did you get here then?"Nor was this all. As the world of sense was coming back into favour, the world of reason was falling into disrepute. Just as the old physical philosophy had been decomposed by the Sophisticism of Protagoras and Gorgias, so also the dialectic of Socrates was corrupted into the sophistry of Eubulides and Euthydmus. Plato himself discovered that by reasoning deductively from purely abstract premises, contradictory conclusions could be established with apparently323 equal force. It was difficult to see how a decision could be arrived at except by appealing to the testimony of sense. And a moral reform could hardly be effected except by similarly taking into account the existing beliefs and customs of mankind.There is one more aspect deserving our attention, under which the theory of Nature has been presented both in ancient and modern times. A dialogue which, whether rightly or wrongly attributed to Plato, may be taken as good evidence on the subject it relates to,65 exhibits Hippias in the character of a universal genius, who can not only teach every science and practise every kind of literary composition, but has also manufactured all the clothes and other articles about his person. Here we have precisely the sort of versatility which characterises uncivilised society, and which believers in a state of nature love to encourage at all times. The division of labour, while it carries us ever farther from barbarism, makes us more dependent on each other. An Odysseus is master of many arts, a Themistocles of two, a Demosthenes of only one. A Norwegian peasant can do more for himself than an English countryman, and therefore makes a better colonist. If we must return to Nature, our first step should be to learn a number of trades, and so be better able to shift for ourselves. Such was the ideal of Hippias, and it was also the ideal of the eighteenth century. Its literature begins with Robinson Crusoe, the story of a man who is accidentally compelled to provide himself, during many years, with all the necessaries of life. Its educational manuals are, in France, Rousseaus mile; in England, Days Sandford and Merton, both teaching that the young should be thrown as much as possible on their own resources. One of its types is Diderot, who learns handicrafts that he may describe them in the Encyclopdie. Its two great spokesmen are Voltaire and Goethe, who, after cultivating every department of literature, take in statesmanship as well. And its last word is Schillers Letters on Aesthetic Culture, holding up totality of existence as the supreme ideal to be sought after.2. The use that may be made of air after it has been applied as a motive agent.Count Rumford did not by chance develope the philosophy of forces upon which we may say the whole science of dynamics now rests; he set out upon a methodical plan to demonstrate conceptions that were already matured in his mind, and to verify principles which he had assumed by inductive reasoning. The greater part of really good and substantial improvements, such as have performed any considerable part in developing modern mechanical engineering, have come through this course of first dealing with primary principles, instead of groping about blindly after mechanical expedients, and present circumstances point to a time not far distant when chance discovery will quite disappear.
