The same principle may be extended in a different direction if we substitute for knowledge, in its narrower significance, the more general conception of associated feeling. We shall then see that belief, habit, emotion, and instinct are only136 different stages of the same process—the process by which experience is organised and made subservient to vital activity. The simplest reflex and the highest intellectual conviction are alike based on sensori-motor mechanism, and, so far, differ only through the relative complexity and instability of the nervous connexions involved. Knowledge is life in the making, and when it fails to control practice fails only by coming into conflict with passion—that is to say, with the consolidated results of an earlier experience. Physiology offers another analogy to the Socratic method which must not be overlooked. Socrates recommended the formation of definite conceptions because, among other advantages, they facilitated the diffusion of useful knowledge. So, also, the organised associations of feelings are not only serviceable to individuals, but may be transmitted to offspring with a regularity proportioned to their definiteness. How naturally these deductions follow from the doctrine under consideration, is evident from their having been, to a certain extent, already drawn by Plato. His plan for the systematic education of feeling under scientific supervision answers to the first; his plan for breeding an improved race of citizens by placing marriage under State control answers to the second. Yet it is doubtful whether Plato’s predecessor would have sanctioned any scheme tending to substitute an external compulsion, whether felt or not, for freedom and individual initiative, and a blind instinct for the self-consciousness which can give an account of its procedure at every step. He would bring us back from social physics and physiology to psychology, and from psychology to dialectic philosophy. CAWNPORE From a quite small garden close to the palace a bronze gate with three medallions of lilies in high relief, of marvellous workmanship, opens on the Pearl Mosque, exquisitely white, at the end of its forecourt of immaculate pavement enclosed by a marble balustrade. Three polished and shining domes are supported by columns of snow made of a hard white marble, scarcely broken by [Pg 218]ornament, and carrying a roof hollowed into three vaults. The rings are still to be seen on the marble walls outside, to which, when the great Mogul came to prayer, curtains were attached made of gold net and spangled with diamonds and pearls. His library, that evening, made Sandy think of a “mass meeting of creditors or stockholders who have been tricked.” Cairness went on, back to the barracks, and sitting at the troop clerk's desk, made a memory sketch of her. It did not by any means satisfy him, but he kept it nevertheless. He hesitated still. "I don't doubt you," he told her. "Cairness never was a squaw-man," corrected Crook. But the cottage was shut. With its red-rotting roof between two tall chimneys it looked exactly like a rabbit's head between its ears; the windows were blind, though it was past seven o'clock, and though Reuben knocked at the door loudly, there was no one to be seen. He prowled once or twice round the house, fumbling handles and window-latches, but there was no way of getting in. He listened, but he could not hear a sound. He pictured Rose and Handshut in each other's arms, laughing at him in his wretchedness and their bliss—and all the time he wanted the woman's blood more than the man's. "Yes; I don't want him to think we're set on getting away—but, by gum, Bill! we are." "I think she said her name was Holgrave," replied the lady in a cold tone. "But indeed, my lord baron, you seem to be wondrously well acquainted with the faces and the handywork of your vassals' wives!" "But, my liege," continued Oakley, still kneeling, "there is one confined in this fortress for whom I would solicit freedom." HoME 性感乱仑黄色小说ENTER NUMBET 008www.xg1s5.com.cn
