FORE:Even the very imperfect means of information supplied by the literature of the empire were not utilised to the fullest extent. It was naturally the writers of most brilliant genius who received most attention, and these, as it happened, were the most prejudiced against their contemporaries. Their observations, too, were put on record under the form of sweeping generalisations; while the facts from which a different conclusion might be gathered lay scattered through the pages of more obscure authorities, needing to be carefully sifted out and brought together by those who wished to arrive at a more impartial view of the age to which they relate.
FORE:CHAPTER I. THE STOICS.
FORE:Here I also saw in action one of the 30?5 cm. Austrian howitzers mentioned before. The clumsy204 monster was constantly being shunted on a rail forward and backward, and at long intervals sent a gigantic projectile to the threatened quarters. The sound was terrific, and the pressure of the air made people at a great distance tremble on the ground. The Austrian artillerists were still equipped as if they had to fight in a rough, mountainous country; the soles of their shoes were all over covered with hobnails.Attention has been called to this case as one wherein the conditions of operation obviously furnish true data to govern the arrangement of machinery, instead of the determinable strains to which the parts are subjected, and as a good example of the importance of studying mechanical conditions from a practical and experimental point of view. If the general diameter of a shaft is based upon the exact amount of power to be transmitted, or if the diameter of a shaft at various parts is based upon the torsional stress that would be sustained at these points, such a shaft would not only fail to meet the conditions of practical use, but would cost more by attempting such an adaptation. The regular working strain to which shafts are subjected is inversely as the speed at which they run. This becomes a strong reason in favour of arranging shafts to run at a maximum speed, provided there was nothing more than first cost to consider; but there are other and more important conditions to be taken into account, principal among which are the required rate of movement where power is taken off to machines, and the endurance of bearings.
THREE:The truths here touched on seem to have been dimly present to the mind of Plato. He never doubts that all knowledge must, in some way or other, be derived from experience; and, accordingly, he assumes that what cannot have been learned in this world was learned in another. But he does not (in the Meno at least) suppose that the process ever had a beginning. It would seem that he is trying to express in figurative language the distinction, lost almost as soon as found, between intelligence and the facts on which intelligence is exercised, An examination of the steps by which Menos slave is brought to perceive, without being directly told, the truth of the Pythagorean theorem, will show that his share in the demonstration is limited to the intuition of certain numerical equalities and inequalities. Now, to Plato, the perception of sameness and difference meant everything. He would have denied that the sensible world presented examples of these relations in their ideal absoluteness and purity. In tracing back their apprehension to the self-reflection of the soul, the consciousness of personal identity, he would not have transgressed the limits of a legitimate enquiry. But self-consciousness involved a possible abstraction from disturbing influences, which he interpreted as a real separation between mind and matter; and, to make it more complete, an inde213pendent pre-existence of the former. Nor was this all. Since knowledge is of likeness in difference, then the central truth of things, the reality underlying all appearance, must be an abiding identity recognised by the soul through her previous communion with it in a purer world. The inevitable tendency of two identities, one subjective and the other objective, was to coalesce in an absolute unity where all distinctions of time and space would have disappeared, carrying the whole mythical machinery along with them; and Platos logic is always hovering on the verge of such a consummation without being able fully to accept it. Still, the mystical tendency, which it was reserved for Plotinus to carry out in its entirety, is always present, though restrained by other motives, working for the ascertainment of uniformity in theory and for the enforcement of uniformity in practice."No use making a noise here," said Prout coolly. "It was a good idea of yours to hide yourself amongst respectable working men."
