Page 423 - ... thinks about it the more he is baffled. Similarly, though analysis of mental actions may finally bring him down to sensations as the original materials out of which all thought is woven, he is none the forwarder ; for he cannot in the least comprehend sensation — cannot even conceive how sensation is possible.
Page 52 - The working of the model by hand at once showed that there was only one period of working at which the motion of the water in the model would imitate the motions of the actual tide in the Mersey, which period was found to be about forty...
Page 423 - When, again, he turns from the succession of phenomena, external or internal, to their essential nature, he is equally at fault. Though he may succeed in resolving all properties of objects into manifestations of force, he is not thereby enabled to...
Page 423 - He learns at once the greatness and the littleness of the human intellect— its power in dealing with all that comes within the range of experience ; its impotence in dealing with all that transcends experience. He realizes with a special vividness the utter incomprehensibleness of the simplest fact, considered in itself.
Page 423 - Ultimate Scientific Ideas, then, are all representative of realities that cannot be comprehended. After no matter how great a progress in the colligation of facts and the establishment of generalizations ever wider and wider — after the merging of limited and derivative truths in truths that are larger and deeper has been carried no matter how far ; the fundamental truth remains as much beyond reach as ever.
Page 423 - Thus neither when considered in connexion with Space, nor when considered in connexion with Matter, nor when considered in connexion with Rest, do we find that Motion is truly cognizable. All efforts to understand its essential nature do but bring us to alternative impossibilities of thought.
Page 52 - The calculated period of this model is 80 seconds, and experiment bears this out, any variation leading to some tidal phenomena, such as bores or standing waves, which are not observed in the estuary. "On one occasion the model was kept going for 6,000 tides and a survey was then made of the state of the sand. And this will be seen to present a remarkable resemblance to the charts of the Mersey...
Page 423 - Alike in the external and the internal worlds, the man of science sees himself in the midst of perpetual changes of which he can discover neither the beginning nor the end. If, tracing back the evolution of things, he allows himself to entertain the hypothesis that...
Page 54 - As a matter of fact, however, it does not seem to do so. And, further, it would seem that, notwithstanding the general resemblance on the regime of the beds of large and small streams running over sand, there is in these a similar difference in vertical scale, the smaller streams not only having a greater slope, but also having greater depth as compared with their breadth and steeper banks.
Page 52 - ... further changes in detail going on in the estuary, the two sides maintained a steady condition as regards depth for low tides. During this time banks were formed and low-tide channels, which resembled in all the principal features those actually in the Mersey ; the eastern bank, with the deep sloynes on the Cheshire side, the Devil's Bank and the Garston Channel, the Ellesmere Channel and the deep water in Dungeon Bay and at Dingle Point— all these were very marked in character and closely...
