Not illustrated. 1902 edition. Excerpt: ...prolonged or intensified beyond a certain degree, it is at first accompanied and finally supplanted by a sensation of pain. Now, Weber's experiments have shown that these differences in sensation are not due to the excitation of distinct nerves, but to the differently combined excitation of the filaments of the same nerves. The difference between the sensation of contact and the sensation oftemperature depends upon the order in which the filaments of a particular nerve are set in vibration. And thus, as Fick observes, we may understand why it is difficult to distinguish between a prick from a needle and a minute burn from a spark of fire; for the nearer we approach to a truly elementary sensation, the more evanescent becomes the distinction between the compound sensation of temperature and that of mechanical contact. On the contrary, when a larger area of skin is suddenly rubbed or burned, so that enough nerves are brought into play to compound the elements of the sensations, then there is no difficulty in distinguishing the feeling of temperature from that of mechanical contact. From these and many other kindred facts, to which scanty justice is done by this cursory allusion, M. Taine very plausibly concludes that our ordinary tactile sensations are made up of little component psychical affections differing only in number, order, and duration; while, according as these elementary psychical states are differently compounded, they form conscious sensations which, as pre sented to consciousness, seem to be severally simple and distinct in kind.1 Throughout this remarkable analysis questions are suggested which can be completely answered only when physics and chemistry, as well as physiology and psychology, are much more advanced than...show more
