Now What Shall Come Of This

The order which the spaces first perceived potentially include must, before being distinctly apprehended by the mind, be woven into those spaces by a rather complicated set of intellectual acts. Panum, the German physiologist, relates that when, as a boy, he was etherized for neuralgia, the objects in the room grew extremely small and distant, before his field of vision darkened over and the roaring in his ears began. She may make our ears ring by the sound of a bell, or by a dose of quinine; make us see yellow by spreading a field of buttercups before our eyes, or by mixing a little santonine powder with our food; fill us with terror of certain surroundings by making them really dangerous, or by a blow which produces a pathological alteration of our brain. By a strong effort we can succeed in dispersing our attention impartially over our whole person, and then we feel the real shape of our body in a sort of unitary way.

If we raise and lower the gas alternately, the whole room and all the objects in it seem alternately to enlarge and contract. The whole history of witchcraft and early medicine is a commentary on the facility with which anything which chances to be conceived is believed the moment the belief chimes in with an emotional mood. Haschish produces strange perversions of the general sensibility. Section 1. General Terms of Use and Redistributing Project Gutenberg-tm electronic works 1.A.

It is only as objects become permanent and their relations fixed that discrepancies and contradictions are felt and must be settled in some stable way. And the primitive perceptions of space are certainly of an unordered kind. The concrete perceptions which it covers are figures, directions, positions, magnitudes, and distances. They will even say, at last, That their hearts are blameless. However, even allowing, as is doubtless true, that the event was a delusion of nerves first fatigued by overwork and then excited by this stimulant, there is one point which is still wholly inexplicable and highly interesting to me.

This element of constructiveness is present in a still higher degree, and carries with it the same consequences, when we deal with objective spaces too great to be grasped by a single look. 여기를 클릭, 자세히 보기, 링크 참조, 홈페이지 이동, 원문 보기, 관련 정보 will be enabled only with great effort to rotate the eye so as to look at objects lying far off to the right. When a circumscribed opacity in front of the retina keeps off part of the light from the portion which it covers, objects projected on that portion may seem but half as large as when their image falls outside of it. The greater extensiveness that the feeling of certain parts of the same surface has over other parts, and that one order of surface has over another (retina over skin, for example), may also to a certain extent be explained by the operation of the same factor. Distance-apart, too, is a simple sensation--the sensation of a line joining the two distant points: lengthen the line, you alter the feeling and with it the distance felt.

There is one more important than the rest, called its distance. If the edge of a card be pressed against the skin, the distance between its extremities will seem shorter than that between two compass-tips touching the same terminal points. Their spaces are interfused and at most fill the same vaguely objective world. It is an anatomical fact that the most spatially sensitive surfaces (retina, tongue, finger-tips, etc.) are supplied by nerve-trunks of unusual thickness, which must supply to every unit of surface-area an unusually large number of terminal fibres. But the variations of felt extension obey probably only a very rough law of numerical proportion to the number of fibres. Sometimes a single member will alter its proportion to the rest; or one's back, for instance, will appear entirely absent, as if one were hollow behind. Conversely, let 신규 회원 혜택 비교 converge on a single ink-spot on the glass, and then by alternate shutting of them let it be noted what objects behind the glass the spot covers to the right and left eye respectively.
