physical scientists of the age, as a reference to their lectures and textbooks will prove to anyone.
And, more than this, any intelligent physical scientist will tell you that science has every reason to believe that there are great fields of energy and force. The vibrations of these are far too high for even the delicate instruments of science to record, but they nevertheless exist and produce effects. It was only recently original: "the other day"; here meaning in recent historical memory, as X-rays were discovered in 1895. that science was able to "capture" X-rays original: "X-Rays" and other forms of high radioactivity, and yet these rays and forces had always existed. Tomorrow, science will perfect instruments capable of registering even higher forms of energy. And by and by, some scientist will perfect an instrument that will register and record the subtle vibrations of thought. Perhaps in time, someone will perfect that instrument so that it will not only record such thought vibrations and waves, but, like the phonograph, it will be able to reproduce and send forth similar vibrations so that others may feel the thoughts, just as they now hear the sounds from the phonograph. Such a prediction is no more miraculous original: "wonderful"; in this context, meaning "full of wonder" or "extraordinary." than the prediction of the telephone, the phonograph, the wireless telegraph, and various original: "sundry" other discoveries and inventions would have been a hundred years ago.
Did you ever think that there are colors that the eye cannot see, but which delicate instruments clear—
