To conclude from the presence of electric tensions in the earth’s atmosphere as an accompaniment of lightning, in the way first observed by Franklin, that lightning itself is an electrical process, is to be under the same kind of illusion that led men to attribute electrical characteristics to the human soul because its activity in the body was found to be accompanied by electrical processes in the latter. The identification of lightning with the electric spark is a case of a confusion between the upper and lower boundaries of nature, characteristic of the onlooker-consciousness. As such, it has stood in the way of a real understanding both of non-electrical natural phenomena and of electricity itself.
