These men are terrible, when one encounters them, or catches a glimpse of them, towards midnight, on a deserted boulevard. They do not seem to be men but forms composed of living mists; one would say that they habitually constitute one mass with the shadows, that they are in no wise distinct from them, that they possess no other soul than the darkness, and that it is only momentarily and for the purpose of living for a few minutes a monstrous life, that they have separated from the night.
What is necessary to cause these spectres to vanish? Light. Light in floods. Not a single bat can resist the dawn. Light up society from below.
