17.007 Light itself is invisible

Page 8 Light itself is invisible

At night, with complete darkness, we do not see the things of the outer world, even when they stand close before our eyes. The material world, taken by itself, is invisible. To recognize it, light is needed. But also light itself, as paradoxical as it may also sound, is invisible. We never see the light itself with material eyes. The whole universe, the night sky, is filled by light, and still it appears to us, apart from the shining stars, completely dark, almost black. We do not see the light, but always only shining or illuminated things.
