The subject dropped, and we sat on in the dusk that was rapidly deepening into night. The door into the hall was open at our backs, and a panel of light from the lamps within was cast out to the terrace. Wandering moths, invisible in the darkness, suddenly became manifest as they fluttered into this illumination, and vanished again as they passed out of it. One moment they were there, living things with life and motion of their own, the next they quite disappeared. How inexplicable that would be, I thought, if one did not know from long familiarity, that light of the appropriate sort and strength is needed to make material objects visible.Philip must have been following precisely the same train of thought, for his voice broke in, carrying it a little further.'Look at that moth,' he said, 'and even while you look it has gone like a ghost, even as like a ghost it appeared. Light made it visible. And there are other sorts of light, interior psychical light which similarly makes visible the beings which people the darkness of our blindness.' (Expiation)
