" The trails of light which they [moths] seemed to leave behind them in all kinds of curlicues and streamers and spirals..., did not really exist, explained Alphonso, but were merely phantom tracks created by the sluggish reaction of the human eye ,appearing to see a certain afterglow in the place from which the insect itself, shining for only the fraction of a second in the lamplight, had already gone. It was such unreal phenomena, said Alphonso, the sudden incursion of unreality into the real world, certain effects of light in the landscape spread out before us, or in the eye of a beloved person, that kindled our deepest feelings, or at least what we took for them.
