An interesting metaphor to describe the haphazard workings of genius, appearing like a beam illuminating the surrounding darkness at intervals, but without the pulsing regularity of the lighthouse. And in between their dazzling flashes, the genius withdraws into darkness of indeterminate duration and has little to distinguish them from other less brilliant people.
‘Rather it resembles the lighthouse in its working, which sends one ray and then no more for a time; save that genius is much more capricious in its manifestations and may flash six or seven beams in quick succession (as Mr Pope did that night) and then lapse into darkness for a year or for ever. To steer by its beams is therefore impossible, and when the dark spell is on them men of genius are, it is said, much like other people.’
