Beyng is the background against which entities can be uncovered and attain a stable, enduring presence. This background is dynamic and subject to change. In different historical ages it has different styles, each of which invisibly shapes how entities are constituted. “As an origin” or source of entities, Heidegger explains, “beyng is as a rift that clears away, a rift within which entities can come to a ‘stand’” (GA66:224).
