'As Far as Thought Can Reach: A.D. 31,920' is a play written by George Bernard Shaw. It is set in a time when short-lived people are a mere footnote in ancient history, and great longevity is the norm. The opening scene is a sunlit glade at the foot of thickly wooded hill, on a warm summer afternoon in 31,920 AD. On the west side stands a little classic temple and in the middle of the glade there is a marble altar, shaped like a table, and long enough for a man to lie on. Rows of curved marble benches, spaced well apart, fan out from the altar. A path with stairs of rough-cut stone leads upward from the temple to the hill.
