Plato’s Cave or Truman’s Dome?

Jim Carrey as Truman Burbank
The idea that the world around us may not be real reaches back to Plato, who wondered if what we see resembles the ﬂickering shadows on a cave wall.  The notion of creating deceptive artiﬁcial environments dates back at least as far as Descartes, who in the seventeenth century speculated on the philosophical implications of a sense-manipulating “demon”—effectively a pretechnological virtual-reality generator. A recent example is the movie The Truman Show (1999 [sic]) in which the protagonist is the unwitting star of a TV show, trapped under a fake domed sky.
