I have called my material surroundings a stage set. In this I can act. And you may well say “act”. For what I call “myself” (for all practical, everyday purposes) is also a dramatic construction; memories, glimpses in the shavinglass, and snatches of the very fallible activity called “introspection”, are the principal ingredients. Normally I call this construction “me”‘ and the stage set “the real world”. … I cannot, in the flesh, leave the stage, either to go behind the scenes or to take my seat in the pit; but I can remember that these regions exist.

C.S. Lewis (1898-1963) English writer and scholar [Clive Staples Lewis]
