The idealists argue that the hexagonal rooms are a
necessary form of absolute space or, at least, of our
intuition of space. They reason that a triangular or
pentagonal room is inconceivable. (The mystics claim that
their ecstasy reveals to them a circular chamber containing
a great circular book, whose spine is continuous and which
follows the complete circle of the walls; but their testimony
is suspect; their words, obscure. This cyclical book is God.)
Let it suffice now for me to repeat the classic dictum: The
Library is a sphere whose exact center is any one of its
hexagons and whose circumference is inaccessible.
