"Creatures are not born
with desires unless satisfaction for those
desires exists. A baby feels hunger: well,
there is such a thing as food. A duckling
wants to swim: well, there is such a thing as
water. Men feel sexual desire: well, there is
such a thing as sex. If I find in myself a desire
which no experience in this world can
satisfy, the most probable explanation is that
I was made for another world. If none of my
earthly pleasures satisfy it, that does not
mean that the universe is a fraud. Probably
earthly pleasures were never meant to
satisfy it, but only to arouse it, to suggest
the real thing.
—C. S. Lewis
