“Creatures are not born with desires unless satisfaction for those desires exist. A baby feel hunger…well, there is such a thing as food. A duckling wants to swim; there is such a thing as water.”
“If I find in myself a desire which no experience in this world can satisfy, the most probably explanation is that I am made for another world. If none of my early pleasures satisfy it, that does not prove 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
