“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 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 prove that the universe is a fraud.

Probably earthly pleasures were never meant to satisfy it, but only arouse it, to suggest the real thing.”

~ CS Lewis from Mere Christianity
