What really shapes and conditions and makes us is somebody only a few of
us ever have the courage to face: and that is the child you once were,
long before formal education ever got its claws into you -- that
impatient, all-demanding child who wants love and power and can't get
enough of either and who goes on raging and weeping in your spirit till
at last your eyes are closed and all the fools say, "Doesn't he look
peaceful?" It is those pent-up, craving children who make all the wars
and all the horrors and all the art and all the beauty and discovery in
life, because they are trying to achieve what lay beyond their grasp
before they were five years old.
-- Robertson Davies, "The Rebel Angels"
