As it often does

“Very early in life, even before the infant can speak, its conduct is constantly being subjected to approval or censure. According to circumstances people are pleased with baby and smile at it, or else frown and leave it to cry, and the very inflections in the voices of those that surround it are alone sufficient to constitute an incessant retribution. During the years that follow, the child is watched over continuously, everything he does and says is controlled, gives rise to encouragement or reproof, and the vast majority of adults still look upon punishment, corporal or otherwise, as perfectly legitimate. It is obviously these reactions on the part of the adult, due generally to fatigue or impatience, but often, too, coldly thought out on his part, it is obviously these adult reactions, we repeat, that are the psychological starting point of the idea of expiatory punishment. If the child felt nothing but fear or mistrust, as may happen in extreme cases, this would simply lead to open war.” – Jean Piaget, The Moral Judgment of the Child (trans. Marjorie Gabain)
