During the earliest stages the child perceives things like a solipsist who is unaware of himself as subject and is familiar only with his own actions.
During the first few months of an infant's life, its manner of taking the breast, of laying its head on the pillow, etc., becomes crystallized into imperative habits. This is why education must begin in the cradle.
With regard to moral rules, the child submits more or less completely in intention to the rules laid down for him, but these, remaining, as it were, external to the subject's conscience, do not really transform his conduct.
The child often sees only what he already knows. He projects the whole of his verbal thought into things. He sees mountains as built by men, rivers as dug out with spades, the sun and moon as following us on our walks.
The child of three or four is saturated with adult rules. His universe is dominated by the idea that things are as they ought to be, that everyone's actions conform to laws that are both physical and moral - in a word, that there is a Universal Order.
