"The child who defines a lie as 'a naughty word' knows perfectly well that lying consists of not speaking the truth. He is not, therefore, mistaking one thing for another; he is simply identifying them one with another by what seems to us a quaint extension of the word lie."

— from The Moral Judgment of the Child, 1932

"The more the schemata are differentiated, the smaller the gap between the new and the familiar becomes, so that novelty, instead of constituting an annoyance avoided by the subject, becomes a problem and invites searching."

— from The Origins of Intelligence in Children, 1936

"Knowledge is not a copy of reality. To know an object, to know an event, is not simply to look at it and record it in a mental image or even to make a perceptual copy of it. To know an object is to act on it."

— from Speech at UNESCO, 'Science of Education and the Psychology of the Child', 1964
