Jean Piaget

“Scientific knowledge is in perpetual evolution; it finds itself changed from one day to the next.”

“The goal of education is not to increase the amount of knowledge but to create the possibilities for a child to invent and discover, to create men who are capable of doing new things.”

“It is with children that we have the best chance of studying the development of logical knowledge, mathematical knowledge, physical knowledge, and so forth.”

“In other words, knowledge of the external world begins with an immediate utilisation of things, whereas knowledge of self is stopped by this purely practical and utilitarian contact.”

“Scientific thought, then, is not momentary; it is not a static instance; it is a process.”

“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.”
