Jean Piaget

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

“To understand is to invent.”

“Every acquisition of accommodation becomes material for assimilation, but assimilation always resists new accommodations.”

“The current state of knowledge is a moment in history, changing just as rapidly as the state of knowledge in the past has ever changed and, in many instances, more rapidly.”

“Children require long, uninterrupted periods of play and exploration.”

“The principal goal of education in the schools should be creating men and women who are capable of doing new things, not simply repeating what other generations have done.”

“Logic and mathematics are nothing but specialized linguistic structures.”

“From the moral as from the intellectual point of view, the child is born neither good nor bad but master of his destiny.”

“If you want to be creative, stay in part a child, with the creativity and invention that characterizes children.”

“To express the same idea in two different ways is to enrich it.”

“Intelligence is what you use when you don't know what to do.”

“What we see changes what we know. What we know changes what we see.”

“Knowing reality means constructing systems of transformations that correspond, more or less adequately, to reality.”

“Children have real understanding only of that which they invent themselves.”

“Play is the work of childhood.”

“Our problem is, what is the goal of education? Are we forming children that are only capable of learning what is already known?”

“A truth is a truth, and it's not a matter of consensus or voting.”
