Jean Piaget

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

Jean Piaget

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.

Jean Piaget

The principle 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.

Jean Piaget

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

Jean Piaget

This means that no single logic is strong enough to support the total construction of human knowledge.

Jean Piaget

Our problem, from the point of view of psychology and from the point of view of genetic epistemology, is to explain how the transition is made from a lower level of knowledge to a level that is judged to be higher.

Jean Piaget

Jean Piaget

Jean Piaget

Jean Piaget

In genetic epistemology, as in developmental psychology, too, there is never an absolute beginning.

Jean Piaget

The self thus becomes aware of itself, at least in its practical action, and discovers itself as a cause among other causes and as an object subject to the same laws as other objects.

Jean Piaget

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.

Jean Piaget

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