Jean Piaget Quotes

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

Formal logic, or logistics, is simply the axiomatics of states of equilibrium of thought, and the positive science corresponding to this axiomatics is none other than the psychology of thought.

The child who defines a lie as being a "naughty word" knows perfectly well that lying consists in 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".

In certain circumstances where he experiments in new types of conduct by cooperating with his equals, the child is already an adult. There is an adult in every child and a child in every adult. … There exist in the child certain attitudes and beliefs which intellectual development will more and more tend to eliminate: there are others which will acquire more and more importance. The later are not derived from the former but are partly antagonistic to them.

Egocentrism in so far as it means confusion of the ego and the external world, and egocentrism in so far as it means lack of cooperation, constitute one and the same phenomenon. So long as the child does not dissociate his ego from the suggestions coming from the physical and from the social world, he cannot cooperate, for in order to cooperate one must be conscious of one's ego and situate it in relation to thought in general. And in order to become conscious of one's ego, it is necessary to liberate oneself from the thought and will of others. The coercion exercised by the adult or the older child is therefore inseparable from the unconscious egocentrism of the very young child.

A child’s first geometrical discoveries are topological. If you ask him to copy a square or a triangle, he draws a closed circle.

To perceive is to construct intellectually, and if the child draws things as he conceives them, it is certainly because he cannot perceive them without conceiving them. But to give up gradually the spurious absolutes situated away and apart from the context of relations that has been built up during experience itself is the work of a superior kind of rationality. When the child comes to draw things as he sees them, it will be precisely because he has given up taking isolated objects in and for themselves and has begun to construct real systems of relations which take account of the true perspective in which things are connected.

Psychology, in fact, repre-
sents the juncture of two opposite directions of are still insufficient. In the science of human be- scientific thought that are dialectically comple-
mentary. It follows that the system of sciences
cannot be arranged in a linear order, as many
people beginning with Auguste Comte have at-
tempted to arrange them.

In fact, objects are known only through the subject, while the subject can know himself or her- self only by acting on objects materially and mentally. Indeed, if objects are innumerable and science indefinitely diverse, all knowledge of the subject brings us back to psychology, the science of the subject and the subject's actions.

Every psychological explanation comes sooner or later to lean either on biology or on logic (or on sociology, but this in turn leads to the same alternatives).

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.

Children should be able to do their own experimenting and their own research. Teachers, of course, can guide them by providing appropriate materials, but the essential thing is that in order for a child to understand something, he must construct it himself, he must re-invent it. Every time we teach a child something, we keep him from inventing it himself. On the other hand that which we allow him to discover by himself will remain with him visibly for the rest of his life.

Alongside of the rare cases of true conversation where there is a genuine interchange of opinions or commands, one can observe in children between 2 and 6 a characteristic type of pseudo-conversation or "collective monologue", during which the children speak only for themselves, although they wish to be in the presence of interlocutors who will serve as a stimulus. Now here again, each feels himself to be in communion with the group because he is inwardly addressing the Adult who knows and understands everything, but here again, each is only concerned with himself, for lack of having dissociated the "ego" from the "socius".

In fact, objects are known only through the subject, while the subject can know himself or her- self only by acting on objects materially and men- tally. Indeed, if objects are innumerable and sci- ence indefinitely diverse, all knowledge of the sub- ject brings us back to psychology, the science of the subject and the subject's actions.
The fourth remark: People may say that I thus engage in philosophy or epistemology and no longer in scientific psychology. But, in the research that we pursue, it is impossible to dissociate psychology from epistemology. Indeed, if we study only one level of development (for example, that of the adult or adolescent), it is easy to distinguish the prob- lems: psychological experience, emotions, intelli- gence and its functions, etc., on the one hand, and the broad problems of knowledge (epistemology), etc., on the other. But if we want to study cogni- tive functions and pursue a developmental point of view in order to study the formation and trans- formations of human intelligence (and this is why I specialized in child psychology), then the prob-
lems must be formulated very differently: How is knowledge acquired, how does it increase, and how does it become organized or reorganized? These are the very questions that must be answered.

Play is the work of childhood.
