Sir Jean William Fritz Piaget foi um epistemólogo suíço, considerado um dos mais importantes pensadores do século XX. Defendeu uma abordagem interdisciplinar para a investigação epistemológica e fundou a Epistemologia Genética, teoria do conhecimento com base no estudo da gênese psicológica do pensamento humano.

Estudou inicialmente biologia na Universidade de Neuchâtel onde concluiu seu doutorado, e posteriormente se dedicou à área de Psicologia, Epistemologia e Educação. Foi professor de psicologia na Universidade de Genebra de 1929 a 1954, e tornou-se mundialmente reconhecido pela sua revolução epistemológica. Durante sua vida Piaget escreveu mais de cinqüenta livros e diversas centenas de artigos.

Piaget também teve um considerável impacto no campo da ciência da computação. Seymour Papert usou o trabalho de Piaget como fundamentação ao desenvolver a linguagem de programação Logo. Alan Kay usou as teorias de Piaget como base para o sistema conceitual de programação Dynabook, que foi inicialmente discutido em Xerox PARC. Estas discussões levaram ao desenvolvimento do protótipo Alto, que explorou pela primeira vez os elementos do GUI, ou Interface Gráfica do Usuário, e influenciou a criação de interfaces de usuário a partir dos anos 1980.

Em 1919, viaja para Paris e começa a trabalhar no Instituto Jean-Jacques Rousseau, quando publica os primeiros artigos sobre a criança. O nascimento dos filhos amplia o convívio diário com a "criança pequena" e possibilita o registro de observações que geram novas hipóteses sobre as origens da cognição humana. Durante sua estadia em Paris, Piaget conhece Théodore Simon, que o convida a padronizar os "testes de raciocínio de Cyril Burt, desenvolvidos nos Estados Unidos, experiência que lhe permitiu delimitar um campo de estudos empíricos: o pensamento infantil e o raciocínio lógico. Como resultado desse trabalho, Piaget é convidado para o cargo de coordenador de pesquisas do Instituto, função que inclui a "Maison des Petits" .

„It is as his own mind comes into contact with others that truth will begin to acquire value in the child's eyes and will consequently become a moral demand that can be made upon him.“

— Jean Piaget
Context: !-- Every thought that enters the head of a child of 2-3 does so from the first in the form of a belief and not in the form of a hypothesis to be verified. Hence the very young child's almost systematic romancing as with others and to which one cannot yet give the name of pseudo-lie, so close is the connection between primitive romancing and assertive belief. Hence finally, the pseudo-lie, which is a sort of romancing used for other people, and serving to pull the child out of any straight due to circumstances, from which he deems it perfectly natural to extricate himself by inventing a story. Just as, from the intellectual point of view the child will elude a difficult question by means of an improvised myth to which he will give momentary credence, so from the moral point of view, an embarrassing situation will give rise to a pseudo-lie. Nor does this involve anything more than an application of the general laws of primitive child thought, which is directed towards its own satisfaction rather than to objective truth. -->It is as his own mind comes into contact with others that truth will begin to acquire value in the child's eyes and will consequently become a moral demand that can be made upon him. As long as the child remains egocentric, truth as such will fail to interest him and he will see no harm in transposing facts in accordance with his desires. Ch. 2 : Adult Constraint and Moral Realism <!-- p. 165 -->

„It is when the child is accustomed to act from the point of view of those around him, when he tries to please rather than to obey, that he will judge in terms of intentions.“

— Jean Piaget
Context: It is when the child is accustomed to act from the point of view of those around him, when he tries to please rather than to obey, that he will judge in terms of intentions. So that taking intentions into account presupposes cooperation and mutual respect. Only those who have children of their own know how difficult it is to put this into practice. Such is the prestige of parents in the eyes of the very young child, that even if they lay down nothing in the form of general duties, their wishes act as law and thus give rise automatically to moral realism (independently, of course, of the manner in which the child eventually carries out these desires). In order to remove all traces of moral realism, one must place oneself on the child's own level, and give him a feeling of equality by laying stress on one's own obligations and one's own deficiencies. In this way the child will find himself in the presence, not of a system of commands requiring ritualistic and external obedience, but of a system of social relations such that everyone does his best to obey the same obligations, and does so out of mutual respect. The passage from obedience to cooperation thus marks a progress analogous to that of which we saw the effects in the evolution of the game of marbles: only in the final stage does the morality of intention triumph over the morality of objective responsibility. When parents do not trouble about such considerations as these, when they issue contradictory commands and are inconsistent in the punishments they inflict, then, obviously, it is not because of moral constraint but in spite of and as a reaction against it that the concern with intentions develops in the child. Here is a child, who, in his desire to please, happens to break something and is snubbed for his pains, or who in general sees his actions judged otherwise than he judges them himself. It is obvious that after more or less brief periods of submission, during which he accepts every verdict, even those that are wrong, he will begin to feel the injustice of it all. Such situations can lead to revolt. But if, on the contrary, the child finds in his brothers and sisters or in his playmates a form of society which develops his desire for cooperation and mutual sympathy, then a new type of morality will be created in him, a morality of reciprocity and not of obedience. This is the true morality of intention and of subjective responsibility. <!-- In short, whether parents succeed in embodying it in family life or whether it takes root in spite of and in opposition to them, it is always cooperation that gives intention precedence over literalism, just as it was unilateral respect that inevitably provoked moral realism. Actually, of course, there are innumerable intermediate stages between these two attitudes of obedience and collaboration, but it is useful for the purposes of analysis to emphasize the real opposition that exists between them. Ch. 2 : Adult Constraint and Moral Realism <!-- p. 133 -->

„The only way of avoiding these individual refractions would lie in true cooperation, such that both child and senior would each make allowance for his own individuality and for the realities that were held in common.“

— Jean Piaget
Context: Every observer has noted that the younger the child, the less sense he has of his own ego. From the intellectual point of view, he does not distinguish between external and internal, subjective and objective. From the point of view of action, he yields to every suggestion, and if he does oppose to other people's wills — a certain negativism which has been called "the spirit of contradiction" — this only points to his real defenselessness against his surroundings. A strong personality can maintain itself without the help of this particular weapon. The adult and the older child have complete power over him. They impose their opinions and their wishes, and the child accepts them without knowing that he does so. Only — and this is the other side of the picture — as the child does not dissociate his ego from the environment, whether physical or social, he mixes into all his thoughts and all his actions, ideas and practices that are due to the intervention of his ego and which, just because he fails to recognize them as subjective, exercise a check upon his complete socialization. From the intellectual point of view, he mingles his own fantasies with accepted opinions, whence arise pseudo lies (or sincere lies), syncretism, and all the features of child thought. From the point of view of action, he interprets in his own fashion the examples he has adopted, whence the egocentric form of play we were examining above. The only way of avoiding these individual refractions would lie in true cooperation, such that both child and senior would each make allowance for his own individuality and for the realities that were held in common.

„In real life the child is in the presence, not of isolated acts, but of personalities that attract or repel him as a global whole.“

— Jean Piaget
Context: In real life the child is in the presence, not of isolated acts, but of personalities that attract or repel him as a global whole. He grasps people's intentions by direct intuition and cannot therefore abstract from them. He allows, more or less justly, for aggravating and attenuating circumstances. This is why the stories told by the children themselves often give rise to different evaluations from those suggested by the experimenter's stories. Ch. 2 : Adult Constraint and Moral Realism, § 1 : The Method <!-- p. 116 --> Ch. 2 : Adult Constraint and Moral Realism p. 132 -->

„If children fail to understand one another, it is because they think they understand one another.“

— Jean Piaget
Context: If children fail to understand one another, it is because they think they understand one another. The explainer believes from the start that the reproducer will grasp everything, will almost know beforehand all that should be known, and will interpret every subtlety. Children are perpetually surrounded by adults who not only know much more than they do, but who also do everything in their power to understand them, who even anticipate their thoughts and desires. Children, therefore... are perpetually under the impression that people can read their thoughts, and in extreme cases, can steal their thoughts away. It is obviously owing to this mentality that children do not take the trouble to express themselves clearly... This mentality does not contradict ego-centric mentality. Both arise from the belief of the child, the belief that he is the centre of the universe. These habits of thought account... for the remarkable lack of precision in the childish style. The Language and Thought of the Child (1923) Tr. Marjorie and Ruth Gabain (1926)

„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.“

— Jean Piaget
Context: 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. Ch. 2 : Adult Constraint and Moral Realism <!-- p. 185 -->

„It is somewhat humiliating, in this connection, to see how heavily traditional education sets about the task of making spelling enter into brains that assimilate with such ease the mnemonic contents of the game of marbles. But then, memory is dependent upon activity, and a real activity presupposes interest.“

— Jean Piaget
Context: Considering that the square game is only one of the five or ten varieties of the game of marbles, it is almost alarming in face of the complexity of rules and procedure in the square game, to think of what a child of twelve has to store away in his memory. These rules, with their overlapping and their exceptions, are at least as complex as the current rules of spelling. It is somewhat humiliating, in this connection, to see how heavily traditional education sets about the task of making spelling enter into brains that assimilate with such ease the mnemonic contents of the game of marbles. But then, memory is dependent upon activity, and a real activity presupposes interest. Ch. 1 : The Rules of the Game
