Frases de Jean Piaget
Data de nascimento: 9. Agosto 1896

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" .
Citações Jean Piaget
„There are no really solipsistic philosophers, and those who think they are deceive themselves. The true solipsist feels at one with the universe, and so very identical to it that he does not even feel the need for two terms.“
— Jean Piaget
Context: There are no really solipsistic philosophers, and those who think they are deceive themselves. The true solipsist feels at one with the universe, and so very identical to it that he does not even feel the need for two terms. The true solipsist projects all his states of mind onto things. The true solipsist is entirely alone in the world, that is, he has no notion of anything exterior to himself. In other words the true solipsist has no idea of self. There is no self: there is the world. It is in this sense it is reasonable to call a baby a solipsist: the feelings and desires of a baby know no limits since they are a part of everything he sees, touches, and perceives. Babies are, then, obviously narcissistic, but not in the way adults are, not even Spinoza's God, and I am a little afraid that Freud sometimes forgets that the narcissistic baby has no sense of self. Given this definition of solipsism, egocentrism in children clearly appears to be a simple continuation of solipsism in infants.. Egocentrism, as we have seen, is not an intentional or even a conscious process. A child has no idea that he is egocentric. He believes everybody thinks the way he does, and this false universality is due simply to an absence of the sense of limits on his individuality. In this light, egocentrism and solipsism are quite comparable: both stem from the absence or the weakness of the sense of self.

„It is perhaps in this domain that one realized most how keenly how immoral it can be to believe too much in morality, and how much more precious is a little humanity than all the rules in the world.“
— Jean Piaget
Context: The majority of parents are poor psychologists and give their children the most questionable moral trainings. It is perhaps in this domain that one realized most how keenly how immoral it can be to believe too much in morality, and how much more precious is a little humanity than all the rules in the world. Thus the adult leads the child to the notion of objective responsibility, and consolidates in consequence a tendency that is already natural to the spontaneous mentality of little children.

„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.“
— 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.

— Jean Piaget
Context: Knowing reality means constructing systems of transformations that correspond, more or less adequately, to reality. They are more or less isomorphic to transformations of reality. The transformational structures of which knowledge consists are not copies of the transformations in reality; they are simply possible isomorphic models among which experience can enable us to choose. Knowledge, then, is a system of transformations that become progressively adequate.

„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.“
— 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 -->
„The intentionality peculiar to motor activity is not a search for truth but the pursuit of a result, whether objective or subjective; and to succeed is not to discover a truth.“
— Jean Piaget
Context: Generally speaking, one can say that motor intelligence contains the germs of completed reason. But it gives promise of more than reason pure and simple. From the moral as from the intellectual point of view, the child is born neither good nor bad, but master of his destiny. Now, if there is intelligence in the schemas of motor adaptation, there is also the element of play. The intentionality peculiar to motor activity is not a search for truth but the pursuit of a result, whether objective or subjective; and to succeed is not to discover a truth. Ch. 2 : Adult Constraint and Moral Realism <!-- p. 93 -->
„Between the various types of rules which we shall give there will therefore be at once continuity of function and difference of structure.“
— Jean Piaget
Context: Between the various types of rules which we shall give there will therefore be at once continuity of function and difference of structure. This renders arbitrary any attempt to cut mental reality up into stages. The matter is further complicated by the "Law of conscious realization" and the resulting time-lag. The appearance of a new type of rule on the practical plane does not necessarily mean that this rule will come into the subject's consciousness, for each mental operation has to be relearned on the different planes of action and of thought.
