Jean Piaget
Main article: Jean PiagetDate: 1896-1980
Jean Piaget was a Swiss developmental psychologist known for his epistemological studies with children. His theory of cognitive development and epistemological view are together called "genetic epistemology". Piaget placed great importance on the education of children. As the Director of the International Bureau of Education, he declared in 1934 that "only education is capable of saving our societies from possible collapse, whether violent, or gradual." Piaget created the International Centre for Genetic Epistemology in Geneva in 1955 and directed it until 1980. According to Ernst von Glasersfeld, Jean Piaget is "the great pioneer of the constructivist theory of knowing."
Jean Piaget described himself as an epistemologist, interested in the process of the qualitative development of knowledge. As he says in the introduction of his book "Genetic Epistemology" (ISBN 978-0-393-00596-7): "What the genetic epistemology proposes is discovering the roots of the different varieties of knowledge, since its elementary forms, following to the next levels, including also the scientific knowledge."
