Jean Piaget /Swiss developmental psychologist and philosopher
August 9th 1896 - 16 September 1980 (aged 84)
How does knowledge grow? "His researches in developmental psychology and genetic epistemology had one unique goal: how does knowledge grow? His answer is that the growth of knowledge is a progressive construction of logically embedded structures superseding one another by a process of inclusion of lower less powerful logical means into higher and more powerful ones up to adulthood.
Therefore, children's logic and modes of thinking are initially entirely different from those of adults.Piaget's oeuvre is known all over the world and is still an inspiration in fields like psychology, sociology, education, epistemology, economics and law as witnessed in the annual catalogues of the Jean Piaget Archives. He was awarded numerous prizes and honorary degrees all over the world."
