Jean Piaget's Early Life:
Jean Piaget was born in Switzerland in 1896 and began showing an interest in the natural sciences at a very early age.

While his early career consisted of work in the natural sciences, it was during the 1920s that he began to move toward work as a psychologist. He married Valentine Châtenay in 1923 and the couple went on to have three children. Piaget's observations of his own children served as the basis for many of his later theories.

Piaget identified himself as a genetic epistemologist. "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," he explained in his book Genetic Epistemology. Epistemology is a branch of philosophy that is concerned with the origin, nature, extent, and limits of human knowledge. He was interested not only in the nature of thought, but in how it develops and understanding how genetics impact this process.
His early work with Binet's intelligence tests had led him to conclude that children think differently than adults. It was this observation that inspired his interest in understands how knowledge grows throughout childhood.
He suggested that children sort
