“A mechanism that enables the individual or collective subject to escape any form of distorting subjectivity, because it is egocentric or sociocentric, in order to achieve various forms of objectivity in its relationship to the world or to others.”
Fondation Jean Piaget, website, Notions.
Process leading from egocentrism and phenomenism to objectivity, from the individual subject (distorting subjectivity) to the epistemic subject (structuring activity). This decentering of the subject takes place in relation to his or her own perspective (egocentrism), and in relation to the most immediate appearances of objects (phenomenism).
