Abstract
This article proposes a comparative approach between childhood notions of Jean Piaget and infancy in Sigmund Freud, it takes as basic concepts the notion of time and moral in both authors. It claims to be possible to state, from a reading of genetic epistemology, that childhood will be transformed as we act and we know according to operative cognitive structures. However, according to psychoanalysis, it is possible to refer to infancy, also present in adulthood. The infancy escapes the rationality that underlies to that notion of Piaget's structure. The permanence of the infancy is a source of creative experiences and the establishment of a permanent movement of subjectivity.
