Parenting & Family Quote by Jean Piaget

Piaget lands a deliberately unsettling comparison: the infant as a solipsist, sealed inside a private universe, not out of philosophy but out of developmental limitation. The line works because it borrows a term from epistemology to dramatize something stubbornly practical: early cognition is action-first. Before a child can treat the self as an object of thought, the world shows up as a series of doings - grasping, sucking, kicking - and whatever changes those doings seem to produce. There is experience, but not yet the reflective architecture that tags experience as "mine" in contrast to "not-mine."

The subtext is a quiet downgrade of adult common sense. Adults assume perception is basically a camera that grows sharper over time. Piaget insists it is more like a tool that learns its own handle. That phrase "unaware of himself as subject" is the hinge: subjecthood, in his account, is an achievement, not a birthright. The child is "familiar only with his own actions" because action is the first stable currency of meaning. Objects become "real" not when they are seen, but when they can be reliably acted upon and later re-found (his famous object permanence).

Context matters: Piaget is outlining his constructivist project, opposing both passive empiricism and nativist shortcuts. Calling the child a solipsist is not an insult; it's a rhetorical provocation. He wants you to feel how alien early mind is, so you stop projecting adult categories onto it - and start taking development seriously as a staged conquest of reality.
