"Knowing reality means constructing systems of transformations that correspond, more or less adequately, to reality"
About this Quote
The sly power of the line is the hedge: “more or less adequately.” Piaget smuggles epistemic humility into a sentence that might otherwise sound technocratic. Our models don’t become reality; they correspond to it, with varying fit. That’s a direct shot at both naive realism (“I see it, so I know it”) and pure relativism (“any interpretation is as good as any other”). Knowledge is judged by performance: does your constructed system hold up under change, counterexample, and new perspective?
Contextually, this is Piaget’s constructivism distilled: cognition develops through successive reorganizations of these transformation systems, from sensory-motor action to abstract operations. Subtext: objectivity isn’t a starting point; it’s an achievement. You earn “reality” by continually revising the machinery in your head until it can survive contact with the world - and with other minds testing it.

Evidence: Knowing reality means constructing systems of transformations that correspond, more or less adequately, to reality. (p. 15 (in some editions; also appears early in the book’s introductory section)). This wording appears verbatim in Jean Piaget’s own text in the English book commonly cited as *Genetic Epistemology* (often cited bibliographically as Piaget, 1970). The same passage also exists in French as: “Connaître la réalité, c’est construire des systèmes de transformations qui correspondent plus ou moins idéalement à la réalité.” A publicly available French rendering of the same paragraph is hosted by the University of Geneva Piaget archive, but your requested English sentence is directly verifiable in the PDF above.
