"Knowing reality means constructing systems of transformations that correspond, more or less adequately, to reality"
About this Quote
Piaget doesn’t romanticize “truth” as something you simply receive; he frames it as something you build. “Knowing reality” is an active verb here, closer to engineering than contemplation. The mind, in his view, isn’t a mirror. It’s a workshop that assembles “systems of transformations” - mental operations that let you rotate, reverse, combine, and predict. A child learning that water poured into a taller glass is still the same amount isn’t memorizing a fact; they’re acquiring a transformation (conservation) that makes the world reliably computable.
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.
