Originally published in 1974, a wide and interesting set of intellectual abilities in children are examined here. Volume 1 of 4 converts an axiomatization of classes and asymmetrical relationships (proper to Piaget’s discipline of Genetic Epistemology) into a model of the development of these notions in children.
