Classes, relations et nombres : essai sur les groupements de la logistique et sur la réversibilité de la pensée

In this essay, Piaget addresses the question of the foundations of mathematics from a perspective that is opposed to the theses of logical empiricism and symbolic logic. He shows that the structure of a group is based on the reversibility of thought and that its construction can be described as a result of the development of an elementary logical unit, the grouping.
