There is always a tension in Piaget's writing between the humanist who might sympathize with what you say and the biologist who would not. Piaget considered intelligence to be the psychological analogue of adaptation in biology. He is the researcher who did what is often considered his best work studying intelligence in pre-verbal infants, for whom intelligence, at least according to Piaget, is entirely embodied in sensori-motor schemes.

Piaget railed against logicians who wrote about intelligence for ignoring biology. There is no doubt that he would make precisely the same criticism of Professor Robinson.
