Barresi & Moore's “intentional schema” will not do the work of “theory of mind.” Their model will account neither for fundamental facts of social competence, such as the social attributions of the 10-month-old infant, nor the possibility that, though having a theory of mind, the chimpanzee's theory is “weaker” than the human's.

We suggest that innatism and constructivism may differ only in their time scale.

The present intractability of and near intractability of make self-control a difficult topic.
