The two cornerstones on which the whole structure of Freud’s metapsychology rests are, on the one hand, the the- ory of dreams and, on the other, the theory of child development—that is, the ontogenesis of the mind from childhood to adulthood. Children’s Dreams, by Claudio Colace, combines these two cornerstones and adds to them, buttressing the founda- tions with some rigorous empirical, methodological, and epistemological research.
