"The primary relationship between the infant and the care-giver influences the development of curiosity, the ability to use it productively for thinking and for building the internal world. Curiosity, in its schizoparanoid forms, is an attempt at freezing states of primary undifferentiatedness. In its more mature forms, it serves as an integrative agent and signifies both the possibility and the need to know, as well as the boundaries of knowledge. It is an essential element in the individual's psychic fabric and counterbalances splitting and projective identification."
