Surveying the disparate expert "literatures," which normally take no account of each other, Kegan brings them together to reveal, for the first time, what these many demands have in common. Our frequent frustration in trying to meet these complex and often conflicting claims results, he shows us, from a mismatch between the way we ordinarily know the world and the way we are unwittingly expected to understand it. In Over Our Heads provides us entirely fresh perspectives on a number of cultural controversies - the "abstinence vs. safe sex" debate, the diversity movement, communication across genders, the meaning of postmodernism. What emerges in these pages is a theory of evolving ways of knowing that allows us to view adult development much as we view child development, as an open-ended process born of the dynamic interaction of cultural demands and emerging mental capabilities.
