This volume proposes a theoretical integration of several major streams
in contemporary psychological theory about adult development and
therapy. It adopts the perspective that there are steps in development
throughout the adult period, and that they are characterized by a union
of the cognitive and affective, the self and the other, and idea with
idea (in second-order collective abstractions). That is, they are at
once postformal in terms of Piaget's theory, sociocultural in terms
ofVygotsky's theory, and postmodern- with the latter perspective
providing an integrating theme. The affirmative, multivoiced,
contextual, relational, other-sensitive side ofpostmodernism is
emphasized. Levinas's philosophy of responsibility for the other is seen
as congruent with this ethos. The neopiagetian model of development on
which the current ap- proach is based proposes that the last stage in
development concerns collective intelligence, or postmodern, postformal
thought. Kegan (1994) has attempted independently to describe adult
development from the same perspective. His work on the development of
the postmodern mind of the adult is groundbreaking and impressive in its
depth. However, I ana- lyze the limitations as well as the contributions
of his approach, under- scoring the advantages of my particular model.
