Acknowledgments
I began writing this book during the academic year 1980 - 1981 while
I was on leave from Wellesley College and a Visiting Scholar at Harvard
University . Many people have helped me get from the first draft to
the book you now have before you .
Roger Brown , Patricia Kitcher , Richard Lerner , John Macnamara , and
James Moor read the earliest draft and gave valuable guidance .
David Pillemer , Jerry Samet , Kathryn Tolbert , and Ken Winkier gave
sage advice on parts of later drafts.
Howard Gardner , Michel Grimaud , Robert Simon , Barbara Von
Eckardt , Sheldon White , and Jeremy Wolfe read the next to penultimate
version and made many helpful suggestions .
Jonathan Adler and Joyce Walworth provided constant support and
thoughtful criticism . The two of them performed every service from
helping me get my arguments in shape to reuniting split infinitives . I
owe them my deepest thanks.
Karen Olson and Susan Sawyer helped with the bibliography , and
Harry and Betty Stanton , my editors , helped make what ' was already
an intellectually and personally exciting process even more so.
In addition to my gratitude to Wellesley College for supporting the
leave during which the book was first conceived and to Harvard University
for housing me during that year , I owe thanks to many colleagues
at the Center for Advanced Study in the Behavioral Sciencesat Stanford
University , where I spent the summer of 1979 working out several of
the ideas on the connection ~ etween moral philosophy and moral psychology
which appear in this book. Thanks also to many colleagues
who participated in Jerry Fodor ' s Institute on " Psychology and the
Philosophy of Mind " at the University of Washington in Seattle during
the summer of 1981 for helping shape my thinking on some of the
philosophical issuesin cognitive psychology and artificial intelligence .
I am grateful to the Council for Philosophical Studies , the National
Endowment for the Humanities , and the Mellon Foundation for various
research grants which helped to support this project . Last but not least ,

Preface to the Second Edition
I was very gratified by the reception to the first edition of TheScience
of the Mind . By the time of the fifth printing , it became clear that a
second edition should be produced to keep readers abreast of some
recent developments in mind science. The original discussion of AI
was outdated becauseof new work in connectionism and parallel distributed
processing . Chapter 6 has been substantially revised to reflect
these exciting new developments , and minor revisions have
been made in all the other chapters . The other major change involves
the addition of the new chapter " Consciousness. " This chapter reflects
my most recent thinking about this the hardest problem in the
scienceof the mind . I taught a seminar on consciousnessin the spring
of 1989 and had as visitors Dan Dennett , Mike Gazzaniga , Pat
Kitcher , Carolyn Ristau , Georges Rey , David Rosenthal , and Bob Van
Gulick . I am grateful to them for inspiring me to give the problem of
consciousnessa stab . Their ideas are reflected in the new chapter at
many points . I am also grateful to the Sloan Foundation for making
these visits possible . Two colleagues from Wellesley ' s psychology department
and fellow members of our cognitive science group , Margery
Lucas and Larry Rosenblum ( now at the University of California
at Riverside ) , and my colleague from philosophy , Ken Winkier , also
participated in the seminar. I thank them and the wonderful group
of students who shared in the excitement . This second edition is dedicated
to the memory of my beloved brother Peter. He enriched my
life and the lives of our entire family beyond description .

Introduction
Psychology , according to the standard fable , severed its connection
with philosophy in 1879 and became a science. Armchair speculation
was abandoned in favor of a rigorous empirical approach to the study
of mind . Metaphysics and epistemology thus remained the harmless
amusements of fundamentally unrealistic minds , while psychologists
got on with studying the real thing .
Fortunately , the separation has not lasted. Thanks in part to the
recent surge of interest in the cognitive sciences , as well as to a trend
toward a more naturalistic style of philosophy , we are seeing the reemergence
of an exciting and fruitful alliance among philosophers ,
psychologists , and mind scientists generally . This book is intended as
a contribution to this renewed alliance. In it I try to sort out the various
ways in which philosophical assumptions appear in , affect , afflict , and
illuminate the scienceof mind . Conversely , I examine the implications
the science of mind has for traditional philosophical concerns.
Some of the philosophical issues I discuss have received their most
vivid formulations and have taken their most surprising turns within
psychological theories , such as the problem of self - knowledge in psychoanalysis
and the problem of the unity of consciousnessin cognitive
psychology . Other traditional philosophical questions have been declared
solved or dissolved by psychological theories , such asthe problem
of free will in behaviorism , the question of the incorrigibility of introspection
in cognitive psychology , and the mind - body problem in
artificial intelligence . My overall goal is to bring out the way philo -
sophical concerns figure within psychology and to indicate the contribution
psychology makes to the solutions of some reputedly
unsolvable philosophical conundrums .
I think of science , especially the human science , as having a narrative
structure. I mean this in two senses. First , individual theories of mind
are often fruitfully read as stories about what the mind is or would be
like if certain assumptions about it proved to be true. Second , the
histories of psychology and philosophy of mind , taken together , com -

xiv Introduction
prise a series of chapters among which there is intelligible interplay
between earlier and later chapters . Furthermore , the narrative , taken
asa whole or in terms of its major episodes , involves all sorts of drama.
There are the tragic theoretical flaws originating in unarticulated but
seemingly noble philosophical assumptions ; there are moments when
theoretical singlemindedness born of shallow but honest commitment
to a vision pays great dividends ; there are the " reinventions of the
question
ably great thinkers .
My views on the narrative structure of scienceand my abiding conviction
that there is much to be learned from great thinkers , even if
their theories are now considered wrong or outdated , help explain
the structure of this book . I examine critically the ways in which important
philosophical issues arise within several distinct theoretical
traditions . I find it most useful to organize discussion around the
views of some major figure , and have done so in all but three cases.
Within the fields of cognitive scienceand Artificial Intelligence there
are no agreed - upon single representatives . And no one has emerged
to provide " the one true theory " of consciousness. Overall , the cast
of characters includes Rene Descartes , William James , Sigmund
Freud , B. F. Skinner , Jean Piaget , Lawrence Kohlberg , a mixed lot of
philosophers of mind , cognitive psychologists and members of the
artificial intelligentsia , and one evolutionary biologist , E. O . Wilson .
I will have succeeded by my own lights if I provide an account of
the scienceof the mind that indicates just how philosophically rich its
theories are and an account of the philosophy of mind that locates
many of its main problems and concerns in the actual theorizing of
mind scientists . For the reader, going through the book sequentially is
the best strategy , but I have tried to make each chapter stand more or
less on its own so that the book can be read in any order without a
major loss to the overall project . In order to assist the uninitiated , I
have listed several useful introductions to the material under discussion
at the foot of the first page of each chapter , and I have included a list
of suggestedreadings at the end of each chapter .
