with which she invested my weekly supervision hours. Her origi-
nality provided an important bridge to my second source --
namely, the work of those non-aligned members of the Object-
Relations School referred to, in England, as the 'Middle Group'.
The clinical seminars given by Dr D. W. Winnicott during the last
two years of his life ( 1969-70) remain an unforgettable experi-
ence.

The members of Staff at Uxbridge Child Guidance Clinic, par-
ticularly Dr Ronald Urquhart, provided me with a supportive
and enthusiastic setting to pursue my clinical experience with
young children. I would like to thank the staff and the children
who attended the clinic between the years 1969 and 1972.

My thoughts return to an artist, Mr Robert Stewart, Head of
the Department of Design at the Glasgow School of Art, for his
interest in my art work and his friendship during the embryonic
stages of my writing career.

Many friends have read parts of the ms. My thanks go, first, to
my husband, Nicholas Tufnell, who has read numerous versions
of the manuscript; he has listened to me, discussed and teased out
many of the fundamental ideas in this book. He has provided
clarification at all levels from the theoretical to the grammatical. I
wish to thank Mr Jeffrey Steingarten and Ms Caron Smith for
their reading and editing of early versions of the manuscript. For
the completion of the final ms., I am indebted to Mr Peter Mezan,
who came out to California for ten days to help me organise the
manuscript into its final form. His insistence on coherence and
precision revived both the book and the author. I wish to thank
Professor Herbert Morris and Professor Louis Breger for their
careful appraisal of the final edition.

David Godwin of Routledge has been untiring in his support
of this project. Without his continuing interest across 6,000 miles
and timely requests for progress reports, completion might have
been postponed. He could not have been more generous with his
attention and editorship of the manuscript. I thank Harry Karnac
and Cesare Sacerdoti for believing in the book and keeping the
first edition available and for reprinting this new edition. I wish
to thank Mrs Evelyn Siegen for her patience and endurance in the
typing and correction of several versions of this ms.

I am grateful to all the children, young people and adults who
have taught me.
