By John Bowlby

From the Preface: I first became interested in Charles Darwin as a personality, and as a scientist and invalid, thirty years ago when I read the new and complete version of his Autohiography, edited by hisgranddaughter, Nora Barlow. In it, amongst much else, he makes brief reference to the chronic ill-health from which he suffered over many years and the nature of which, I knew, hadfor long been a subject of controversy, the major issue being whether his symptoms were caused by an organic illness or were of emotional origin. At the time, I was working on the psychological il-effects that are apt to follow a childhood bereavement and so, when I learned that Darwin's mother had died when he was eight years old, I began to wonder whether that might have played some part in the genesis ofhis troubles. Alittle later, when the medical controversy erupted again, I made a brief contribution raising the issue. Having many other commitments at the time,I was unable to pursue the idea further, though Thoped it might one day be possible…”

From the Preface: “…The book is divided into four parts. At the beginningof the first part, I describe some personal experiences that led me to write it. Taking long walks in tropical forests, studying birds, and planning nature conservation activities, I became excited by the idea of sharing with readers my growing awareness of the links between the fundamental laws of physics and the world we see around us. All my life I have loved exploring the realm of living things, but my professional life has been devoted mostly to research on the fundamental laws. These laws underlie all of science (in a sense that is discussed in this book) but often seem far removed from most experience, including a great deal of experience in the other sciences. Reflecting on questions of simplicity and complexity, we perceive connections that help to link together all the phenomena of nature, from the simplest to the most complex…”

From the editor: In preparing this volume, which is practically an abbre­viation of the Life and Letters (1887), my aim has been to retain as far as possible the personal parts of those volumes. To render this feasible, large numbers of the more purely scientific letters are omitted, or represented by the citation of a few sentences. In certain periods of my father’s life the scientific and the personal elements run a parallel course, rising and falling together in their degree of inter­est. Thus the writing of the Origin of Species, and its publication, appeal equally to the reader who follows my father’s career from interest in the man, and to the natural­ist who desires to know something of this turning point in the history of Biology. This part of the story has there­fore been told with nearly the full amount of available detail.
