Excerpt from Lectures on Psychical Research: Incorporating the Perrott Lectures Given in Cambridge University in 1959 and 1960 This book came to be written because Trinity College, Cambridge, the trustees of the Perrott Bequest for the furtherance of psychical research, invited me to give, in the Lent term of 1959, a course of lectures in the university on that subject. At my own request I gave a second course in the Lent term of 1960. It is provided in the ordinance governing the Perrott Lectureship that the lecturer shall publish the substance of his lectures, and the present work was written and is now published in fulfilment of that obligation. I thought that I might as well be hanged for a sheep as for a lamb, and so I have taken the opportunity to embody a great deal besides the substance of the twelve lectures delivered in 1959 and 1960. Some of the additional material is ultimately derived from lectures and articles already published, and some of it is concerned with topics which I have not handled before in my published writings. In Section B, and particularly in Chapters VI and IX, I have made use of my Presidential Address of 1958 to the S.P.R., entitled 'Dreaming, and some of its Implications', and my lecture of 1953 to the same society, entitled 'Phantasms of the Living and of the Dead'. The Epilogue is based upon two published lectures, viz. the Foerster Lecture, 'Human Personality and the Possibility of Survival', delivered at Berkeley, California, in 1954 and published by the University of California Press, and the Myers Memorial Lecture, 'Personal Identity and Survival', delivered under the auspices of the S.P.R. in 1958 and published by them. I acknowledge with thanks the kind permission granted to me by the S.P.R., and in particular the Trustees of the Myers Memorial Fund, and by the University of California Press, respectively, to incorporate the substance of these lectures in my book. I am under a continuous obligation to the Proceedings and the Journal of the S.P.R., as the main source of the materials of almost every chapter. Then, again, I have to thank the American S.P.R. for kind permission to incorporate in Chapter XI a lecture, entitled 'The Phenomenology of Mrs Leonard's Mediumship', delivered to that society in New York in June 1954 and afterwards published in their Journal.
