Miss Miranda Weston-Smith 10 Green Street Cambridge : Tel: 0223 66618 ; 28 August 1979 anv Uy Aaolev ber, I am writing to you at the suggestion of Francis Crikky whom I saw the other day. Row ald Duncan and I have compiled two volumes of THE ENCYCLOPAEDIA OF IGNORANCE (to the second of which Crick contributed). These books are collections of essays by world-famous scientists on what they DON'T know. The essays attempt to look beyond the horizon of our current knowledge. . ‘ I enclose a leaflet about these books. We are now compiling a third volume. It will focus on our ignorance about the mind and body and in the medical area. I am writing to you now to ask you whether you might be willing to SY consider contributing to this book? Thés volume, like the previous two, is to be published by the Pergamon Press. They will pay contributors $150 for each copgribution. The essays are to be of about three thousand words in length. We hope to go to press on 1 March 1979. I shall be in New York from 17-21 September - perhaps I might contact you then ?
