This website and its two sister websites could not have been completed without the advice, assistance, contributions of important pages, and unending loving support of my wife Malou.

My thanks to Jill Tarter for her kind assistance in supplying some of the reference materials for this work.

Prof. Stan McDaniel (Department of Philosophy, Sonoma State University), and Daniel Drasin offered valuable critiques and suggestions for the early manuscripts on which this essay is based.

Saul-Paul Sirag offered valuable theoretical discussions and important information from his own library.

My thanks also to all the other contributors to these pages -- scientists, science writers, "experiencers", radio hosts and journalists who interviewed me for their publications and media, and the new deep friends who consistently support this work.
