Dear Mrs. Taylor Of course I recall our telephone conversation. I am already moderately well acquainted with de Chardin, having read a couple of his works, and started a comprehensive biography by Cuenot. I was first introduced to the noosphere by Julian Huxley ("The Humanist Frame") and owe a good deal of my philosophical outlook to him and to JBS Haldane. This is not to say, of course, that I have no differences with any of them! Thank you for the book, and for your comment. Sincerely Joshua Lederberg
