Both Perelman's collaborators, Professors Haarscher and Ingber, shared with me their deep personal insights about origins, birth and phases of the develop ment of the New Rhetoric. Without their good will, advice and creative com ments, my personal knowledge would have been narrower. I am grateful to the Chaim Perelman Foundation for their grant which enabled me to cover my expenses of collecting materials, editing and preparing the manuscript. Professor Michel Meyer was very instrumental in the negotiations with the publisher. Mr. Raphael Lipski, treasurer of the Perelman Foundation, spent many hours with me, and shared his remembrances of Perelman's personality, his social and political activity. lowe special thanks to Dr. Richard Kramer, whose friendship I cherish for a quarter of a century. He read and edited not only the entire text of the book, but he offered many critical remarks and constructive suggestions which helped me to revise my own ideas and to formulate them more clearly and precisely. The first critical reader and editor was as usual Mrs. Elizabeth Previti. Professor Elzbieta Ettinger-Chodakowska, MIT, read this entire manuscript and shared with me her impressions. lowe special gratitude to my dear friend, Mrs. Stephanie Silvers for her steady help and moral support. Needless to say, I am solely responsible for all the deficiencies of this book.weiterlesen
