I am grateful to the students and visiting scholars who have read and commented on various sections of this work at a number of stages of its development. Their criticisms were very helpful and resulted in numerous improvements in what was, in my opinion, a manuscript with many difficulties. I want to express my appreciation to Samantha Spitaletta, from the Office of Publications at Montclair State University, for her contribution to the preparation of the artwork. I also want to express my gratitude to Manuela Gómez for her help in developing this manuscript so as to fit the enlarged outlook of the second edition onto the foundation represented by the first edition. If the result turns out to be successful, no small part of the credit should be given to her; I am alone responsible for the shortcomings that remain. Likewise, I am indebted to Joanne Matkowski, who lavished care on the manuscript through each of its various incarnations.

I am also grateful for permission to reprint my following articles:
