Acknowledgments
My work owes a great deal to the late Sir Anthony Par-sons; without his encouragement and advice, this book would not have been written. I would like to thank Dr. Ian Netton who spared no effort to assist me in accomplishing my research. Dr. Youssef Choueiri also helped me tremendously in the research for this book. My thanks go to Professor James Maurice for his kind help and understand-ing.
I would also like to express my gratitude to the Department of Arabic and Islamic Studies, particularly Angela Bolton, as well as the library staff, especially Paul Auchterlonie, for helping me during the years of my study.
Special thanks go to Professor Amir Harrak, Uni-versity of Toronto, with whom I had many and very fruitful discus-sions, and for encouraging me to bring this to frui-tion.
Last but not least, I would like to thank my wife Nany for her care and for my younger son Cal for his care of the whole family during the years of my illness.
