I would like to thank Judy Gammelgaard and Andrew Moskowitz for their encouragement, critique, and confidence in me, without which I could not have undertaken the present study. I also wish to thank Jon Frederickson for his generous editorial suggestions, and for his writings, which stimulated my interest in the ego in the first place. Last but not least, I want to thank my friend Joachim Meier for our tireless discussions on subjectivity—a continual source of vitality and inspiration during the years of this book’s conception.
