ABSTRACT
I was honored to participate in Psychological Concepts and Dissociative Disorders, a symposium stimulated by the contributions of D. O. Hebb. When I received my invitation, the image of a blue-bound college textbook flashed into my head, Hebb’s Textbook of Psychology. Later that evening, I was able to find it easily although it had been more than 20 years since I had last opened it. The underlined passages remained fresh, original, and yet contemporary. It has traveled well and remained with me long after I shed the accretion of musty books accumulated from years of college, graduate, and medical schools. The same is true for the ideas of D. O. Hebb. They have remained with us and have traveled well.
