Epilogue

We would like to end this volume of reflections on and appreciation for Joseph Lichtenberg's seminal—indeed, already classic—contribution, Psychoanalysis and Motivation, with an expression of our own personal gratitude to all of the contributors who have so generously responded to our invitation to join in this dialogue with the author. We would also, at this point, like to thank Joe Lichtenberg himself for his Appreciative Response and to restrict our brief closing comments to Lichtenberg's own closing article.

In his article, Lichtenberg not only answers all of the critical and admiring commentaries included in this volume with the same informative and respectful evenhandedness, but he also adds new observations that serve to extend our understanding of the application of his motivational systems. The most frequent concern expressed in these commentaries has been the equal status afforded each motivational system in relation to the others—not only in development, but throughout life, and particularly in the clinical situation. Lichtenberg, to our view, successfully addresses this concern. Gedo's point that the motivational systems as described by Lichtenberg only pertain directly to mode I in Gedo's own developmental schema, with higher form motivations such as morality left unaddressed, is responded to by acknowledging that further attention must be paid to the intricate interrelationship among the motivational systems as development proceeds. Lichtenberg further notes that in his succeeding volume, written in collaboration with Lachmann and Fosshage, as well as in his contribution to a collection by Wilson and Gedo, the motivational systems are further elaborated. Moreover, in Lichtenberg's discussion of our contribution to this volume, he adumbrates two developmental lines—generativity, in the attachment system, and ambition, in the exploratory-assertive system. Lichtenberg's astute and informed observations on the development of generativity and ambition
