I’ve contributed a chapter to this book called Learn to Forget: a Nietzschean Revaluation of Forgetting in Psychotherapy.
The chapter demonstrates the value of cultivating 'active forgetting', and it's use as an intervention in my client work.
In contrast to the gravity and pathology of more mainstream psychoanalytic and psychodynamic ideas about forgetting, active forgetting is lightness; it is integral to happiness, play, possession of power and creativity.
The editor has described the chapter as "Unassumingly formidable."
The book is published by Routledge. Re-visioning Existential Therapy: Counter-traditional Perspectives
