Freud on a Precipice is an exploration of eight likely early-life traumas experienced by Sigmund Freud and an effort to show how their unconscious processing adversely affected the psychoanalytic theory he forged beginning in the late 1890's. Using a new method to decode key narratives in Freud's opus, Langs makes a compelling argument for the probability that Freud was never sure of the identity of his biological father. The book also offers a fresh study of paradigms, paradigm shifts, and archetypes.

Robert Langs argues that death anxiety is neglected - in part, because of treatment failures due to countertransference interferences during treatment. He then discusses the technical issues connected with this, whilst introducing the controversial concept that mental activities are derived from immune system activities.
