Tallis is a brilliant storyteller with sometimes razor sharp insights into intellectual world surrounding St. Sigismund, influences on him and his influences on the world civilization. He is a Viennese aficionado with a flair for dramatic. Also, his book is a treasure trove of unexpected facts about Freud's views and work. The book sheds light on his impossible greatness given that late in life he himself began to recognize that psychoanalysis is more an anthropological construct than a therapeutic method and had foreseen its replacement in psychiatry by psychopharmacology.
For a practicing analyst, he tells surprisingly little about the structure of psychoanalysis and his venturing into biology is pure crap ([1], pp. 290-293) [2]. And, of course, no nonfiction book emanating from the New York publishing milieu can avoid random (and rather incongruous) mentions of Putin and Ukraine.
[1] A convergence of mythologies of unrelated tribes and peoples was convincingly explained by U. Eco (some remember that his day job was in semiotics) without references to epigenetics. Namely, that primeval beliefs are centered on the comparison of external objects with a human body.
[2] Bygren's 1984 observations of intergenerational heart problems after the famine can be easily explained by the fact that, in times of hunger, survival favors people who randomly accumulate bodily fat faster than others. Naturally, in the subsequent generations, this feature increases the prevalence of heart disease.
The application of a similar logic to the descendants of the Holocaust/Shoah survivors is more tenuous. But following the previous example, one may surmise that, among the survivors, the people with an extreme propensity to sense danger fared marginally better. Yet, for their descendants being permanently under stress could cause substantial problems of adaptation.
