That is the new and excellent book by Adam Phillips, in the US available on Kindle only. Here is one bit:
…Freud was discovering that we obscure ourselves from ourselves in our life stories; that that is their function. So we will often find that the most dogmatic thing about Freud as a writer is his skepticism. He is always pointing out his ignorance, without ever needing to boast about it. He is always showing us what our knowing keeps coming up against; what our desire to know might be a desire for.
Psychoanalysis would one day be Freud’s proof that biography is the worst kind of fiction, that biography is what we suffer from; that we need to cure ourselves of the wish for biography, and our belief in it. We should not be substituting the truths of our desire with trumped-up life stories, stories that we publicize.
