101 Defenses: How the Mind Shields Itself

Blackman opens the preface with a story from his early days as a doctor: Steve, 26, on hormone replacement after pituitary surgery, says he needs testosterone injections to have sex with his wife — then admits he needs none with his mistress. Years later the author understood what had happened: Steve was using defences such as lying, rationalisation and treating the problem as purely medical. The opening captures the spirit of the book: theory explained through vivid clinical moments.

The preface shows that recognising defences is useful beyond therapy: noticing a teenager's minimisation of danger helps a parent, understanding a rival's grandiosity helps a manager, confronting denial and rationalisation helps the family of someone with a drinking problem. He also warns that pointing out defences to the wrong person or at the wrong moment can do more harm than good. That balanced tone earns the book trust.

The introduction's most memorable part is the electrical-circuit analogy. A defence is like a circuit breaker that trips automatically when feeling surges. In schizophrenia the bulb itself is faulty; in borderline personality the wiring is weak and shorts out under small loads; in neurosis an old breaker brought over from another circuit years ago still trips though it is no longer needed. The therapist's job is to identify which kind of problem the circuit has. The image makes a complex point of psychoanalytic diagnosis accessible to non-specialists.

Chapter 1 defines defences precisely: mental operations that remove components of unpleasant affect — the thought, the sensation or both — from conscious awareness. Following Charles Brenner, anxiety is «an unpleasant sensation plus the thought that something bad will happen», depressive affect «an unpleasant sensation plus the thought that something bad has happened». Each defence carries a number in parentheses so the reader can look it up in the later catalogue.

The chapter's clinical vignettes — Mrs AB, who discovers her husband hiding marijuana and then completely forgets their planned «hot date», and Mr DB, neglected as a child, who is so enraged by extra coursework that he cannot think — show how defences interweave. In the first case the author finds repression, projective identification, identification with the aggressor and displacement in a single episode of forgetting. It is fascinating, though at times it may look like over-interpretation.

The language is heavy: dense terminology, many citations and literal phrasing in the Turkish translation slow the reading, and there are scanning errors. The book is valuable as a desk reference for professionals; general readers are better off dipping in to look up a particular defence.

• Every defence is numbered and cross-referenced in the text for easy lookup
• Theory is illustrated with real clinical cases (Steve, Mrs AB, Mr DB)
• The electrical-circuit analogy simplifies complex diagnostic distinctions
• Dense terminology and literal translation make for slow reading
