In Going Sane, Adam Phillips skilfully marshals a wide cast from literature and the literature of psychology in order to examine the many headed and currently vague notion of sanity.
How is the term used? Why is the term used? Does sanity encompass madness or exclude it?
Opening with a sceptical voice, he considers ideas such as the misuse of the word by The Party in Orwell's 1984 and Laing's consideration of madness as a rational response to circumstances.
Further on, we're challenged to regard the difficulties of an idea of sane sex and the programmed madness of adolescence.
As the book progresses, Phillips asserts his own voice more strongly, finishing with his idea of a sane life; perhaps how a life might be sane, but at least in how the thing might be recognised.
Even while arguing forcefully and eloquently, Phillips still manages to avoid being over prescriptive; his voice is too secular for that. In any case, he insists (in the introduction) that his ideas are there as a challenge.
If you're up for such a challenge and especially if you're interested in where psychology meets philosophy, then this book is for you.
