This is an opportunity, but also a challenge, to write about books, especially at a time when the pre-eminence of books as the source and repository of knowledge is no longer indisputable. It is, of course, an impossible task to select merely ten books with the implication that these ten have been the most influential in my professional career, which is the same thing as saying that they have been the most influential books in my life. I have selected ten books from literature, philosophy and psychiatry, and these books, drawn from all my main interests, serve as the springboard for discussing other books. There is no principle underlying the order in which the books are discussed. In many respects, the order has been dictated by the internal logic of this essay.
