This is the final book of Huxley's essays, covering the last part of his life. It includes material that is otherwise found in his book Brave New World Revisited. As is the case in all these volumes, the topics addressed are all over the place, from world politics to literature to music to architecture, and any other permutation of the topics you might find in a literary salon of the period.
I've read these half dozen volumes over the course of something like 12 years, so my memory is by no means perfect. I will say that they look nice sitting on the shelf together, but in terms of the actual value of enterprise, I'm not sure how sold I really am. Huxley is a clever writer, and the essays, while you are reading them, are often entertaining. But do these really stand the test of time, and deserve to be read en mass, more than 50 years after Huxley's death? For most of us, the answer is no, unless you develop the weird kind of fascination with Huxley that I have.
Huxley is very much in his gullible, experimental period here, and many of the essays profess an undue openness to concepts like ESP, and a belief that serious scholarship will soon find the phenomenon undeniable. History has not exactly been on his side, here.
I will say this though: this book does have a great essay that has Huxley imagining his personal library burning down, and then having to choose which books to re-purchase. It sure struck a chord with me, and is Huxley at his most entertaining, while also offering penetrating insight into some of his literary tastes, and casting shade on some of his contemporaries.
Throughout the series, I'd have liked more input from the editors, as well. In this volume, we do get an introductory essay, but all the rest of the material is allowed to stand on its own, with no commentary on any of the pieces about Huxley's progression of thought or the importance of any particular piece.
I'm not exactly sure who the audience for this review is, since if you are seeking out these books, you surely know exactly what you're getting. But I am compelled to add my two cents, and now I have.
