Humphrey's latest book, a sequel to his 1992 book, A History of the Mind, is based on a series of lectures he gave at Harvard in 2004 to the Mind/Brain/Behavior Initiative Distinguished Lecture Series, and is written in a style intended to re-create as nearly as possible the informal give-and-take of those lectures, in which the audience sat bathed for much of the time in the intense red light reflected from a giant screen behind the lecturer. It is very much Humphrey's purpose to get readers to set aside what they think they know about seeing red and to experience seeing red anew, so they can reflect on their experience and not just on some remembered or imagined episode of seeing red in the past. He is attempting to resurrect and sharpen a suitably hard-to-credit claim made by the brilliant 18th century Scots philosopher Thomas Reid: our mind--our brains--are equipped with two very different and surprisingly independent "provinces," or systems, sensation and perception, and contrary to all appearances, it is not the case that sensation provides the raw material out of which perceptions are then refined...There is no doubt that his methods have already made a large contribution to our understanding of consciousness. In fact, a price he pays for his impressionistic methods is that he influences other thinkers almost subliminally; more than a few theorists have absorbed major elements of his message and then innocently reworked them and presented them as their own pet ideas. If that is a projectible pattern, we can anticipate that this book will be regarded as a somewhat eccentric and dismissible foray by many whose own work will subsequently bear the stamp of his thinking, whether they realize it or not. Among philosophers, unwitting reinvention rivals denunciation as candidates for the sincerest form of flattery, and by those measures, Humphrey has had more than his share of deserved accolades.

Since [the late 1960s], Humphrey has written extensively and insightfully about consciousness. His most recent work, a slim and elegant volume entitled Seeing Red, provides a charming, if brief, summary of his current views, blending themes culled from psychology, philosophy, and even art and poetry. It also offers intriguing speculations on the evolutionary function of consciousness...The strength of Humphrey's book lies in its skilful blending of ideas from varied sources to stimulate new ways of thinking about consciousness. In effectively doing so, while presenting a fascinating window on the thought of a distinguished consciousness researcher, Seeing Red is a wonderful success.
Illustrating his argument with the musings of poets and painters, Humphrey stylishly inspires curiosity about consciousness.
There are few scientists who think so originally, provoke so consistently or write so elegantly as Humphrey. Seeing Red...is a wonderful introduction to his iconoclastic thinking...Seeing Red is less about what consciousness is than about how we might go about thinking about it. And for that there are few better guides than Nicholas Humphrey.
It's a delight to read, beautifully clear and concise, while packing lots of good sense...[An] intellectual tour de force...Few contemporary writings on consciousness achieve half as much.

If ever the phrase "in our end is our beginning" applied appositely, it does so here. The benign circle of Nicholas Humphrey's argument is that the explanation of why and how we have conscious experience, phenomenal consciousness, is also the explanation of why we find it so hard to understand why and how we can have it--to the point where some think such understanding unattainable. It is a very neat argument. Once we start reflecting on why we might find an understanding of phenomenal consciousness so elusive, we have taken a major step towards understanding it--what it is, what it does, and why it evolved. In Seeing Red, much argument lies between Humphrey's description of our initial bafflement about sensations or "qualia"--i.e., the phenomenon of there being 'something it is like' to experience, say, red--and his rather brilliant explanation. The argument accessibly interweaves empirical research and philosophical analysis, to produce a most important little book.
Harvard Book Review
[Seeing Red is] a collection of small and unexpectedly lucid thought experiments on a topic that has universal appeal...Humphrey provides a refreshing take on this ancient topic...One of the key merits of Seeing Red is its multi-disciplinary approach to defining something that has eluded definition for centuries. Humphrey draws upon philosophy, art, and psychology in turn, producing a holistic narrative that almost seems a microcosm of human experience. And this is part of Humphrey's particular gift: he demonstrates a poetic understanding of the human psyche, its desires and insecurities...[This is] a book that is, above all, written for the sake of asking questions rather than answering them.
South China Morning Post
Humphrey has published several graceful philosophical works on consciousness, but none as intimate or compelling as Seeing Red...His sensitivity and intellectual probity make for magnificent debate. Seeing Red is a book to be savoured--ruminative, fluent and daring to the end.
Times Higher Education Supplement
I like short books. Better still, I like short books so packed with ideas that I have to stop and think on every page. Seeing Red is that sort of book...In Seeing Red Humphrey brings together all his previous research and theorising to give us a counterintuitive and distinctly uncomfortable way of thinking about the nature of seeing...A book that makes me think so hard, in just 150 pages, is one I must recommend.
Journal of Consciousness Studies
"Consciousness is a fascinating but elusive phenomenon; it is impossible to specify what it is, what it does, or why it evolved. Nothing worth reading has ever been written about it," so wrote Stuart Sutherland that stalwart defender of scientific purity...In this delightful little book, Nicholas Humphrey turns the tables by arguing that fascination and elusiveness is the whole point of consciousness...The book is based on a series of lectures Humphrey gave at Harvard in 2004, and has been meticulously edited and updated. It's short--in fact can be read at one sitting--but packs a lot in...The story is both appealing and valuable.
Why are we conscious in the subjective way we are, when other creatures get along perfectly well without this particular capacity?...Seeing Red tackles this task with a directness and dignity seemingly not often achieved in current technical writing...The book is completely engaging and comfortably authoritative. Humphrey draws on decades of study and reflection on mind, self, and consciousness. Readers of his earlier works will recognize Humphrey's insightful premises, and will be yet again impressed with the robustness of his positions and ideas.
Seeing Red is a brilliantly inventive account of the evolution of consciousness, the best yet.
