The Character of Consciousness
What is consciousness? How does the subjective character of consciousness fit into an objective world? How can there be a science of consciousness? In this sequel to his groundbreaking and controversial The Conscious Mind , David Chalmers develops a unified framework that addresses these questions and many others. Starting with a statement of the "hard problem" of consciousness, Chalmers builds a positive framework for the science of consciousness and a nonreductive vision of the metaphysics of consciousness. He replies to many critics of The Conscious Mind , and then develops a positive theory in new directions. The book includes original accounts of how we think and know about consciousness, of the unity of consciousness, and of how consciousness relates to the external world. Along the way, Chalmers develops many provocative the "consciousness meter", the Garden of Eden as a model of perceptual experience, and The Matrix as a guide to the deepest philosophical problems

David Chalmers' The Conscious Mind was a hard act to follow, even for David Chalmers himself. Thus for those who know Chalmers work already there are no new bombshells in this new collection of essays. Here he responds to critiques of his "Two Dimensional" semantic framework and the zombie argument of the previous book.
The zombie argument goes as follows: It's conceivable in a sense that a life awake human body could be atom for atom identical with mine and yet lack consciousness, perception, sensation, and thought. If it's conceivable, it's metaphysically possible. So materialism is false if materialism is the view that my physical body is completely constitutive of all my mental properties. Of course what sense of conceivable? Well the idea is that if seeming to have sensations like pain comes to the same as having them, and if the activity of c-fibers in the brain exhaust the physical nature of the brain state, then any identity between these two must be a necessary one. It should not be possible certainly for the referents to be different and since the senses and references are the same in these cases, it should not be possible for the senses to differ either. But the senses do differ and do mean different things, pain does not mean the firing of c-fibers nor can their identity be "worked out on paper" the way potentially you could work out other identities like heat=molecular motion or Kepler's laws are a consequence of Newton's laws so the identity is not a necessary one after all.
Chalmers had said in previous work that Russelian monism (neutral monism) was one way out of the zombie argument and that it was a position he favored but would not defend directly. (The other way, of course, is to deny that the appearance of sensations are what they are; they might be eliminable illusions as Dennett has urged in "Quining Qualia".) Russelian monism is an enhanced physicalism where so called intrinsic properties of matter are required to ground the outward causal relations described by physics and accessible through indirect physical measurement by means of those causal relations. Thus every physical event has both an outward relation structurally and causally to other physical events and an inward nature (or quality) accessible only to itself. Clearly if that is true, then the physical zombie is not a genuine physical possibility since any collection of material atoms will possess necessarily an "inward nature" too, on enhanced physicalism. The identity now becomes a so called a posteriori necessity, since one of the terms "c-fibers" is actually non-rigid and does not pin down the internal nature of the physical process. If it did, you would find that indeed the interior of the physical brain process is pain, just as Russellian monism predicts.
Chalmers suggested taking Russellian monism seriously in the philosophy of mind when others simply dismissed the position as crazy (as they still do). This book should bring a lot more attention to the position and those of us who work on it--so who could be against that? As one who thinks the idea is far from crazy, I'm glad to see him stand up for the idea more strongly than he did in the Conscious Mind. He includes it now as an explicit disjunct for those who would like to avoid his zombie argument and the conceivability of zombies. One big yay for Russell!
Just a comment or two: I sometimes feel that although Chalmers has done more than anyone to enliven the discussion of physicalism and the mind body problem, he also hasn't done enough to remove us from the "bad old days" of thought experiments using linguistic arguments from modal logic to decide what is or is not possible in the real world. See his colleague Daniel Stoljar for a critique of a priori argumentation under conditions of ignorance. Modal arguments can tell us about our concepts perhaps but not about whether those concepts represent reality in any metaphysically necessary sense. For that you need science.

Essentially, David Chalmers lays out the best arguments against materialism, which is the belief that only matter exists, and that everything in the universe (including consciousness) can be explained in terms of physical processes. It's definitely not a 'popular philosophy' book. Large parts of it are very detailed indeed, and I found myself skipping whole sections. Nonetheless it is interesting, and Chalmers comes across as a very balanced and objective thinker.

The only book in Anglo-American philosophy that attempts to give an honest and complete account of consciousness. Very thorough and rigorous. Very compelling arguments concerning the metaphysics of consciousness that undermine the conventional materialist accounts. Chalmers is the most important thinker in the field of consciousness studies and this book is the most important book.

Some portions of the book I did read through carefully and others (The Matrix essay) I skipped entirely.
If you have read the conscious mind (1995) by Chalmers, then I would maybe suggest reading this book as it goes through the same issues brought up in the conscious mind and he does differ in opinion on certain aspects of consciousness.
Good read.

Exceptionally clear writing. Paradigmatic way of writing philosophy.

Huge, boring, philosophical book about consciousness. A good start about consciousness as experience and its irreducibility. Then a deep, long dive into philosophical analysis without easy enough to comprehend synthesis. This makes this book really hard to read.

Some of the clearest, most rigorous writing on the metaphysics of consciousness, and philosophy of mind in general - Chalmers is...phenomenal!

Still not convinced that philosophical zombies are conceivable. I can't get over the explanatory gap for how such zombies can perfectly reproduce conscious behavior.

...the structure and dynamics of physical processes yield only more structure and dynamics, so structures and functions are all we can expect these processes to explain. The facts about experience cannot be an automatic consequence of any physical account, as it is conceptually coherent that any given process could exist without experience. Experience may arise from the physical, but it is not explained by the physical.
I appreciated the first five chapters the most. Chalmers defends the existence of the “hard problem” against unsatisfactory attempts to deflate it, develops a taxonomy of possible solutions, and provides commentary on relevant scientific issues. The penultimate chapter, which uses a discussion of The Matrix to provide thoughts on the problem of skepticism in general, is also quite interesting.
I found many of the other chapters difficult to follow, likely because I lack background in the philosophy of language. The connection of the highly technical discussions to the “big picture” was often unclear to me.

Regrettably this book is too heavy on the metaphysics side for casual reading and I took the easy way out as the author suggested. Overall the arguments are well thought out. Where we differ is that where the author believes it’s fundamentally impossible to perform scientific study on what is private and not subject to third person investigation, I have a reductionism conviction, without proof of course, that we can eventually know enough to understand consciousness from elemental physics.
