Once it is appreciated that it is not possible for an all-powerful, all-knowing, all-loving God to exist, the important question arises: What does exist that is closest to, and captures the best of what is in, the traditional conception of God? In this paper I set out to answer that question. The first step that needs to be taken is to sever the God-of-cosmic-power from the God-of-cosmic-value. The first is Einstein’s God, the underlying dynamic unity in the physical universe which physics seeks to depict by means of a true, unified, physical “theory of everything”. Science has already achieved some theoretical knowledge of this God-of-cosmic-power. The second is what is of most value in our human world, and in the world of sentient life more generally. Having cut God in half in this way, our fundamental problem, intellectual and practical, becomes: How can the God-of-cosmic-value (as it is represented on earth at least) exist and best flourish within the God-of-cosmic-power? Or, in other words: How can what is of value associated with human life – and sentient life more generally – exist and best flourish within the physical universe? Clearly acknowledging that this is our fundamental problem, in academic inquiry, and in all that we do, might help what is of value in life to flourish rather better than it does at present.

A philosophical zombie is a being physically indistinguishable from an actual or possible human being, inhabiting a possible world where the physical laws are identical to the laws of the actual world, but which completely lacks consciousness. For zombies, all is dark within, and hence they are, at the most fundamental level, utterly different from us. But, given their definition, this singular fact has no direct implications about the kind of motion, or other physical processes, the zombie will undergo within its own world. Under quite standard physicalist assumptions, such as certain assumptions about the 'initial conditions' of the zombie's world and that of the causal closure of the physical1, a zombie's behaviour, as well as its underlying physical state, should be indistinguishable from the behaviour and physical state of a genuine human being.

The possibility of empirical test is discussed with respect to three issues: (1) What is the ontological relationship between consciousness and the brain/physical world? (2) What physical characteristics are associated with the mind/brain interface? (3) Can consciousness act on the brain independently of any brain process?

It has been widely thought that consciousness has no causal efficacy in the physical world. However, this may be not the case. In this paper, we show that a conscious being can distinguish definite perceptions and their quantum superpositions, while a physical measuring system without consciousness cannot distinguish such nonorthogonal quantum states. The possible existence of this distinct quantum physical effect of consciousness may have interesting implications for the science of consciousness. In particular, it suggests that consciousness is not emergent but a fundamental feature of the universe. This may provide a possible quantum basis for panpsychism.

Most scientists and theorists concerned with the problem of consciousness focus on our consciousness of the physical world (our sensations, feelings, and awareness). In this paper I consider our consciousness of the mental world (our thoughts about thoughts, intentions, wishes, and emotions).The argument is made that these are two distinct forms of consciousness, the evidence for this deriving from studies of autism. Autism is a severe childhood psychiatric condition in which individuals may be conscious of the physical world but not of the mental world. Relevant experimental evidence is described, including some recent neuroimaging studies pointing towards the neural basis of our consciousness of the mental.

Dualist and Reductionist theories of mind disagree about whether or not consciousness can be reduced to a state of or function of the brain. They assume, however, that the contents of consciousness are separate from the external physical world as-perceived. According to the present paper this assumption has no foundation either in everyday experience or in science. Drawing on evidence for perceptual projection in both interoceptive and exteroceptive sense modalities, the case is made that the physical world as-perceived is a construct of perceptual processing and, therefore, part of the contents of consciousness. A finding which requires a Reflexive rather than a Dualist or Reductionist model of how consciousness relates to the brain and the physical world. The physical world as-perceived may, in turn be thought of as a biologically useful model of the world as described by physics. Redrawing the boundaries of consciousness to include the physical world as-perceived undermines the conventional separation of the 'mental' from the physical', and with it the very foundation of the Dualist-Reductionist debate. The alternative Reflexive model departs radically from current conventions, with consequences for many aspects of consciousness theory and research. Some of the consequences which bear on the internal consistency and intuitive plausibility of the model are explored, e.g. the causal sequence in perception, representationalism, a suggested resolution of the Realism versus Idealism debate, and the way manifest differences between physical events as-perceived and other conscious events (images, dreams, etc.) are to be construed. In the present paper I wish to challenge some of our most deeply-rooted assumptions about what consciousness is, by re-examining how consciousness, the human brain, and the surrounding physical world relate to each other.

How can we understand our human world, embedded as it is within the physical universe, in such a way that justice is done to both the richness, meaning and value of human life on the one hand, and what modern science tells us about the physical universe on the other hand? I argue that, in order to solve this problem, we need to see physics as being concerned only with a highly selected aspect of reality – that aspect which determines how events unfold – the causally efficacious aspect. Physics cannot describe the experiential, and if it is extended so that it does so, physical theory would cease to be explanatory. The human world can, however, be understood in terms of a different kind of explanation, which I call “personalistic”. This is not reducible to physical explanation. The world is, in short, riddled with what may be called “double comprehensibility”.

Nicholas Maxwell takes on the ambitious project of explaining, both epistemologically and metaphysically, the physical universe and human existence within it. His vision is appealing; he unites the physical and the personal by means of the concepts of aim and value, which he sees as the keys to explaining traditional physical puzzles. Given the current popularity of theories of goal-oriented dynamical systems in biology and cognitive science, this approach is timely. But a large vision requires firm and nuanced arguments to support it. Here Maxwell's work is weakest; his arguments for contingent mind-body identity and for free will, on which his larger theory depends, are inadequate. The book is valuable both for its comprehensive view of the human condition and its mysteries, and for its demonstration of the difficulties in making such a view coherent.

In order to solve the problem of the monstrous acts that an all-powerful, all-knowing God would daily be performing, we need to sever the God of Power from the God of Value. The former is the underlying dynamic unity in the physical universe, eternal, omnipresent, all-powerful, but an It, and thus not capable of knowing what It does. It can be forgiven the terrible things It does. The latter is what is of most value associated with our human world - or the world of sentient life more generally. Having performed this surgical operation on God, the problem then becomes: How can we put the two halves of God together again? How can our human world, imbued with experiential qualities, consciousness, free will meaning and value, exist and best flourish, embedded as it is in the physical universe? This is our fundamental problem - philosophical, intellectual and practical. It is our fundamental religious problem.
