"Discussing the play, John H. Marburger III, President George W. Bush’s science adviser, observes that “in the Copenhagen interpretation of microscopic nature, there are neither waves nor particles”, but then frames his remarks in terms of a non-existent“ underlying stuff ”. He points out that it is not true that matter “sometimes behaves like a wave and sometimes like a particle... The wave is not in the underlying stuff; it is in the spatial pattern of detector clicks... We cannot help but think of the clicks as caused by little localized pieces of stuff that we might as well call particles. This is where the particle language comes from. It does not come from the underlying stuff, but from our psychological predisposition to associate localized phenomena with particles.”
The following is radical, but the mbp calls for radical. As stated in the following paper, with which none of us would disagree: "In short, the scientific study of consciousness is in the embarrassing position of having
no scientific theory of consciousness." And I think we would agree there are
no conclusive philosophical models either. So approach the following with an open mind.

"I reject HFD, the hypothesis that a goal of perception is to match or approximate properties of an objective physical world. Instead I propose the hypothesis of multimode user interfaces (MUI): The conscious percep- tual experiences of an agent are a multimodal user interface between that agent and an objective world. ...
Of course tables, chairs and the moon are just our icons, and exist only in our conscious experiences. But what’s new ? Physicists have long told us that the apparent solidity of a table is an illusion. It is mostly empty space with quarks and leptons darting about. Our perception of a table’s surface approximates the envelope of this activity, and in this sense HFD is correct: There are no objective tables, just objective particles.
The mistake here is analogous to a computer user who admits that file icons on the display are just conventional symbols, not the actual files, but then puts a magnifying glass over an icon, sees its pixels, and concludes that these pixels are the actual file. File icons are indeed composed of pixels, but these pixels are part of the interface, not elements of the file. Similarly, tables are indeed composed of quarks and leptons, but quarks and leptons are part of the MUI, not elements of the objective world. The MUI may be hierarchically organized, but different levels of this hierarchy are part of the MUI, not of the objective world.
Placing subatomic particles in the MUI rather than in the objective world is compatible with quantum theory. Indeed, the Copenhagen inter- pretation of quantum theory asserts that the dynamical properties of such particles have real values only in the act of observation (see, e.g., Albert 1992, Wheeler and Zurek 1983, Zurek 1989). That is, they are part of the observer’s MUI. Quantum physics does not contradict MUI theory. ... [Soupie: see quotation above]
Conscious realism is a non-physicalist monism. What exists in the objective world, independent of my perceptions, is a world of conscious agents, not a world of unconscious particles and fields. Those particles and fields are icons in the MUIs of conscious agents, but are not themselves fundamental denizens of the objective world. Consciousness is fundamen- tal. It is not a latecomer in the evolutionary history of the universe, arising from complex interactions of unconscious matter and fields. Conscious- ness is first; matter and fields depend on it for their very existence. So the terms “matter” and “consciousness” function differently for the conscious realist than they do for the physicalist. For the physicalist, matter and other physical properties are ontologically fundamental; consciousness is derivative, arising from or identified with complex interactions of mat- ter. For the conscious realist, consciousness is ontologically fundamental; matter is derivative, and among the symbols constructed by conscious agents. ...
Exegesis of Kant is notoriously difficult and controversial. The standard interpretation has him claiming, as Strawson (1966, p. 38) puts it, that “reality is supersensible and that we can have no knowledge of it”. We cannot know or describe objects as they are in themselves, the noume- nal objects, we can only know objects as they appear to us, the phenome- nal objects (see also Prichard 1909). This interpretation of Kant precludes any science of the noumenal, for if we cannot describe the noumenal then we cannot build scientific theories of it. Conscious realism, by contrast, offers a scientific theory of the noumenal, viz., a mathematical formula- tion of conscious agents and their dynamical interactions. This difference between Kant and conscious realism is, for the scientist, fundamental. It is the difference between doing science and not doing science. This fun- damental difference also holds for other interpretations of Kant, such as that of Allison (1983).
Many interpretations of Kant have him claiming that the sun and planets, tables and chairs, are not mind-independent, but depend for their existence on our perception. With this claim of Kant, conscious realism and MUI theory agree. Of course many current theorists disagree. For instance, Stroud (2000, p. 196), discussing Kant, says:
It is not easy to accept, or even to understand, this philosophical theory. Accepting it presumably means believing that the sun and the planets and the mountains on earth and everything else that has been here so much longer than we have are nonetheless in some way or other dependent on the possibility of human thought and experience. What we thought was an independent world would turn out on this view not to be fully independent after all. It is difficult, to say the least, to understand a way in which that could be true.
But it is straightforward to understand a way in which that could be true.
There is indeed something that has been here so much longer than we have. But that something is not the sun and the planets and the mountains on earth. It is dynamical systems of interacting conscious agents. The sun and planets and mountains are simply icons of our MUI that we are triggered to construct when we interact with these dynamical systems. The sun you see is a momentary icon, constructed on the fly each time you experience it. Your sun icon does not match or approximate the objective reality that triggers you to construct a sun icon. It is a species-specific adaptation, a quick and dirty guide, not an insight into the objective nature of the world. ...
Another objection notes that there seems to be a difference when I meet an object and when I meet someone else. If I meet an object (or whatever it is, since by the MUI hypothesis, we cannot know), a simplified version of it is created by my super-user interface. If I meet another conscious agent, we both see each other and we both interact together. However, the other conscious agent should be equally inaccessible to me, like the noumenic object. How do we get outside of our epistemic jail, the super-user interface ?
To answer this, consider what you see when you look into a mirror. All you see is skin, hair, eyes, lips. But as you stand there, looking at yourself, you know first hand that the face you see in the mirror shows little of who you really are. It does not show your hopes, fears, beliefs, or desires. It does not show your consciousness. It does not show that you are suffering a migraine or savoring a melody. All you see, and all that the user interfaces of others can see, is literally skin deep. Other people see a face, not the conscious agent that is your deeper reality. They can, of course, infer properties of you as a conscious agent from your facial expressions and your words; a smile and a laugh suggest certain conscious states, a frown and a cry others. Such inferences are the way we avoid an epistemic jail, but all such inferences are unavoidably fallible. When we look at a rock, rather than a face, we get much less information about the conscious agents that triggered us to construct the rock. This is no surprise. The universe is complex, perhaps infinitely so. Thus our user interfaces, with their endogenous limits, necessarily give us less insight into some interactions with that universe, and more into others. When we look at ourselves in the mirror, we see first hand the limitations of our user interface and the presence, behind that interface, of a conscious agent. ...
Second, according to conscious realism it simply is not true that con- sciousness is a latecomer in the history of the universe. Consciousness has always been fundamental, and matter derivative. The picture of an evolving unconscious universe of space-time, matter and fields that, over billions of years, fitfully gives birth first to life, then to consciousness, is false. The great psychological plausibility of this false picture derives from our penchant to commit a reification fallacy, to assume that the icons we create are in fact objects independent of us and fundamental in the uni- verse. We embrace this fallacy because our MUI successfully informs our behavior and has ostensible objectivity, because we construct the icons of our MUI so quickly and efficiently that most of us never discover that we in fact construct them, and because we first commit the fallacy in infancy and are rarely, if ever, encouraged to challenge it. The illusion of object permanence starts by nine months, and does not go easy.
Third, standard evolutionary theory itself undercuts the reification fallacy that underlies HFD. Natural selection prunes perceptual systems that do not usefully guide behavior for survival, but natural selection does not prune perceptual systems because they do not approximate objective reality (see, e.g., Radnitzky and Bartley 1987). The perceptual systems of roaches, we suspect, give little insight into the complexities of objective reality. The same for lice, maggots, nematodes and an endless list of
creatures that thrived long before the first hominoid appeared and will probably endure long after the last expires. Perceptual systems arise without justification from random mutations and, for 99 percent of all species that have sojourned the earth, without justification they have disappeared in extinction. The perceptual icons of a creature must quickly and successfully guide its behavior in its niche, but they need not give truth. The race is to the swift, not to the correct. As Pinker (1997, p. 561) puts it:
We are organisms, not angels, and our minds are organs, not pipelines to the truth. Our minds evolved by natural selection to solve problems that were life-and-death matters to our ancestors, not to commune with correctness. . .
[Multimodal User Interface] theory asserts, instead, that the physical world, the world of space-time, objects, matter and so on, is itself a sensory user interface that is observer-dependent. This might be counter- intuitive to a physicalist, but it is not logically self-contradictory. It can be made mathematically precise, and is consistent with quantum theory.
With these provisos, we can now address the main question of this objection, which is why criteria of efficiency and usefulness should control the user interface. The reason is that, according to conscious realism, there is a reality independent of any particular observer, and to interact intelligently or appropriately with that reality one’s sensory perceptions must be a useful and efficient guide to that reality.
Conscious realism is not solipsism. There is a reality independent of my perceptions, and my perceptions must be a useful guide to that reality. This reality consists of dynamical systems of conscious agents, not dynamical systems of unconscious matter. Moreover, this reality is quite complex. So if my sensory systems are to be efficient, they must dramatically simplify this complexity, and yet still provide a useful guide. ...
Nobody explains everything. If you want to solve the mind-body prob- lem you can take the physical as given and explain the genesis of conscious experience, or take conscious experience as given and explain the gene- sis of the physical. Explaining the genesis of conscious experience from the physical has proved, so far, intractable. Explaining the genesis of the physical from conscious experience has proved quite feasible. This is good news: We do not need a mutation that endows a new conceptual appa- ratus to transform the mind-body problem from a mystery to a routine scientific subject, we just need a change in the direction in which we seek an explanation. We can start with a mathematically precise theory of conscious agents and their interactions. We can, according to the norms of methodological naturalism, devise and test theories of how conscious agents construct physical objects and their properties, even space and time themselves. In the process we need relinquish no method or result of physicalist science, but instead we aim to exhibit each such result as a special case in a more comprehensive, conscious realist, framework."
This approach will be unpalatable to many because of its rejection of (1) human perception as faithful description, and (2) physicalism.
The intuition that human perception is priviledged and gives us a faithful description of what-is is a product of anthropocentrism but also an assumption about evolution. We incorrectly assume that evolution favors perception that is faithful to what-is, but it turns out that a faithful description of what-is is not most adaptive.
In short, though it runs against our intuitions and assumptions, there are good reasons to question the HFD.
There are many good reasons to question physicalism as well, obviously the problem of consciousness being exhibit A.
