The best ever quote i've seen
"The problem in this day and age, aside from fundamentalist pseudoscience and in reaction to it, is that scientists nowadays want to sell books and become public figures, which means becoming vocal in areas quite outside their own fields of expertise."
"The so-called "New Atheist" phenomenon is a good example of this postmodern, trendy social movement by scientists who seem to make up for lack of any real philosophical sophistication with copious amounts of verbiage."

Since the discovery of Quantum Mechanics in early 20th century, physicists (including several of the founders of QM) were surprised about the ontological implications of it. In short, QM, which is by now the very pillar of our technological society, appears to imply that there is no objective reality that science studies, in the sense that the only way to make sense of the theory is by assuming that reality is contingent on consciousness.
Einstein complained about QM implying that the moon is not there when nobody is looking.
A comment attributed to Niehls Bohr is as follows: "There is no quantum world. There is only an abstract quantum description. It is wrong to think that the task of physics is to find out how nature is.".
Werner Heisenberg wrote: "One cannot go back to the idea of an objective real [material] world whose smallest parts exist objectively."
Pascual Jordan wrote: "Observations not only disturb what has to be measured, they produce it....We ourselves produce the results of measurement."
Eugene Wigner wrote: "It is not possible to formulate the laws of quantum mechanics in a fully consistent way without reference to consciousness...It will remain remarkable in whatever way our future concepts may develop, that the very study of the external world led to the conclusion that the content of consciousness is an ultimate reality."
John Wheeler wrote: "No elementary phenomenon is a real phenomenon until it is an observed phenomenon." And "Useful as it is under everyday circumstances o say that the world exists 'out there' independent of us, that view can no longer be upheld. There is strange sense in which this is a 'participatory universe'".
Arthur Eddington: "To put the conclusion crudely - the stuff of the world is 'mind stuff'".
Bernard d'Espagnat: "The doctrine that the world is made up of objects whose existence is independent of human consciousness turns out to be in conflict with quantum mechanics and with facts established by experiment."
David Mermin commenting on Einstein's question: "We now know that the moon is demonstrably not there when nobody looks."
Sir James Jeans: "The universe begins to look more like a great thought than a great machine."
Martin Rees: "The universe exists because we are aware of it." Euan Squires: "Every interpretation of quantum mechanics involves consciousness."
Nick Herbert published an entire book about the ontological implications of QM, "Quantum Reality".
As recently as 2004 Bruce Rosenblum and Fred Kuttner published "Quantum Enigma: Physics Encounters Consciousness".
Other excellent books are "The Ghost in the Atom" edited by Paul Davies, and "Quantum Phyisics - Illusion or Reality" by Alastair Rae.
These are all no-nonsense physicists, and many of them are eminent ones.
So QM represents a real problem for any materialistic understanding of reality. As philosopher Bertrand Russell put it: "It has begun to seem that matter, like the Cheshire Cat, is becoming gradually diaphanous and nothing is left but the grin, caused, presumably, by amusement at those who still think it is there".
So it was with some interest I started reading Stenger's book to see how he dealt with this problem.
I couldn't be more disappointed.
First of all he doesn't make any serious effort to deal with it.
Rather he concentrates on the various New Age gurus who publish pseudoscience, on various paranormal claims (telepathy and the like), on the sensationalist documentary "What the Bleep do We Know?", as well as on physicists Fritjof Capra's "The Tao of Physics" and Amit Goswami's "The Self-Aware Universe".
The latter two books interpret the quantum problem from the point of view of Eastern mysticism, which may or may not be appropriate, but which is irrelevant to the seriousness of the question at hand.
The whole book strikes me as an intent to use a lot of smoke to convince the reader that there isn't really any serious problem to deal with in the first place.
The book contains many errors and misleading statements in its discussion of science.
So for example on page 95 it says "The organs of the human body, including the brain, run on Newtonian mechanics" - which must be news to biochemists and neuroscientists.
On page 103 it says "[Stephen Jay] Gould also insisted that there was no guarantee evolution would always act to produce increasingly complex forms of life with ever-broadening capabilities. However this remains controversial." In fact this isn't controversial but a rather obvious property of Darwinism.
On page 184 it says "There is no wave-particle duality. Photons are just particles". Actually, that photons sometimes display particle-like behavior and sometimes wave-like behavior is an observational fact and one of the fundamental insights of QM.
On page 207 he writes "No one has ever seen a particle moving faster than light nor transmitted information from one point to another superluminally." In fact in 1995 Horst Aichmann and Gunter Nimtz have transmitted Mozart's 40th Symphony as frequency modulated microwaves (i.e. photons) through an 11.4 cm length of barrier at a velocity of 4.7 times higher than light speed, receiving audibly recognizable music.
On page 196 he claims that the "observer" in the Copenhagen interpretation of QM need not be a conscious being but may be any "passive measuring instrument". In fact what constitutes a "measurement" is much debated about and Stenger's claim above is very far from the concensus. Take for example the famous "Schrodinger's cat" thought experiment: The paradox of having a cat in a quantum superposition of being both alive and dead at the same time would not disappear were one to put a video camera inside the cat's box; rather both the cat and the camera would exist in a quantum superposition.
On page 197 he criticizes Bohm's interpretation of QM by pointing out that it offers "nothing new in calculational ability and producing no unique empirical results". But the same goes for all interpretations of QM, so this is hardly grounds for criticizing one of them. On page 206 he writes "The only deterministic quantum theory is that of Bohm". Actually there is only one quantum theory. Bohm's is one out of several naturalistic interpretations of quantum theory, and his is not the only deterministic one, for Everett's so-called "many worlds" interpretation is deterministic too.
On page 228 he approvingly quotes Jacques Monod who wrote: "Chance alone is the source of every innovation, of all creation, in the biosphere. Pure chance, absolutely free but blind is at the very root of the stupendous edifice of evolution."
This may be the personal belief of Monod, but it's not a belief based on science. For even though the theory of evolution allows for "pure chance" it does not require it. Indeed the Darwinian mechanism works just as well using not chance but a deterministic pseudo-random generator. That's why the theory of evolution has not falsified determinism.
Stenger continues by praising those scientists who wrongly hold that the theory of evolution implies Monod's view: "This remains the view of most scientists, but only a few such as Monod, Steven Weinberg, and Richard Dawkins have the courage to say so publicly. And they are castigated for it."
I don't know whether Weinberg and Dawkins share Monod's unscientific view that the theory of evolution implies randomness. Actually I doubt it.
Dawkins has only claimed, correctly, that the universe we observe is just as it would be if evolution was based on blind chance - not that evolution was based on blind chance. Certainly philosopher Daniel Dennett does not share Monod's belief, as he has explicitly spoken against it.
Where things get bizarre is when Stenger tries to do philosophy.
On page 64 Stenger handwaves away a major view about reality called idealism by noting that when one kicks a rock the rock kicks back; of course that would also be the case if idealism is true, so it's not like kicking a rock "refutes" idealism.
On page 66 Stenger informs us that time exists only in the human mind and that time is really a human invention.
On page 73 we are informed that space too is only a human invention. Humanity has "what masquerades as free will", so free will too is presumably a human invention. Even the laws of physics are "human inventions" (page 262).
Amazing how when one assumes that God is just a human invention, a lot of other basic things must follow suit.
On page 211 he claims that materialism is consistent with "commonplace experience". In fact it's very difficult to see how materialism could possibly be consistent with the very fact of experience; it appears Stenger has never heard of the hard problem of consciousness, or perhaps he tries to shove it under the rug too.
A major part in the end of the book is dedicated to the question of whether the claim that God acts specially in creation is compatible with science. He mentions in some detail the ideas of several theologians in this respect but then comments on their ideas with just a few words, such as "Good try." (page 216), as if he wants to give the impression that such ideas are not worth discussing - but if so why describe them in the book in the first place? In this context Stenger quickly becomes self-contradictory:
On page 241 he states that if God played such a special role in the universe then God "should leave observable physical evidence".
But on page 221 he describes how God could violate the laws of physics in a way that this violation would simply not be "detectable to humans".
Not to mention that if this manner of divine action is fundamentally not detectable to humans then it is incoherent to claim that it represents a violation of the laws of physics; after all we know about the laws of physics from what we can detect.
On page 243 he again describes how God could act in the universe: "To have full control over all events God would have to manage the motion of every fundamental particle in the universe in a nanosecond-by nanosecond basis. I suppose, being omnipotent, he could do that."
So God could massively interfere with the universe without science detecting it after all. So what's the problem? That he "gets the impression in his reading that most theologians would not be happy with that solution". So there.
When confronted with one of the few philosophical premises everybody agrees with, namely that from nothing nothing comes, he redefines "nothing" as what has no structure (page 250), but clearly that's not what "nothing" means.
Argumentation by the redefinition of common concepts appears to be a fashionable trend in atheism.
On page 263 we learn that we can view the Earth and humanity as "forms of frozen nothing". As I said, bizarre.
Finally, the carelessness of the book is annoying.
In the foreword written by the well-known Michael Shermer we read that physicist Amit Goswami had said "The material world around us is nothing but possible movements of consciousness. I am choosing moment by moment my experience."
Shermer then informs us that in his monthly column in Scientific American he publicly challenged Goswami to leap out of a twenty-story building and consciously choose the experience of surviving the experiment. Impressive, no?
Only on page 38 of his book Stenger makes explicitly clear that when Goswami says "I" or "you", as in "you make your own reality", he means the "all-pervasive cosmic consciousness" and not some individual human.
So what is one to make of Shermer's huge equivocation in the foreword? Perhaps he did not read the book to which he wrote the foreword?
But then again didn't Stenger read Shermer's foreword he put in his own book? Hardly likely. It's far more likely that they just don't care. It's all about making an impression.
The book does have some merits. Its explanation of some modern scientific concepts, especially in relation with special relativity, is lucid.
It very convincingly criticizes all claims of top-down causality noting that in all such cases computer simulations using only bottom-up causality produce the relevant effects one ascribes to top-down causality.
But on the whole this is very superficial and misleading book.
Any of the books I mention above does a much better job explaining quantum weirdness.

A child on the philosophy-of-science playground...
If you cast your ontological marketplace vote on what the so-called New Atheist movement enthusiastically tells you (which, let us remember, represents a small but vocal group among the general population), skeptics such as Richard Dawkins (biology) and Victor Stenger or Steven Weinberg (physics) have pretty much eradicated the validity of any type of religious or "spiritual" belief.
According to Dawkins, "Darwin chased God out of his old haunts in biology" (which may be news to some distinguished biologists), and supposedly physicists like Stenger "closed the gaps" on theist hopes from the physics angle, in his numerous books and articles.
I guess all hope for mankind's spiritual inklings has been killed...
Or maybe not.
Stenger's Quantum Gods book is a follow-up to his earlier best-selling God: The Failed Hypothesis. The earlier book targeted the Abrahamic (Judeo-Christian-Islamic) religions, and now Stenger goes after so-called New Age spirituality, or what he calls quantum spirituality, where proponents try to use quantum mechanics to justify a wide range of non-empirical beliefs...many of which have paranormal or Eastern philosophy nuances.
The second part of the book tries to tackle what he terms quantum theology, in which QM and chaos theory are called upon to provide a place for God to act in the world without violating any natural laws.
First, the New-Age phenomenon.
Stenger picks some pretty easy targets to critique, and he does so with obvious relish. He examines typical New-Agey "create your own reality" themes from two enormously popular films (i.e., "The Secret" and "What the Bleep Do We Know"), then turns his attention to a few "fringe" physicists espousing New-Age views (Amit Goswami, Fred Alan Wolf, etc.), plus a few other New-Age characters. Stenger's sarcasm is in full force here, targeting the modern phenomenon where the word "quantum" obviously becomes a buzzword for any type of bizarre pop fad an author wants to promote.
Let's go on to a more problematic aspect of Stenger's book, which is expressed in his comments on so-called "quantum theology".
In my opinion, Stenger's arguments on this topic tend to be superficial and largely inadequate dealing with the complex arguments involved, making this section of his book much weaker than when he is attacking various New-Age beliefs.
The problems begin when Stenger turns his focus off of easy targets and broadens his attack on human "spirituality" (for lack of a better term) in general...which, of course, is an irritating topic to any committed "reductionist".
It is one thing to ridicule certain fringe physicists, for example, who are far away from the mainstream of orthodox science.
It is another thing entirely, however, to attack all metaphysical reflection as if Stenger's own dismissive stance is the only intelligent choice.
Simply, there are numerous world-class physicists, biologists and other scientists who do NOT share Stenger's disdain for anything smacking of "spirituality" (or using Stenger's own definition here, of "somethingism" as opposed to "nothingism").
It is difficult to get this point across to avid readers of the pop atheistic literature, who are typically only exposed to very limited segment of reductionist reading material.
And alas for Stenger personally, some of his fellow physicists (with vastly different metaphysics) are more distinguished in their science work than he is. Just for my own curiosity, I browsed to see how many physicist Nobel-Laureates, for example, have publicly espoused plainly "theistic" or more generally some type of "spiritual" worldviews...sure enough, they aren't hard to find.
My point here isn't to play some kind of game of one-upmanship, but merely to remind fans of Stenger's books that his extremely dismissive worldview isn't necessarily shared by some very distinguished scientists...nor necessarily even by other physicists.
What any objective observer of the New Atheist phenomenon should realize is that attempts to somehow link spirituality to a faulty or inferior intellect (common enough in their literature) is laughable. No one should take this kind of caricature seriously.
But my objection against Stenger's black-and-white reductionist pitch to readers goes deeper than merely comparing scientific achievements on various sides of the reductionist debate.
The heart of the problem with dogmatic atheistic views like Stenger's is, it closes off any real inquiry into metaphysical reflection, PERIOD.
The problem for Stenger assuring us physics has (supposedly) undermined this whole "metaphysics" enterprise - "superstitions", I believe, is the common atheist dismissal - is that no such thing is possible, categorically speaking.
As (agnostic) biologist H. Allen Orr observed in an excellent article for New Yorker (The God Project), "What experiment could prove that the universe has no purpose? To suppose that a kind of physics can demolish a kind of metaphysics is to commit what philosophers call a category mistake."
And we've got more problems. Some of Stenger's views are controversial/idiosyncratic to say the least, which many of his readers might not be aware of.
For example, Stenger has an interesting slant on so-called wave/particle duality.
Stenger's take on the subject is that waves do not exist, and physicists have been wrong all these years referring to a wave/particle duality at all.
