A Heap of Consciousness



Ira brought up his concept at our recent Philo Club meeting, which he claims he shares with Einstein and Spinoza, that the sum of many consciousnesses is another super consciousness. He uses the fact that the sum of a multitude of neurons constituting the entire brain add up to a consciousness as a proof by analogy.

The trouble with this approach is that it produces the "Problem of the Heap." If there is a heap of grains and one grain is subtracted, does one still have a heap? If the answer is yes, and one keeps subtracting grains, at what point does one cease to have a heap? If one assumes there is a super consciousness, and one subtracts individuals, at what point does the super consciousness disappear? Both problems are born in the concept of vagueness. A heap is a vague concept and so is consciousness.

Einstein's Cosmological Philosophy

[Presentation to Philosophy Club, The Villages, FL, 17 Dec 2010. Download the PowerPoint charts here]

Do I have any special qualifications for giving this presentation? Well, both he and I ride bicycles, and, Einstein in German means "One Stone" while mine (German spelling: Glücksstein) means "Lucky Stone" :^).

My main source is Walter Isaacson's excellent 2007 book, Einstein, His Life and Universe. I also used Einstein's own The World as I see It (1949) and Out of My Later Years (1950), and a number of online sources including Wikipedia Einstein and Cosmology, Wikiquote, Marxists.org, and Einstein's 1427 page FBI FOIA file.

POLITICS: Was Einstein a Socialist?

Let us get this out of the way at the outset. Yes, he was a socialist. In Why Socialism? (1949) he wrote "I am convinced there is only one way to eliminate these grave evils [of capitalism], namely through the establishment of a socialist economy, … the means of production are owned by society itself and are utilized in a planned fashion. … guarantee a livelihood to every man, woman, and child. …”

However, in that same article, he cautioned "The achievement of socialism requires the solution of some extremely difficult socio-political problems: how is it possible, in view of the far-reaching centralization of political and economic power, to prevent bureaucracy from becoming all-powerful and overweening? How can the rights of the individual be protected and therewith a democratic counterweight to the power of bureaucracy be assured?"
His FBI FOIA file concludes that he "was a member, sponsor, or affiliated with thirty-four communist fronts between 1937 and 1954." IMHO the FBI was justified in denying Einstein access to classified A-Bomb information and investigating him for possible disloyalty.

Although the FBI did not discover it while he was alive, letters that became public in 1998 prove that Einstein had an affair with a Soviet spy, Margarita Konenkova, from 1941 until 1945. [Image added 24 December 2010, from Filosophando, click for larger version.]

If Einstein was alive today, I believe he would have realized, based on the subsequent history of Communism (Russia, China, ...) that his cautionary words, quoted above, were more valid than he thought they were when he uttered them in 1949. However, I also believe he would be a "social justice" western liberal/progressive and definitely not in tune with my politics.

SCIENCE: His Great Contributions
His first published paper, on the capillary forces of a straw (1901), and his second, on the thermodynamic equivalence of heat, work or particles (1902) were a non-distinguished prelude to his four amazingly breakthrough miracle year publications in 1905:


  • The Photoelectric Effect (showing that light was composed of quanta rather than continuous waves, and which later led to the wave/particle duality of quantum mechanics, and for which he won a Nobel in 1921),


  • Brownian Motion (kinetic theory of heat),


  • The Special Theory of Relativity (that uniform motion is indistinguishable from rest, and the speed of light is the same for moving or stationary observers), and,


  • The Equivalence of Mass and Energy (e = mc², and, since c, the speed of light in a vacuum is such a large number, and when you square it, it is much, much larger, a tiny abount of mass, m, is equivalent to a tremendous amount of energy, e, witness the Atom bomb)


Between 1907 and 1911 Einstein considered the equivalence of gravity and acceleration. He reasoned that a person in a closed box on Earth would, of course, experience normal gravity. However, if the closed box were transported to space, out of the influence of any nearby mass, and then accelerated to 32 ft per second squared, the person would feel the exact same effects as those of gravity on Earth.

In 1915 he published his General Theory of Relativity, showing that matter causes space-time to curve, which we experience as gravity. He predicted that the gravity of the Sun would cause the light from a star to appear to curve and this was confirmed by Eddington, during an eclipse of the Sun in 1929.

The presentation includes animated Powerpoint charts for:



  • Relativity and Speed of Light (A bullet fired from a Gun on a moving train goes faster than from a stationary vehicle, yet a light beam fired from a Laser on a moving rocket does not go faster than from a stationary vehicle), and
  • Einstein's Cosmology (Static, Oscillating, and Expanding Universes, as well as speculation on how Black Holes, predicted by Einstein in 1915, may, via Continuous Creation be the key to something like his Eternal Universe)


COSMOLOGY: Blunders or (Yet Unrecognized) Genius?
Einstein had certain strong expectations of Nature and the Universe (which, see below, he regarded as equivalent to Spinoza's God as well as his own). That led him to expect that the Universe would be static, neither expanding nor contracting, so it could be Eternal in some sense. So, in 1917, he included the Cosmological Constant (Λ) to counteract gravity. When Hubble showed that the Universe was expanding (1929), Einstein said the Cosmological Constant was his "biggest blunder" and, in that same year, adopted what is called the Friedman-Einstein oscilating Universe, which is Eternal in that the mass/energy is constant. When that became untenable, in 1932, he adopted what is called the Einstein-de Sitter Universe, which expands forever, but the rate of expansion slows down over time.

Current accepted truth is that the Universe not only expands forever, but the rate of expansion is increasing, not slowing down. (OY!) And that the Universe had a beginning in the Big Bang (OY! OY!) and it will have an end as the density of mass/energy approaches zero due to the accelerating expansion, and entropy goes to maximum (OY OY! OY!) In my presentation, I speculate (along with Fred Hoyle, Roger Penrose, and others) that black holes and multiple dimensions we cannot sense, may allow an Eternal Universe, with matter/energy continually recycled between the dimensions we can experience and the hidded dimensions, with density and entropy refreshed.

RELIGION: From Moses to Spinoza to Einstein
Young Einstein was the product of a secular family that acknowledge their Judaism. He said "As a child, I received instruction both in the Bible and in the Talmud." So, he knew about Moses and the Rabbis, but, early on, became more enamored of Science and Spinoza. The presentation includes part of his 1920 poem to Spinoza (and in the Notes below the chart, the complete text in English and the original German), and his 1929 statement "I believe in Spinoza's God, Who reveals Himself in the lawful harmony of the world, not in a God Who concerns Himself with the fate and the doings of mankind." For Einstein, God and Nature were one, writing in 1921 "Subtle is the Lord, but malicious He is not. … Nature hides her secret because of her essential loftiness, but not by means of ruse."
His dedication to determinism, in defiance of mainstream physics and the quantum mechanics whose foundation he had personally laid, was based on religious conviction that "God does not play dice with the universe" (1926). He also said, in 1931, "I am compelled to act as if free will existed …[on the other hand, I know] ‘a man can do as he wills, but not will as he wills.’" [quoting Schopenhauer]

He thought scientists needed a type of faith that springs from the religious sphere: "science can only be created by those who are thoroughly imbued with the aspiration toward truth and understanding. This source of feeling, however, springs from the sphere of religion. … the faith … that the regulations [for] the world of existence are … comprehensible to reason. I cannot conceive of a genuine scientist without that profound faith. The situation may be expressed by an image: science without religion is lame, religion without science is blind." (1941) In 1931 he defined three stages of religious belief, going back to his Jewish roots and how they led him to what he considers a higher form of faith: "Jewish scriptures admirably illustrate the development from the religion of [1] fear to [2] moral religion … but there is third state of religious experience … which I will call [3] cosmic religious feeling … which knows no dogma and no God conceived in man’s image".
He used personal terms for God, "Dear God (die Lieber Gott) ... The Old One (der Alte) ... Lord God (Herrgott)", yet he wrote in 1949: "the idea of a personal God is a childlike one. …[but] I do not share the crusading spirit of the professional atheist whose fervor is mostly due to a painful act of liberation from the fetters of religious indoctrination received in youth. I prefer an attitude of humility corresponding to the weakness of our intellectual understanding of Nature and of our own being." and in 1931 "I see a clock, but I cannot envision the clockmaker. The human mind is unable to conceive of the four dimensions, so how can it conceive of a God, before whom a thousand years and a thousand dimensions are as one?"
Perhaps his best advice for scientists, and everyone else, is "Everything should be made as simple as possible, but no simpler." (1950)

THE GOD DELUSION



Unlike Christopher Hitchens's "god is not Great", written from an historical/literary point of view "THE GOD DELUSION", by a respected biologist, contains actual science-based arguments.

Evolution of Memes

Richard Dawkins previously wrote "The Selfish Gene" (1976) where he introduced the word "meme" (from "mimeme" derived from the Greek "mimeisthai" which means "to imitate"). The word "mneme" was used by others in a similar way as early as 1927 (from the Greek mimneskesthai" which means "to remember").

A meme is the cultural equivalent of a gene. Dawkins wrote: "DNA is a self-replicating piece of hardware. Each piece has a particular structure, which is different from rival pieces of DNA. If memes in brains are analogous to genes they must be self-replicating brain structures, actual patterns of neuronal wiring-up that reconstitute themselves in one brain after another."

The etymology of the word "meme" itself is an excellent example of the evolution of the cultural equivalent of genes. “Meme” is one letter shorter than “mneme” and far easier to pronounce. A challenge arose in 1980 when E.O. Wilson introduced a new word, "culturgen" for the same concept. That word has all but died out as “meme” survived and replicated in the natural human selection process. Clearly, the word “meme” is the “fittest” (best fits into the human cultural environment and brain structure).

A Personal God IS a Delusion – But is it a Useful Myth?

Although I agree with Dawkins that the concept of a personal God, external to the Universe, is, strictly speaking, a delusion, I am surprised at the vehemence with which he attacks it. He minimizes the significance of the fact that the various religions which survived and reproduced over millennia and encompassing the belief systems of billions of people are the “fittest” beliefs (best fits into the human cultural environment and brain structure, regardless of whether or not they are literally true). As such, they must have provided some real benefit to believers and the societies that promoted and still cling to religious beliefs.

About half-way through the book, he finally acknowledges, however grudgingly, the facts. He writes [pg 163 …166]:

[W]e should ask what pressure or pressures exerted by natural selection originally favoured the impulse toward religion. … Religion is so wasteful, so extravagant; and Darwinian selection habitually targets and eliminates waste. …no known culture lacks some version of the time-consuming, wealth-consuming,hostility provoking rituals, the anti-factual, counter-productive fantasies of religion.

David Wilson and Group Selection

Dawkins searches, in vain, for rational explanations for the survival of the God delusion. He mentions David Wilson [pg 170] a colleague of Howard’s and one of my favorite professors at Binghamton University who Dawkins rightly calls “the American group-selection apostle”.

Group selection makes the claim that groups, including religious associations, which promote cooperative, altruistic behaviors, survive at the expense of less religious groups. While I accept multi-level selection (gene level and meme level), I am not sure that true, pure altruism exists and have gone round and round discussing this with Wilson.

David Wilson has an annual “Darwin’s birthday” event at his home that my wife and I have attended. He gave me a plastic knock-off that is like a “Jesus fish” but this one has feet and the word “Darwin” on it. He also gave me a copy of his excellent book, Unto Others .

I agree with Dawkins that what appears to be altruism is actually kin selection (favoring those with common genes) or reciprocal altruism (helping others of the same or different species in return for a benefit). In complex human society it is often difficult to know who is kin or who may provide a reciprocal benefit, so we generalize the concept and indoctrinate our children to help all older people, cooperate with all neighbors, and so on. That is an “accidental” side-effect of kin- and reciprocal altruism, but it never-the-less benefits those societies who imprint generalized cooperative behaviors, so long as altruism is not taken too far.

Dawkins ultimately rejects group selection and is left with the only remaining alternative, that religion is an unintended byproduct of something else. What is this “something else”? Well, he concludes [pg 174-176] it is “obey the tribal elders … For excellent reasons related to Darwinian survival, child brains need to trust parents, and elders whom parents tell them to trust.”

Religion as a “Mind Virus”

Religion, Dawkins asserts, is a mind virus that feeds on the need for a child to obey elders without question, just as computer viruses are based on the need for a computer to follow instructions. The implication is that all societies of the past have had the mentality of children. With the advent of the age of reason we have the opportunity to grow up and reject religion once and for all. I find that “logic” kind of haughty and simple-minded.

Perhaps, with the rise of science and modern technology and so on, literal belief in a personal God is no longer as adaptive as it was in the past. In coming centuries, we humans may modify our beliefs to something like what Dawkins calls the “Einsteinian religion”, or the “Gaia” of Lovelace, or some other science-based concept of that unifying thing we all feel that is larger than all of us.

Scientists who Invoke "God" - Is such Belief Genuine Religious Feeling?
Dawkins knocks Stephen Hawking [pg 13] for ending his A Brief History of Time with a reference to God. Hawking wrote:

However, if we discover a complete theory, it should in time be understandable by everyone, not just by a few scientists. Then we shall all, philosophers, scientists and just ordinary people, be able to take part in the discussion of the question of why it is that we and the universe exist. If we find the answer to that, it would be the ultimate triumph of human reason -- for then we should know the mind of God.” [Emphasis added]
Dawkins, quoting only the phrase I have highlighted, criticizes Hawking for being "dramatic (or was it mischievous?)".

Dawkins includes Einstein’s famous references to religion and God [pg 15]:



Science without religion is lame, religion without science is blind.

I believe in Spinoza’s God who reveals himself in the orderly harmony of what exists ….

God is subtle, but not malicious … God does not play dice …
Did God have a choice in creating the Universe?

I am a deeply religious nonbeliever. This is a somewhat new kind of religion.

What I see in Nature [notice uppercase “N”] is a magnificent structure that we can comprehend only very imperfectly, and that must fill a thinking person with a feeling of humility. This is a genuinely religious feeling that has nothing to do with mysticism.”
Is Scientific Pantheism “Intellectual High Treason”?
Dawkins, in a statement worthy of Anne Coulter, dismisses [pg 19] the metaphorical use of the word “God” by scientists as “intellectual high treason” because it deliberately confuses the distinction between the personal God of “supernatural religion” with the Pantheistic God of “Einsteinian religion”.

It is amazing to me that the originator of the idea that memes evolve in a way similar to genes can be so blind to what is happening! Memes evolve by building upon previous memes. The pagan “rebirth of the Sun” winter solstice meme evolved into Christmas when early Christian authorities co-opted that time period for the birth of Jesus, and, later, when Jewish authorities glommed onto that same time period and elevated Chanukah to a higher significance than it originally claimed. Similarly, IMHO, the traditional supernatural God meme is evolving into a more naturalistic Pantheistic meme. Perhaps the Gaia idea that the Earth biosphere has developed some sort of Global Consciousness will ease the transition. Perhaps it is even true!

Dawkins Quotes Carl Sagan:



A religion, old or new, that stressed the magnificence of the Universe [note upper case “U”] as revealed by modern science might be able to draw forth reserves of reverence and awe hardly tapped by the conventional faiths.

Perhaps, when Sagan talks of a new religion, he is describing the naturalistic yet genuine religious beliefs of Hawking and Einstein and Spinoza. It seems to me it is better to believe in something than in nothing. Sagan also wrote:
In many cultures it is customary to answer that God created the universe out of nothing. But this is mere temporizing. If we wish courageously to pursue the question, we must of course ask next where God comes from. And if we decided this to be unanswerable, why not save a step and decide that the origin of the universe is an unanswerable question? Or, if we say that God has always existed, why not save a step and conclude that the universe has always existed. [Emphasis added]

Scientists are in the same boat with religious believers when they conclude the Universe (like the God of literal believers) always existed! Where did all that energy and matter come from? Where did all the wonderful Laws of Nature that scientists struggle to discover come from? Like the religious believers who say that God always existed, and He created the Universe, scientific believers, in Sagan’s words, “save a step” and assume the Universe always existed! The origin of the Universe is, like the origin of God, an unanswerable question.

Bashing the God of the Old Testament

According to Dawkins [pg 31], the OT God is “… jealous and proud of it; a petty , unjust, unforgiving control-freak; a vindictive, bloodthirsty ethnic cleanser; a misogynistic, homophobic, racist, infanticidal, genocidal, filicidal, pestilential, megalomaniacal, sadomasochistic, capriciously malevolent bully.”

Mischaracterizing Intelligent Design

Dawkins mentions intelligent design (which he calls “creationism in a cheap tuxedo”) on nine pages of this book, but he does not appear to understand it. Intelligent design proponents claim the origin of life on Earth by purely random processes is highly improbable and therefore conclude the initial biological cells were planted here on Earth by some extraterrestrial designer. After that, some of them accept the scientific explanation that something like evolution and natural selection took over and resulted in the wide variety of species on Earth. That theory, per se, is certainly possible. Life on Earth may have been planted by some visiting alien life form. Of course, this raises the question of the origin of the alien life forms.

I, like Dawkins, believe life originated on Earth through un-directed mixing of atoms and molecules. Though highly improbable from a statistical point of view, it seems clear to me that life originated by random chance either here on Earth (or on some other planet in the Universe and was later seeded here).

Dawkins Agrees “Chance is not a solution”

On the positive side, Dawkins [pg 119] realizes that, given those first primitive biological cells, subsequent evolution was anything but a random process.


... the greater the statistical improbability, the less plausible is chance as a solution: that is what improbable means. But the candidate solutions to the riddle of improbability are not, as is falsely implied, design and chance. They are design and natural selection. Chance is not a solution, given the high levels of improbability we see in living organisms, and no sane biologist ever suggested that it was.” [Emphasis added]

Dawkins Belief there is “A generalized process for optimizing”

He goes on his apparently subconscious defense of pantheism [pg 139]:

It is clear that here on Earth we are dealing with a generalized process for optimizing biological species, a process that works all over the planet, on all continents and islands, and at all times. … if we wait another ten million years, a whole new set of species will be as well adapted to their ways of life as today’s species are to theirs. This is a recurrent, predictable, multiple phenomenon, not a piece of statistical luck recognized with hindsight. [Emphasis added
Dawkin’s “generalized process for optimizing” is Omnipresent (“all continents and islands … all times”), Omnipotent (“whole new set of species”) and Omniscient (“as well adapted to their ways of life as today’s species”). Change it to “Generalized Optimizing Device” and we have our familiar Pantheistic “GOD”. QED :^)

Opposition to Homosexuality by the “American Taliban”

In another passage worthy of Ann Coulter, Dawkins [pg 289] notes the Afghan Taliban punishment for homosexuality was execution by being buried alive and compares that to a statement by what he calls the “American Taliban” Rev. Jerry Falwell who said “AIDS is not just God’s punishment for homosexuals; it is God’s punishment for the society that tolerates homosexuals.” One does not have to agree with Falwell to recognize Dawkins’s analogy as an awful exaggeration.
