Do parents really matter?
… Thomas Bouchard
… separating identical twins at birth
… Their characters were often remarkably in step, as were their intellects, their behaviours, even their hobbies and eccentricities.
… parenting influences — are all secondary when it comes to personality, behaviour or intelligence
… Steven Pinker .. ‘A cosmic ray mutates a stretch of DNA, a neurotransmitter zigs instead of zags, the growth cone of an axon goes left instead of right, and one identical twin’s brain might gel into a slightly different configuration from the other’s.’ In other words, we should not presume that random chance plays a vanishingly small role in making us the people that we are today.
… We may not hold their tomorrows in our hands but we surely hold their todays
… Pinker, meanwhile, makes the point that it should be enough for us to remember that our children are human beings, worthy of the same ethical treatment we give to our friends, other relatives, and even to strangers. So protect your children, provide for them, be good to them, and make memories with them. Apart from that, don’t expect to have very much say in how they turn out. /17-06-18
Computers are starting to reason like humans
… A new type of neural network can reason about complex relationships
… Google’s DeepMind
… it has already beaten humans at a complex image comprehension test
… Statistical AI, or machine learning, is great at pattern recognition, but not at using logic.
… symbolic AI can reason about relationships using predetermined rules, but it’s not great at learning on the fly
… to bridge the gap
… forcing the network to discover the relationships that exist between the objects
… “There is an object in front of the blue thing; does it have the same shape as the tiny cyan thing that is to the right of the gray metal ball?”
… other machine-learning algorithms were right 42% to 77% of the time. Humans scored a respectable 92%. The new relation network combo was correct 96%
… “Sandra picked up the football” and “Sandra went to the office.” These were followed by questions like: “Where is the football?” (the office)
… “Lily is a Swan. Lily is white. Greg is a swan. What color is Greg?” (white)

… The Invention of Sex
… He rescued Adam and Eve from obscurity, devised the doctrine of original sin—and the rest is sexual history
… something fundamentally damaged about the entire human species
… In the “Confessions,” written around 397, Augustine described what happened in the bathhouse many years earlier.
… intense and equally cryptic phrases evoke a succession of unhappy affairs with women
… his restless sexual energies
… Monica engineered another change in her son’s life
… Of his mistress’s feelings, he gives us no glimpse, noting simply, “She went back to Africa
… no bodily pleasure, no matter how great, could ever match the happiness of the saints
… Augustine and Monica experienced something remarkable: they felt themselves climbing higher and higher, through all the degrees of matter and through the heavenly spheres and, higher
… the thirty-two-year-old son and the fifty-five-year-old mother to reach this climax together
… Adam and Eve .. originale peccatum
… Holy virginity became pregnant, not by conjugal intercourse, but by faith—lust being utterly absent
… Some people can even move their ears, either one at a time or both together.
… Along with these doctrinal purposes, Augustine’s obsessive engagement with the story of Adam and Eve spoke to something in his life.

the Heart of AI
… No one really knows how the most advanced algorithms do what they do. That could be a problem.
… it was unlike anything demonstrated by Google, Tesla, or General Motors, and it showed the rising power of artificial intelligence. The car didn’t follow a single instruction provided by an engineer or programmer. Instead, it relied entirely on an algorithm that had taught itself to drive by watching a human do it.
… The system is so complicated that even the engineers who designed it may struggle to isolate the reason for any single action.
… deep learning
… to diagnose deadly diseases, make million-dollar trading decisions, and do countless other things to transform whole industries.
… Starting in the summer of 2018, the European Union may require that companies be able to give users an explanation for decisions that automated systems reach.
… to serve ads or recommend songs. The computers that run those services have programmed themselves, and they have done it in ways we cannot understand.
… we humans can’t always truly explain our thought processes either
… Deep Patient, was trained using data from about 700,000 individuals, and when tested on new records, it proved incredibly good at predicting disease.
… the machine essentially programs itself.
… deep learning is a particularly dark black box.
… It might be part of the nature of intelligence that only part of it is exposed to rational explanation.
… certain images could fool such a network into perceiving things that aren’t there
… Even if somebody can give you a reasonable-sounding explanation [for his or her actions], it probably is incomplete, and the same could very well be true for AI
… a natural part of the evolution of intelligence itself is the creation of systems capable of performing tasks their creators do not know how to do. /17-06-05

… Sensations are the building blocks of consciousness.
… neural systems evolved to enable animals to move in their environments
… stimuli exist in analog form and are converted into digital form by the receptor cells and the neural circuits
… a small portion of an undifferentiated stream of stimuli is selected by the organism and given a specific identity.
… There is nothing “mental” or “physical” in this account of sensations. That distinction makes sense only much further down the line in the evolution of neural systems and requires the development of memory and neural plasticity /17-04-28
… does the quantum state ultimately represent some objective aspect of reality, or is it a way of characterizing something about us, namely, something about what some person knows about reality?
… do these results rule out the idea that the quantum state is a feature of our mind? Well, yes and no.
… fundamental assumptions. One is that the world is always in some ontic state, a determinate physical state independent of what we happen to know

Daniel Dennett’s naturalistic account of consciousness
Four billion years ago, Earth was a lifeless place. Nothing struggled, thought, or wanted. Slowly, that changed. Seawater leached chemicals from rocks; near thermal vents, those chemicals jostled and combined. Some hit upon the trick of making copies of themselves that, in turn, made more copies. The replicating chains were caught in oily bubbles, which protected them and made replication easier; eventually, they began to venture out into the open sea. A new level of order had been achieved on Earth. Life had begun.
The tree of life grew, its branches stretching toward complexity. Organisms developed systems, subsystems, and sub-subsystems, layered in ever-deepening regression. They used these systems to anticipate their future and to change it. When they looked within, some found that they had selves—constellations of memories, ideas, and purposes that emerged from the systems inside. They experienced being alive and had thoughts about that experience. They developed language and used it to know themselves; they began to ask how they had been made.
… His newest book, “From Bacteria to Bach and Back,” tells us, “There is a winding path leading through a jungle of science and philosophy, from the initial bland assumption that we people are physical objects, obeying the laws of physics, to an understanding of our conscious minds.”

Sean Carroll, The Big Picture: On the Origins of Life, Meaning, and the Universe Itself
Our goal is to offer plausibility sketch that the world can ultimately be understood on the basis of naturalism. We don't know how life began, or how consciousness works, but we can argue that there's little or no reason to look beyond the natural world for the right explanations. We can always be wrong in that belief; but then again, we can always be wrong about any belief.
… science is precluded from making statements about supernatural forces because these are outside its provenance. Not really. Science should be interested in determining the truth, whatever that truth may be- natural, supernatural or otherwise.
Is it possible that God exists, and communicates with human beings in ways that circumvent our ordinary senses? Absolutely. As Plantinga correctly points out, if theism is true,
… two competing propositions: one is that God Exists,
… the other is naturalism, which would explain such experiences the same way it would explain dreams or hallucinations or other impressions
… To decide between them, we need to see which one coheres better with other things we believe about the world.
Given the profound and deeply personal nature of prayer, meditation, and contemplation, it can seem frivolous or diminishing to relate them to psychedelics or the activity of neurons, or even to dispassionate scientific investigation of any sort. But if we wont to undertake our journey to the best possible understanding of the world with the intellectual honesty it deserves, we always have to question our beliefs, consider alternatives, and compare them with the best evidence we can gather. It may be the case that transcendent experiences arise from a direct connection with a higher level of reality, but the only way to know is to weight that idea against what we learn from the world by looking at it.

It looks like scientists and philosophers might have made consciousness far more mysterious than it needs to be

… But during conscious states, a typical echo ranges widely over the cortical surface, disappearing and reappearing in complex patterns. Excitingly, we can now quantify the complexity of these echoes by working out how compressible they are
… Complexity measures of consciousness

… what brains do, not just where they do it

… selfhood is also best understood as a complex construction generated by the brain
… introspection can be a poor guide
… Instead of ‘I think therefore I am’ we can say: ‘I predict (myself) therefore I am.’ The specific experience of being you (or me) is nothing more than the brain’s best guess of the causes of self-related sensory signals.

The dark universe
… Scientists have theories about dark matter and dark energy — and some observations — but both are poorly understood
1. Is there a dark-matter particle?
… Subatomic dark-matter particles, analogous to the particles that make up the visible Universe, would fit nicely into current physics models
… Weakly interacting massive particles (WIMPs) are the leading candidates
2. Does dark matter interact with anything?
… the only known effect is gravitational pull
… dark matter seems to interact with other dark matter
… for signs of dark matter interacting with ordinary matter
3. Does the cosmological constant explain dark energy?
… The simplest explanation for dark energy is that there is a small force that acts in opposition to gravity
… theory says that it is 10120 greater than that, a Universe-sized discrepancy
4. What will eventually happen to the Universe?
… big rip /16-10-04

… material from the surface of an asteroid called Bennu.
… Slowly, nothing became everything.
… For a cell to survive, it requires three ingredients: nucleic acids, like DNA and RNA, to guide its development; amino acids to build proteins; and a lipid envelope to protect it from the elements.
… spacecraft to an asteroid, dig up a pristine sample, and bring it back home
… official approach to Bennu won’t begin until August of 2018 /16-10-03
… surprisingly simple relationship between the way galaxies move, and the distribution of ordinary matter within them

Consciousness and Downward Causation
… qualia, the irreducibly subjective components of our experience of the world.
… zombies are harder to conceive of than you might originally have guessed
… respect for the laws of physics, but an insistence that consciousness can’t reduce to the physical
1. Consciousness cannot be accounted for by physical particles obeying mindless equations.
2. Human beings seem to be made up — even if not exclusively — of physical particles.
3. To the best of our knowledge, those particles obey mindless equations, without exception.
4. Therefore, consciousness does not exist.

… By way of example, there is evidence for what goes on inside a proton, but that does not allow us to assume the existence of quarks.
… It is a matter of fact whether or not electrons are real.
… The physical world is certainly real
… The role of science is to create theories that are useful in making predictions about the observable world.
… The sole criterion of scientific success is empirical success.
… The realist disagrees, “No! Empirical adequacy does not go far enough. The criterion of scientific success is that a theory has to be entirely true.”

how mind arises from matter or how, in turn, mind acts on the brain
… there is no nonphysical soul or ego, or at least no evidence for that
… consciousness is a kind of con game the brain plays with itself
… The brain is a computer that evolved to simulate the outside world. Among its internal models is a simulation of itself — a crude approximation of its own neurological processes. The result is an illusion. Instead of neurons and synapses, we sense a ghostly presence — a self — inside the head. But it’s all just data processing. “The machine mistakenly thinks it has magic inside it,” Dr. Graziano said. And it calls the magic consciousness.
… There is a gap in the explanation where suddenly a miracle seems to occur.
… For lack of a precise mechanism describing how minds are generated by brains, some philosophers and scientists have been driven back to the centuries-old doctrine of panpsychism — the idea that consciousness is universal, existing as some kind of mind stuff inside molecules and atoms.
… Consciousness doesn’t have to emerge. It’s built into matter, perhaps as some kind of quantum mechanical effect.
… perceptronium: atoms arranged so they can process information and give rise to subjectivity

our thinking about evolution
… evolutionary function
… different forms of purpose
… human behaviour is not a ragbag of disconnected behaviour patterns with separate evolutionary histories. What evolves is an emotional constitution which shapes our lives as a whole. We have to explain particular actions by finding their place in it.
… they still believe that, behind this screen, there lie hidden the real causes, elements of evolutionary advantage
… deriving all our motivation from the single stem of “selfishness” – enlightened self-interest – is, says Darwin, radically mistaken.
… The resulting mythology of selfishness suited the Thatcherite age
… genes themselves were not actually solitary but highly co-operative
… simple atomistic pattern was neither workable nor necessary
… natural selection can perfectly well take place at a number of different levels
… The past half-century was the age of reductionism
… Now we are entering the age of holism
… group-selection is particularly plausible in the case of humans because of the invention of speech
… subjective phenomenon as a serious influence in the world
… the constant flow of inner activity by which we respond to the life around us – also affect the world
… Life for us is not just the absence of death.
… a grave objection to the sociobiological insistence that everything has an evolutionary function
… an evolutionary advantage behind every human taste – including, say, the taste for doing mathematics
… are done for their own sake because they fulfil our nature

Wszystko, co istnieje w poznanym dotychczas świecie,zbudowane jest z tych samych elementów fizycznych – atomów – wspólnych dla organizmów żywych i materii nieożywionej. Teza o powstaniu zjawiska życia poprzez jednorazowy akt twórczy nie jest akceptowana przez fizykę. Sądzimy, że życie od około 4 miliardów lat rozwijało się z atomów poprzez formowanie, a następnie przez interakcje prostych cząsteczek chemicznych i makrocząsteczek. W procesie ewolucji powstawało coraz więcej „części”, a relacje między nimi stawały się coraz bardziej złożone. W wyniku tych procesów powstały złożone systemy biologiczne.

Kotarbiński był wprawdzie powszechnie szanowany w czasie swego długiego życia, ale bywało i odwrotnie. W 1943 roku został umieszczony na liście osób przeznaczonych do likwidacji, sporządzonej przez radykalną prawicę. Powodem był jego (umiarkowany) liberalizm lewicowy i filosemityzm. Był też ceniony w PRL, o czym świadczą stanowiska, jakie piastował, i odznaczenia, jakie mu przyznano. Kotarbiński bywał (i nadal tak jest) krytykowany za zbytnią uległość wobec władz PRL. Zupełnie niesłusznie, gdyż jego postawa współpracy wypływała z realizmu praktycznego, a nie sympatii do komunizmu. Jego ateizm i antyklerykalizm sprawiły, że kilka szkół przestało go uważać za patrona po roku 1989, ale niektóre (m.in. w Andrychowie, Dzierżoniowie, Olsztynie) oparły się tej tendencji. Biblioteka Uniwersytetu Warszawskiego ma w swym hallu cztery posągi filozofów (Twardowskiego, Tarskiego, Leśniewskiego, Łukasiewicza), ale zabrakło miejsca dla Kotarbińskiego – jak wieść niesie właśnie z powodów światopoglądowych. Kotarbiński umarł w Laskach pod Warszawą. Tuż przed jego śmiercią przystanął ksiądz przy łóżku i wyciągnął rękę do chorego. Kotarbiński ją uściskał, a duchowny ogłosił potem publicznie, że filozof w ten sposób wyspowiadał się i przyjął ostatnie sakramenty. Przytaczam te fakty nie dla sensacji, ale ku przestrodze. Oto biografia i ocena jednego z wielkich współczesnych Polaków bywają ma- nipulowane gwoli doraźnych potrzeb politycznych.

Richard Dawkins: Brief Candle in the Dark
… The Selfish Gene .. genes, not organisms, were the targets of natural selection.
… for evolution, against design in nature,
… the 'new atheism', a fundamentalist sect that has mounted a scientistic crusade against all religion.
… Dawkins has a quantitative turn of mind, but is better at algorithms than theorems. So indeed is life itself, which is why biology has so few laws.
… Today's genome is much more than a script .. Many researchers continue to find selfish DNA a productive idea, but taking the longer view, the selfish gene per se is looking increasingly like a twentieth-century construct.
… For a time, Dawkins was a rebellious scientific rock star. Now, his critique of religion seems cranky, and his immovably genocentric universe is parochial. /15-09-18

Biologically speaking, we’re not a special act of creation. We’re a twig on the tree of evolution. Third, what is the relationship between our minds and the physical world? Here, we don’t have a settled answer. ... We have an awareness of information we process. What is this mysterious aspect of ourselves? ... a shift from a credulous and egocentric viewpoint to a skeptical and slightly disconcerting one: namely, that we don’t actually have inner feelings in the way most of us think we do. ... Patricia S. Churchland and Daniel C. Dennett. .. How does the brain go beyond processing information to become subjectively aware of information? The answer is: It doesn’t. ... And there is no way for the brain to determine through introspection that the story is wrong, because introspection always accesses the same incorrect information. ... Attention: a real, mechanistic phenomenon that can be programmed into a computer chip. Awareness: a cartoonish reconstruction of attention .. awareness is not an illusion.

But language has always been a grassroots, bottom-up phenomenon. ...
it's hard to imagine what it's like not to know something that you do know.
... biological phenomena were explained in part at the level of molecules, which were explained by chemistry, which was explained by physics. There's no reason that that this process of explanation can't continue. Biology gives us a grasp of the brain, and human nature is a product of the organization of the brain, and societies unfold as they do because they consist of brains interacting with other brains and negotiating arrangements to coordinate their behavior, and so on. Now I know that there is tremendous resistance to this idea, because it's confused with a boogeyman called reductionism ...
A program of unifying the arts and humanities with the psychological sciences and ultimately the biological sciences promises tremendous increases of depth of understanding for all the fields.
It's becoming increasingly clear over the decades and centuries that an understanding of science is central to our understanding of the deepest questions of who we are, where we came from, what matters. /14-06-11
