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.
 …  emergent, but that word means different things to different people  …  an electron is determined by the local values of other quantum fields at the position of the electron — and by nothing else /Sean Carroll/16-09-13


Science Should Stay Clear of Metaphysics  …  “realists” and “anti-realists.”  …  “anti-realists” or “empiricists”  …  van Fraassen  …  He rescued empiricism from the dead end of logical positivism  …  rain gods, musical spheres, phlogiston, ether, multiple universes, big bangs, cosmic inflation, dark matter, dark energy, and singularities. A scientist who believes in the existence of these unobserved entities  …  “empirical adequacy”  …  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.”  …  Can science explain religion and spirituality?  …  category mistake /16-09-13


Noam Chomsky  …  fails to support Chomsky’s assertions  …  learning of a child’s first language does not rely on an innate grammar module  …  ability to classify the world into categories  …  relations among things  …  to grasp what others intend to communicate  …  if you understand what language is, you comprehend a little bit more about human nature  …  2002 .. computational recursion  …  a single genetic mutation that occurred be­tween 100,000 and 50,000 years ago  …  the notion of universal grammar is plain wrong  …  usage-based linguistics  …  The grammar must be something they discern beyond the words themselves, given that the sentences share little in common at the word level. /16-09-09


Art of the lie  …  Politicians have always lied.  …  Trump is the leading exponent of “post-truth” politics  …  “feel true” but have no basis in fact  …  And he is not alone. Members of Poland’s government assert that a previous president, who died in a plane crash, was assassinated by Russia. Turkish politicians claim  …  Britain to leave  …  If, like this newspaper, you believe that politics should be based on evidence, this is worrying.  …  the heart of what is new: that truth is not falsified, or contested, but of secondary importance  …  Feelings, not facts  …  us-versus-them mindset  …  lies, rumour and gossip spread with alarming speed  …  NASA scientist says Mars is probably uninhabited; Professor Snooks says it is teeming with aliens. It’s really a matter of opinion.  …  Pro-truthers stand and be counted  …  The truth has powerful forces on its side.  …  who makes contradictory promises to different audiences will soon be exposed on Facebook or YouTube  …  especially those that draw on science  …  The deeper worry is for countries like Russia and Turkey /16-09-09

Are we really so modern?  …  Enlightenment philosophers  …  Copernicus in 1543  …  philosopher is a professor of philosophy  …  discovery of America destroyed established geography, the Reformation destroyed the established Church, and astronomy destroyed the established cosmos.  …  It’s impossible to imagine what, if anything, could produce a comparable effect on us today.  …  our universe is actually a simulation run on a computer  …  One of the most popular names for the unexplainable is God /16-08-31


What became of the Christian intellectuals?  …  “nativism,” “reactionary,” even “fascism” appear in political conversation  …  religious ressentiment  …  decline of Christian (or “Judeo-Christian”) civilization  …  They should be intellectuals who speak the language of other intellectuals, including the most purely secular, but they should also be fluent in the concepts and practices of faith.  …  serious Christian intellectuals  …  interpreters and watchmen  …  Finkelstein  …  What democracy needed was a metaphysical justification  …  the Christian intellectual was the product of World War II  …  The Christian intellectuals chose to disappear.  …  very different authority: the scientist  …  The term “Judeo-Christian” is almost coterminous with the Cold War  …  anti-intellectualism in American life  …  fear is not a Christian habit of mind  …  a difference, not however between a closed environment and an open one but between environments that are differently closed  …  dilemmas that Christian intellectuals began to face in the Sixties and still face today, and perhaps no solution at all  …  you grow more and more public but less and less intellectual  …  separate-but-equal domains  …  rise of illiberal and confrontational movements that often seem to be rooted in religious identity  …  Richard Rorty comment, “Of course the theists can talk, but we don’t have to listen” /16-08-30


Death and Doctors  …  The mortality rate of human beings is still 100%  …  the least attractive stage of human life, the years beyond ninety  …  thank you, but no.  …  euthanasia  …  still the act remains as fearful as ever  …  absolute irreversibility of the procedure  …  that is what the patient wanted. But did he?  …  if you want to die in an acceptable manner, you have to actually try to escape from the hospital to a hospice /16-08-30


galaxy has been discovered  …  made almost entirely of dark matter  …  Dragonfly 44  …  300 million light years away  …  scientists have no idea what dark matter is /16-08-29


Wastefulness of Modern Dining /16-08-29


A.I.  …  artificial intelligence .. try to imitate or augment human intelligence  …  The first is recognition intelligence .. can recognize patterns  …  The second stage is cognitive intelligence .. making inferences from data.  …  The third stage will be reached only when we can create virtual human beings, who can think, act, and behave as humans do.  …  It’s ironic that we define artificial intelligence with respect to its ability to replicate human intelligence  …  man-machine symbiosis  …  computers do the best they can (that is being consistent, objective, precise), and humans do our best (creative, imprecise but adaptive) /16-08-28

Werner Herzog  …  Lo and Behold: Reveries of the Connected World.  …  Whenever a self-driving car makes a mistake, automatically all the other cars know about it, including future unborn cars.  …  The ability of cars to develop artificial intelligence is so much greater than the ability of people to keep up with them.  …  Could it be that the Internet starts to dream of itself?  …  Elon Musk  …  the perfect vacation: to infinity and beyond. /16-08-23


Werner Herzog said of virtual reality  …  you get tired of it fairly quickly  …  more convincing was animated films. Digitally created landscapes  …  So you have the content first, and then the technology follows suit. In this case, we do have a technology, but we don’t have any clear idea how to fill it with content.  …  I was not caught in a virtual reality is when I travelled on foot.  …  Our understanding of our brain, of our mind, is in its infancy.  …  whether we do live in a virtual reality all the time anyway /16-08-23


Must science be testable?  …  The general theory of relativity is sound science; ‘theories’ of psychoanalysis, as well as Marxist accounts of the unfolding of historical events, are pseudoscience. This was the conclusion reached a number of decades ago by Karl Popper,  …  falsifiability  …  string theory  …  a general framework – the most mathematically sophisticated one available at the moment – to resolve a fundamental problem in modern physics: general relativity and quantum mechanics  …  vibrating superstrings, multiple, folded, dimensions of space-time and other features of the theory are impossible to test experimentally  …  Richard Dawid  …  speculative, if innovative, type of epistemology  …  difficult to separate such ‘science’ from New Age thinking, or science fiction,’ said George Ellis  …  Post-empirical science is an oxymoron  …  Leonard Susskind ..
