The Internet has become not only a tool for disseminating knowledge through scientific publications, but it also has the potential to shape scientific research through expanding the field of metaknowledge - the study of knowledge itself, according to an article published by University of Chicago researchers in the journal Science.

WHAT is the difference between a sceptic and a denier? When I call myself a sceptic, I mean that I take a scientific approach to the evaluation of claims. A climate sceptic, for example, examines specific claims one by one, carefully considers the evidence for each, and is willing to follow the facts wherever they lead. A climate denier has a position staked out in advance, and sorts through the data employing "confirmation bias" - the tendency to look for and find confirmatory evidence for pre-existing beliefs and ignore or dismiss the rest. Scepticism is integral to the scientific process, because most claims turn out to be false. Weeding out the few kernels of wheat from the large pile of chaff requires extensive observation, careful experimentation and cautious inference. Science is scepticism and good scientists are sceptical. Denial is different. It is the automatic gainsaying of a claim regardless of the evidence for it - sometimes even in the teeth of evidence. Denialism is typically driven by ideology or religious belief, where the commitment to the belief takes precedence over the evidence. Belief comes first, reasons for belief follow, and those reasons are winnowed to ensure that the belief survives intact.

Brain, bodily awareness, and the emergence of a conscious self: these entities and their relations are explored by Germanphilosopher and cognitive scientist Metzinger. Extensively working with neuroscientists he has come to the conclusion that, in fact, there is no such thing as a "self" -- that a "self" is simply the content of a model created by our brain - part of a virtual reality we create for ourselves. But if the self is not "real," he asks, why and how did it evolve? How does the brain construct the self? In a series of fascinating virtual reality experiments, Metzinger and his colleagues have attempted to create so-called "out-of-body experiences" in the lab, in order to explore these questions. As a philosopher, he offers a discussion of many of the latest results in robotics, neuroscience, dream and meditation research, and argues that the brain is much more powerful than we have ever imagined. He shows us, for example, that we now have the first machines that have developed an inner image of their own body -- and actually use this model to create intelligent behavior. In addition, studies exploring the connections between phantom limbs and the brain have shown us that even people born without arms or legs sometimes experience a sensation that they do in fact have limbs that are not there. Experiments like the "rubber-hand illusion" demonstrate how we can experience a fake hand as part of our self and even feel a sensation of touch on the phantom hand form the basis and testing ground for the idea that what we have called the "self" in the past is just the content of a transparent self-model in our brains. Now, as new ways of manipulating the conscious mind-brain appear on the scene, it will soon become possible to alter our subjective reality in an unprecedented manner. The cultural consequences of this, Metzinger claims, may be immense: we will need a new approach to ethics, and we will be forced to think about ourselves in a fundamentally new way. At

What had been lacking until relatively recently was an overarching framework or theory through which to grasp the nature of consciousness. The lack of a general theory of consciousness, of how it comes to be that there is something that it is like to be, was really the last rational bastion of opposition to the scientific assertion that consciousness emerges from the brain.

German philosopher of mind Thomas Metzinger is one of the world's top researchers on consciousness, instrumental in its renaissance as a respectable problem for scientific enquiry. From out-of-body experiences to lucid dreaming, anarchic hand syndrome to phantom limbs, his investigations have taken him to places few dare to go. Be spooked, bewildered and amazed.

There is a strange and mysterious world that surrounds us, a world largely hidden from our senses.The quest to explain the true nature of reality is one of the great scientific detective stories.Clues have been pieced together from deep within the atom, from the event horizon of black holes, and from the far reaches of the cosmos.It may be that that we are part of a cosmic hologram, projected from the edge of the universe. Or that we exist in an infinity of parallel worlds. Your reality may never look quite the same again.

 the tools of philosophy can be important to everyone because it potentially helps one think better, more clearly, and with greater perspective about almost everything.  There are numerous specific topic areas in academic philosophy, many of interest only to a few, even among philosophers, but there are features and techniques common to all of them, and it is those features and techniques which also can apply to almost anything in life.  These features have to do with reasoning and with understanding concepts, and, to some small extent, with creativity.  Normally, all other things being equal, the better one understands anything and can think clearly and logically about it, the better off one will be, and the better one will be able to act on that understanding and reasoning. (It is my view, for example, that better conceptual understanding by NCAA and NFL administrators would lead to a far more workable and acceptable "instant replay review" policy.) Furthermore, philosophy in many cases is about deciding which goals and values are worthy to pursue -- what ends are important.  One can be scientific or pragmatic about pursuing one's goals in the most efficient manner, but it is important to have the right or most reasonable goals in the first place.  Philosophy is a way of scrutinizing ideas about which goals are the most worthy one.  A healthy philosophical debate about what is ideal or which ideals ought to be sought and pursued, is important.  Efficiency in the pursuit of the wrong values or ends is not a virtue. President John F. Kennedy, in speaking at Amherst College on a day honoring poet Robert Frost, said: "The men who create power make an indispensable contribution to the nation's greatness, but the men who question power make a contribution just as indispensable, especially when that questioning is disinterested, for they determine whether we use power or power uses us."  And "When power leads man towards arrogance, poetry reminds him of his limi

The Great Debate On November 6th, 2010 a panel of renowned scientists, philosophers, and public intellectuals gathered to discuss what impact evolutionary theory and advances in neuroscience might have on traditional concepts of morality. If human morality is an evolutionary adaptation and if neuroscientists can identify specific brain circuitry governing moral judgment, can scientists determine what is, in fact, right and wrong? The panelists were psychologist Steven Pinker, author Sam Harris, philosopher Patricia Churchland, physicist Lawrence Krauss, philosopher Simon Blackburn, bioethicist Peter Singer and The Science Network's Roger Bingham.  Recorded live at the Arizona State University Gammage auditorium.  "The Great Debate" was sponsored by the ASU Origins Project in collaboration with the ASU Sandra Day O'Connor College of Law Center for Law, Science and Innovation; the Faculty of Philosophy at the University of Cambridge; and The Science Network. ------ Sam Harris is the author of the New York Times bestsellers "The Moral Landscape: How Science Can Determine Human Values," "The End of Faith" and "Letter to a Christian Nation." "The End of Faith" won the 2005 PEN Award for Nonfiction. Harris has a doctorate in neuroscience from UCLA and a degree in philosophy from Stanford University. He is a co-founder and CEO of Project Reason, a nonprofit foundation devoted to spreading scientific knowledge and secular values in society.

Whenever we talk about the beginning of modern science, we remember the scientific revolution that began with the work of Copernicus and the emblematic "Galileo case". Galileo was summoned twice to the court of the Inquisition and in the final judgement; he was forced to recant his belief in the movement of the earth around the sun.
