Dolphins have been declared the world's second most intelligent creatures after humans, with scientists suggesting they are so bright that they should be treated as "non-human persons".

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.

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.

It looks like physics works differently in different places. If so, everything we think we know about the cosmos may be wrong

From The Philosophical Review LXXXIII, 4 (October 1974): 435-50

The failure of social scientists to seriously question their own ideological and methodological assumptions contributes to the complex interrelationship between global ecological and individual psychological problems. Much of the literature on the tragedy of the commons focuses on saving the global commons through increased centralization and regulation, at the expense of the individual's autonomy and psychological sense of community. "Utopian" speculation in general and anarchist political analysis in particular are necessary correctives to misplaced attempts to merely rearrange the elements of the status quo rather than to radically alter it in a direction more in keeping with both survival and human dignity.

Physicist Brian Greene was propelled into the spotlight thanks to The Elegant Universe, his bestseller on string theory. Now he's turned his attention to parallel worlds. He tells Amanda Gefter about his favourite multiverse, why we might be living in a computer simulation and the questions that keep him awake at night

He predicts that quantum computers will be produced within 20 years. ----- The two towering achievements of modern physics are quantum theory and Einsteins general theory of relativity. Together, they explain virtually everything about the world in which we live. But almost a century after their advent, most people havent the slightest clue what either is about. Radio astronomer, award-winning writer and broadcaster Marcus Chown talks to fellow stargazer Fred Watson about his book Quantum Theory Cannot Hurt You. - Australian Broadcasting Corporation Marcus Chown is an award-winning writer and broadcaster. Formerly a radio astronomer at the California Institute of Technology, he is now cosmology consultant of the weekly science magazine New Scientist. The Magic Furnace, Marcus' second book, was chosen in Japan as one of the Books of the Year by Asahi Shimbun. In the UK, the Daily Mail called it "a dizzy page-turner with all the narrative devices you'd expect to find in Harry Potter". His latest book is called Quantum Theory Cannot Hurt You.

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
