How consciousness works – Michael Graziano

Scientific talks can get a little dry, so I try to mix it up. I take out my giant hairy orangutan puppet, do some ventriloquism and quickly become entangled in an argument. I’ll be explaining my theory about how the brain — a biological machine — generates consciousness. Kevin, the orangutan, starts heckling me. ‘Yeah, well, I don’t have a brain. But I’m still conscious. Kevin is the perfect introduction. Many thinkers have approached consciousness from a first-person vantage point, the kind of philosophical perspective according to which other people’s minds seem essentially unknowable. Lately, the problem of consciousness has begun to catch on in neuroscience. I believe that the easy and the hard problems have gotten switched around. In a period of rapid evolutionary expansion called the Cambrian Explosion, animal nervous systems acquired the ability to boost the most urgent incoming signals. Attention requires control. I call this the ‘attention schema theory’. And then what?

Evangelists of Democracy LIKE THE human-rights movement, democracy promotion is a radical project of social and political transformation whose adherents will not or cannot acknowledge either the ideological or the revolutionary character of their enterprise. In this, democracy promotion should be understood as a subset of contemporary liberalism—the only major modern ideology that denies it is an ideology at all. More precisely, it is the end state of human political organization after all the other ideologies have withered away, the future’s moral default position. There is irony in this proud assertion of openness to new ideas and dismissal of “closed,” undemocratic societies on the grounds that they, as Soros once complained, “claim to be in possession of the ultimate truth.” What is it about democracy promotion that drives otherwise hardheaded people to such extremes?

More Than 1 Billion People Are Hungry in the World For many in the West, poverty is almost synonymous with hunger. Indeed, the announcement by the United Nations Food and Agriculture Organization in 2009 that more than 1 billion people are suffering from hunger grabbed headlines in a way that any number of World Bank estimates of how many poor people live on less than a dollar a day never did. But is it really true? Are there really more than a billion people going to bed hungry each night? Our research on this question has taken us to rural villages and teeming urban slums around the world, collecting data and speaking with poor people about what they eat and what else they buy, from Morocco to Kenya, Indonesia to India. But unfortunately, this is not always the world as the experts view it. Jeffrey Sachs, an advisor to the United Nations and director of Columbia University's Earth Institute, is one such expert. But then there are others, equally vocal, who believe that all of Sachs's answers are wrong. What is going on? Why?

The Science of Why We Don't Believe Science Illustration: Jonathon Rosen "A MAN WITH A CONVICTION is a hard man to change. Tell him you disagree and he turns away. Festinger and several of his colleagues had infiltrated the Seekers, a small Chicago-area cult whose members thought they were communicating with aliens—including one, "Sananda," who they believed was the astral incarnation of Jesus Christ. Through her, the aliens had given the precise date of an Earth-rending cataclysm: December 21, 1954. Festinger and his team were with the cult when the prophecy failed. Read also: the truth about Climategate.At first, the group struggled for an explanation. From that day forward, the Seekers, previously shy of the press and indifferent toward evangelizing, began to proselytize. In the annals of denial, it doesn't get much more extreme than the Seekers. The theory of motivated reasoning builds on a key insight of modern neuroscience (PDF): Reasoning is actually suffused with emotion (or what researchers often call "affect").

The Brain on Trial - David Eagleman Advances in brain science are calling into question the volition behind many criminal acts. A leading neuroscientist describes how the foundations of our criminal-justice system are beginning to crumble, and proposes a new way forward for law and order. On the steamy first day of August 1966, Charles Whitman took an elevator to the top floor of the University of Texas Tower in Austin. The evening before, Whitman had sat at his typewriter and composed a suicide note: I don’t really understand myself these days. By the time the police shot him dead, Whitman had killed 13 people and wounded 32 more. It was after much thought that I decided to kill my wife, Kathy, tonight … I love her dearly, and she has been as fine a wife to me as any man could ever hope to have. Along with the shock of the murders lay another, more hidden, surprise: the juxtaposition of his aberrant actions with his unremarkable personal life. For that matter, so did Whitman.

Down the rabbit hole Do academic discussions belong to the world of make-believe? Writing in 1942, the Oxford Professor of Metaphysics, RG Collingwood, said that dismissing academic discussion for insignificant speech is like “scolding little girls for giving dolls’ tea-parties with empty cups and little boys for playing with wooden swords.” Academic discussions, he added, “belong to the world of make-believe.” Collingwood was specifically talking about my field, political philosophy, as it is done in universities. Reflecting on his words over the last year, I’ve begun to realise how right he was. Political theory seminars and conferences have been getting “curiouser and curiouser.” What I’ve been wondering is, do political philosophers know that their world is mostly make-believe? It is not political philosophy as a whole that is “academic”, or “make-believe”. One of the central questions of academic political philosophy, the supposedly universal question “What is justice?” More philosophy in Prospect:

The Social Psychological Narrative—or—What Is Social Psychology, Anyway? There has been a question lurking in the back of my mind for all those years, which is how can we take this basic knowledge and use it to solve problems of today? I grew up in the turbulent 1960s, in an era where it seemed like the whole world was changing, and that we could have a hand in changing it. Part of my reason for studying psychology in the first place was because I felt that this was something that could help solve social problems. In graduate school and beyond I fell in love with basic research, which is still my first love. It is thrilling to investigate basic questions of self-knowledge and consciousness and unconsciousness. But those other, more applied questions have continued to rattle around and recently come to the fore, the more I realized how much social psychology has to offer. One of the basic assumptions of the field is that it's not the objective environment that influences people, but their constructs of the world. There are lots of other examples.

A History of Violence Edge Master Class 2011 Click on slides to enlarge The other method of measuring violence in pre-state societies is ethnographic vital statistics. What is the rate of death by violence in people who have recently lived outside of state control, namely hunter-gatherers, hunter-horticulturalists, and other tribal groups? There are 27 samples that I know of, where ethnographic demographers that have done the calculation. Now, here is the world as a whole in the 20th century. So: not to put too fine a point on it, but when it comes to life in a state of nature, Hobbs was right, Rousseau was wrong. What was the immediate cause? It's not that these early states had any benevolent interest in the welfare of their subjects, but rather, that tribal raiding and feuding is a nuisance to imperial overlords. The second major historical decline of violence can be captured in this woodcut of a typical day in the life in the Middle Ages. This is a phenomenon that is not restricted to England. Why should literacy matter?

What the science of human nature can teach us After the boom and bust, the mania and the meltdown, the Composure Class rose once again. Its members didn’t make their money through hedge-fund wizardry or by some big financial score. Theirs was a statelier ascent. They got good grades in school, established solid social connections, joined fine companies, medical practices, and law firms. Wealth settled down upon them gradually, like a gentle snow. You can see a paragon of the Composure Class having an al-fresco lunch at some bistro in Aspen or Jackson Hole. A few times a year, members of this class head to a mountain resort, carrying only a Council on Foreign Relations tote bag (when you have your own plane, you don’t need luggage that actually closes). Occasionally, you meet a young, rising member of this class at the gelato store, as he hovers indecisively over the cloudberry and ginger-pomegranate selections, and you notice that his superhuman equilibrium is marred by an anxiety. Help comes from the strangest places. Ms.
