David Chalmers in Edge:
We’ve got these bodies and these brains, which work okay, but we also have minds. We see, we hear, we think, we feel, we plan, we act, we do; we’re conscious. Viewed from the outside, you see a reasonably finely tuned mechanism. From the inside, we all experience ourselves as having a mind, as feeling, thinking, experiencing, being, which is pretty central to our conception of ourselves. It also raises any number of philosophical and scientific problems. When it comes to explaining the objective stuff from the outside—the behavior and so on—you put together some neural and computational mechanisms, and we have a paradigm for explaining those.
When it comes to explaining the mind, particularly the conscious aspects of the mind, it looks like the standard paradigm of putting together mechanisms and explaining things like the objective processes of behavior leaves an explanatory gap. How does all that processing give you a subjective experience, and why does it feel like something from the inside doesn’t look like it’s directly addressed by these methods? That’s what people call the hard problem of consciousness, as opposed to, say, the easy problems of explaining behavior.
Discussion can then spin off in a thousand directions. Could you explain conscious experience in terms of the brain? Does it require something fundamentally new? Does it exist at all? Lately, I’ve been interested in coming at this from a slightly different direction. We’ve got the first-order problem of consciousness, and then it’s often hard for people from AI research, or neuroscience, or psychology to say, “There’s a problem here, but I’m not quite sure what I can do with it.”

“I claim the right to the United States, for myself and my children and my uncles and cousins, by manifest destiny.” The claimant is Suketu Mehta, in This Land Is Our Land: An Immigrant’s Manifesto. The reference to manifest destiny isn’t merely trolling. Mehta’s thesis is that extensive migration from poor parts of the globe to the US is as inevitable and justified as the westward migration that built this country. He goes on:
When we design a skyscraper we expect it will perform to specification: that the tower will support so much weight and be able to withstand an earthquake of a certain strength.
The cheerleaders for Prime Minister Narendra Modi of India are cheering for Partition redux, a world-class massacre, ethnic cleansing. The brute power of Hindu supremacy has its own logic, and it requires not only that Kashmiris be denied a future but also that they be humiliated and punished for their past sin of not being grateful Indians. While individual Indian Muslims across the country are being lynched for trading beef or
The authors find little proof of increasing busyness among the population. Yes, as expected, people were spending far more time on digital devices in 2015 than they were in 2000. But the data provides little evidence that people now spend more time multitasking or that they’re switching more often from one activity to another, which might make our time seem fragmented and frantic.
In novels spanning several hundred years of history, Toni Morrison used her historical imagination and her remarkable gifts of language to chronicle the horrors of slavery and Jim Crow, and their continuing fallout on the everyday lives of black Americans. Violent, heart-wrenching events occur in her fiction: a runaway slave named Sethe cuts the throat of her baby daughter with a handsaw to spare her the fate she suffered herself as a slave (
Drugs work stunningly well to control HIV—but not in everyone, and not without side effects. That’s why a small cadre of patients known as elite controllers has long fascinated researchers: Their immune system alone naturally suppresses HIV for decades without drugs. Now one team, inspired by success in mice, hopes to endow HIV-infected people with tailormade immune cells that target HIV, in effect creating elite controllers in the clinic. The immune strategy has risks, but it builds on increasingly popular cancer treatments with T cells engineered to have surface proteins, called chimeric antigen receptors (CARs), that can recognize markers on the surfaces of tumor cells and destroy the cancer. Such CAR T cells can also be tailored to identify and eliminate HIV-infected cells. This approach was tested in HIV-infected humans long before CAR T cells proved their worth against cancer, but it roundly failed. The field wants “to move what’s been learned from cancer back to HIV, completing the circle,” says Steven Deeks, an HIV/AIDS clinician at the University of California, San Francisco, who first tested a CAR T cell against the virus in the late 1990s.
I think it’s very difficult to make the case for an objective morality if you’re using the word ‘objective’ in a strong sense, either to mean a universal morality or a foundational morality that all people everywhere understand and accept in a globalising world.
Fiction shines a light on the human condition by putting people into imaginary situations and envisioning what might happen. Science fiction expands this technique by considering situations in the future, with advanced technology, or with utterly different social contexts. Seth MacFarlane’s show The Orville is good old-fashioned space opera, but it’s also a laboratory for exploring the intricacies of human behavior. There are interpersonal conflicts, sexual politics, alien perspectives, and grappling with the implications of technology. I talk with Seth about all these issues, and maybe a little bit about whether it’s a good idea to block people on Twitter.
The mass shootings over the weekend in El Paso, Texas, and Dayton, Ohio, killed at least 31 people and wounded scores more. Those incidents were just the latest such deadly attacks in the United States, which has tallied more than 250 since Jan. 1, according to a new report by

During the three years that Billy Budd took shape, Britten and Forster occasionally disagreed about just how brazen the piece should be. In one instance, Forster complained that one of Claggart’s arias was just not hot-blooded enough. “I want passion—love constricted, perverted, poisoned, but nevertheless flowing down its agonising channel; a sexual discharge gone evil,” Forster wrote. “Not soggy depression or growling remorse.” Britten—who had largely been circumspect about his own homosexuality, publicly avoiding the subject of his long relationship with the tenor Peter Pears—strongly disagreed, and as a consequence, a rift opened up between librettist and composer, the one a daring idealist, the other a more cautious realist.
