NATURAL-BORN DUALISTS

Conversation:
[5.11.04]
Topic:

"In the domain of bodies, most of us accept that common sense is wrong. We concede that apparently solid objects are actually mostly empty space, consisting of tiny particles and fields of energy. Perhaps the same sort of reconciliation will happen in the domain of souls, and it will come to be broadly recognized that our dualist belief system, though intuitively appealing, is factually mistaken. Perhaps we will all come to agree with Richard Dawkins and Daniel Dennett and join the side of the "brights": those who reject the supernatural and endorse the world-view established by science."

 

LEARNING TO EXPECT THE UNEXPECTED

Conversation:
[4.17.04]
Topic:

"A black swan is an outlier, an event that lies beyond the realm of normal expectations. Most people expect all swans to be white because that's what their experience tells them; a black swan is by definition a surprise. Nevertheless, people tend to concoct explanations for them after the fact, which makes them appear more predictable, and less random, than they are. Our minds are designed to retain, for efficient storage, past information that fits into a compressed narrative. This distortion, called the hindsight bias, prevents us from adequately learning from the past."

 

LANGUAGE, BIOLOGY, AND THE MIND

Conversation:
[1.26.04]
Topic:

"For a long time the fields of biology and psychology have been quite separate, and only in the last few years people have started thinking about brain imaging and about how the brain and mind relate. But they haven't really thought that much about another part of biology: developmental biology. Brain imaging tells you something about how the brain works, but that doesn't tell you anything about how the brain gets to be the way that it is. Of course, we also have the human genome sequence and have made enormous advances in genetics and related fields, and what I've been trying to do in the last few years is to relate all of the advances in biology to what people have been finding out in cognitive development and language acquisition."

 

THE LANDSCAPE

Conversation:
[12.2.03]
Topic:

"What we've discovered in the last several years is that string theory has an incredible diversity—a tremendous number of solutions—and allows different kinds of environments. A lot of the practitioners of this kind of mathematical theory have been in a state of denial about it. They didn't want to recognize it. They want to believe the universe is an elegant universe—and it's not so elegant. It's different over here. It's that over here. It's a Rube Goldberg machine over here. And this has created a sort of sense of denial about the facts about the theory. The theory is going to win, and physicists who are trying to deny what's going on are going to lose."

 

NEW PILLS FOR THE MIND

Conversation:
[12.2.03]
Topic:

"Most of the psychiatric drugs we use today are refinements of drugs whose value for mental disorders was discovered by accident decades ago. Now we can look forward to a more rational way to design psychiatric drugs. It will be guided by the identification of the gene variants that predispose certain people to particular mental disorders such as schizophrenia or severe depression."

 

THE ADJACENT POSSIBLE

Conversation:
[11.9.03]
Topic:

"An autonomous agent is something that can both reproduce itself and do at least one thermodynamic work cycle. It turns out that this is true of all free-living cells, excepting weird special cases. They all do work cycles, just like the bacterium spinning its flagellum as it swims up the glucose gradient. The cells in your body are busy doing work cycles all the time."

 

PERSONAL FABRICATION

Conversation:
[7.21.03]
Topic:

"We've already had a digital revolution; we don't need to keep having it. The next big thing in computers will be literally outside the box, as we bring the programmability of the digital world to the rest of the world. With the benefit of hindsight, there's a tremendous historical parallel between the transition from mainframes to PCs and now from machine tools to personal fabrication. By personal fabrication I mean not just making mechanical structures, but fully functioning systems including sensing, logic, actuation, and displays."

 

THE POLITICS OF CHRISTIANITY

Conversation:
[7.15.03]
Topic:

"The kind of Christianity that pervades the religious right in this country divides the world between the saved and the damned, between God's people and Satan's people, between good and evil. We have all seen how this is played out in our politics. I used to think that President Bush was using this language as a political ploy. I still think he is, but I also think—to my disappointment—that he also believes it. His conviction that he is God's chosen one to "rid the world of evildoers" blinds him to the evil that he—and we, as Americans—are capable of doing. The conviction that we are on the side of good—of God—is, however, an ancient one—enormously powerful."

 

THE MAKING OF A PHYSICIST

Topic:

something about his life and his attitude toward the world and toward physics.
