The Power of Alief

My colleague, the philosopher Tamar Gendler, describes the Grand Canyon Skywalk, a glass walkway that extends 70 feet from the canyon’s rim. It is supposedly a thrilling experience. So thrilling
that some people drive several miles over a dirt road to get there and then discover that they are too afraid to step onto the walkway. In all of these cases, people know they are perfectly safe, but they are nonetheless frightened.
In an important pair of papers, Gend-ler introduces a novel term to describe the mental state that underlies these reactions: She calls it “alief.” Beliefs are attitudes that we hold in response to how things are. Aliefs are more primitive. They are responses to how things seem. In the above example, people have beliefs that tell them they are safe, but they have aliefs that tell them they are in danger. Or consider the findings of Paul Rozin, a professor of psychology at the University of Pennsylvania, that people often refuse to drink soup from a brand-new bedpan, eat fudge shaped like feces, or put an empty gun to their head and pull the trigger. Gendler notes that the belief here is: The bedpan is clean, the fudge is fudge, the gun is empty. But the alief is stupid, screaming, “Filthy object! Dangerous object! Stay away!”
The point of alief is to capture the fact that our minds are partially indifferent to the contrast between events that we believe to be real versus those that seem to be real, or that are imagined to be real. This extends naturally to the pleasures of the imagination. Those who get pleasure voyeuristically watching real people have sex will enjoy watching actors having sex in a movie. Those who like observing clever people interact in the real world will get the same pleasure observing actors pretend to be such people on television. Imagination is Reality Lite—a useful substitute when the real pleasure is inaccessible, too risky, or too much work.
