Gladwell's newest

• Malcolm Gladwell details the development of a system to predict box-office hits in The New Yorker.

As is typical with Gladwell, the above summary doesn't do justice to the range of subject areas he can cover in a page without appearing to strain himself. Good stuff, as always.

The most famous dictum about Hollywood belongs to the screenwriter William Goldman. “Nobody knows anything,” Goldman wrote in “Adventures in the Screen Trade” a couple of decades ago. “Not one person in the entire motion picture field knows for a certainty what’s going to work. Every time out it’s a guess.” One of the highest-grossing movies in history, “Raiders of the Lost Ark,” was offered to every studio in Hollywood, Goldman writes, and every one of them turned it down except Paramount: “Why did Paramount say yes? Because nobody knows anything. And why did all the other studios say no? Because nobody knows anything. And why did Universal, the mightiest studio of all, pass on Star Wars? . . . Because nobody, nobody—not now, not ever—knows the least goddamn thing about what is or isn’t going to work at the box office.”

What Goldman was saying was a version of something that has long been argued about art: that there is no way of getting beyond one’s own impressions to arrive at some larger, objective truth. There are no rules to art, only the infinite variety of subjective experience. “Beauty is no quality in things themselves,” the eighteenth-century Scottish philosopher David Hume wrote. “It exists merely in the mind which contemplates them; and each mind perceives a different beauty.” Hume might as well have said that nobody knows anything.

But Hume had a Scottish counterpart, Lord Kames, and Lord Kames was equally convinced that traits like beauty, sublimity, and grandeur were indeed reducible to a rational system of rules and precepts. He devised principles of congruity, propriety, and perspicuity: an elevated subject, for instance, must be expressed in elevated language; sound and signification should be in concordance; a woman was most attractive when in distress; depicted misfortunes must never occur by chance. He genuinely thought that the superiority of Virgil’s hexameters to Horace’s could be demonstrated with Euclidean precision, and for every Hume, it seems, there has always been a Kames—someone arguing that if nobody knows anything it is only because nobody’s looking hard enough.
