The elevation of the wild, uncivilized boy into a hero of the age remained a constant even as American society itself evolved, convulsed and transformed. While Fiedler was sitting at his desk in Missoula, Mont., writing his monomaniacal tome, a youthful rebellion was asserting itself in every corner of the culture. The bad boys of rock ‘n’ roll and the pouting screen rebels played by James Dean and Marlon Brando proved Fiedler’s point even as he was making it. So did Holden Caulfield, Dean Moriarty, Augie March and Rabbit Angstrom — a new crop of semi-antiheroes in flight from convention, propriety, authority and what Huck would call the whole “sivilized” world.

From there it is but a quick ride on the Pineapple Express to Apatow. The Updikean and Rothian heroes of the 1960s and 1970s chafed against the demands of marriage, career and bureaucratic conformity and played the games of seduction and abandonment, of adultery and divorce, for high existential stakes, only to return a generation later as the protagonists of bro comedies. We devolve from Lenny Bruce to Adam Sandler, from “Catch-22” to “The Hangover,” from “Goodbye, Columbus” to “The Forty-Year-Old Virgin.”

But the antics of the comic man-boys were not merely repetitive; in their couch-bound humor we can detect the glimmers of something new, something that helped speed adulthood to its terminal crisis. Unlike the antiheroes of eras past, whose rebellion still accepted the fact of adulthood as its premise, the man-boys simply refused to grow up, and did so proudly. Their importation of adolescent and preadolescent attitudes into the fields of adult endeavor (see “Billy Madison,” “Knocked Up,” “Step Brothers,” “Dodgeball”) delivered a bracing jolt of subversion, at least on first viewing. Why should they listen to uptight bosses, stuck-up rich guys and other readily available symbols of settled male authority?

That was only half the story, though. As before, the rebellious animus of the disaffected man-child was directed not just against male authority but also against women.
