The pulp hero, though he may be a renegade, is a guy who doesn’t feel. Anything. Ever. And for the adolescent male — pummeled by emotions left and right, whether arising from sexuality or resulting from his necessary encounters with authority — this hero is a blessing, a relief and a release. The world he lives in, where feelings are totally under control, looks to the adolescent boy like heaven! This hero’s lack of feeling — like Star Trek’s Spock — is what allows him to be a genius, or allows him to shoot the bad guys and/or aliens, without a quiver to his lip.
