Superman's costume always bugged me when I was a kid... So you need a secret identity -- cool. But what's the deal with all the rainbow-hued Spandex masks and costumes?... I found the answer to this great metaphysical dilemma in the book Superheroes and Philosophy, edited by Tom Morris and Matt Morris. In various essays, college philosophy professors and others ruminate on profound issues raised by the superhero lifestyle, such as how Batgirl reflects Nietzsche's moral perfectionism. -- Rick de Yampert, Daytona Beach News-Journal, December 15, 2006
