What has happened to the American male?For a long time,he seemed utterly confident in his manhood,sure of his masculine (男性的) role in society,easy and definite in his sense of sexual identity.The frontiersmen(边远地区居民) of James Fenimore Cooper,for example,never had any concern about masculinity; they were men,and it did not occur to them to think twice about it.Even well into the twentieth century,the heroes of Dreiser,of Fitzgerald,of Hemingway remain men.But one begins to detect a new theme emerging in some of these authors,especially in Hemingway:the theme of the male hero increasingly preoccupied with proving his virility(男子气概)to himself.And by mid-century,the male role had plainly lost its rugged clarity of outline.Today men are more and more conscious of maleness not as a fact but as a problem.The ways by which American men affirm their masculinity are uncertain and obscure.There are multiplying signs,indeed,that something has gone badly wrong with the American male’s conception of himself.
