The beat generation mainly referred to the youth who were born and brought up around the Second World War. They showed their ignorance of almost everything traditional, such as government authority ,respect for parents, one’s duty, moral standards, and traditional customs. They developed a kind of absolute individualism and liberty. They preferred long hair, mini dresses or close fitting clothes to show off the figure. They advocated （倡导）freedom of sex and cohabitation (同居).Their influence could be seen from the fact that about one third of the American couples living together were not married by law. And the divorce rate was very high. The endless U.S wars abroad and sharp class struggle at home caused many American youths to develop a kind of cynicism. They doubted the existing social system, possibility of harmonious human relations, and the long honored standard for correct behavior. They felt society overlooked their needs. Therefore, they refused to do any duty that was required of them by society. They declared “Don’t believe anyone over thirty.” All this came from the sick society. It’s wrong to imagine they all fought against capitalism in support of revolutionary things. Some of their ideas were even more decadent (颓废的)and impractical.
