"in his hippy-anarchist days"

The hippy or hippie subculture originally began in the United States in the 1960s. The group had counterculture beliefs stemming from the tensions in American society that flowed from the Vietnam War, race relations, sexual freedom, women's rights, arguments against authority, and experimentation with drugs, as well as interpretations of consumerism. The drugs enabled the followers of the movement to explore alternate states of consciousness and new ways of thinking. Their beliefs against authority saw the laws and government as something harmful to humanity, and they favoured anarchy, a situation where there is no government, order or control.
