His writing influenced generations of intellectuals ; he coined the phrase " the sexual revolution " and according to one historian acted as its midwife . During the 1968 student uprisings in Paris and Berlin , students scrawled his name on walls and threw copies of The Mass Psychology of Fascism at police .
