U no és ningú. Anti-authoritarianism, Anti-clericalism, Anti-militarism. Brossa never faltered in his profound republican and Catalanist convictions, and his unquenchable libertarian spirit. Throughout the Franco dictatorship he had no hesitation in supporting the anti-Franco underground. At that time his sympathies lay with the PSUC, the Catalan communist party, which in 1971 brought out a clandestine edition of one of his books, fervently critical of the dictatorial regime: Des d'un got d'aigua fins al petroli (From a Glass of Water to Petrolium), written in 1950. In 1979 he published the bibliophile book U no és ningú (One is Nobody) with Antoni Tàpies, a collection of prose pieces that also date from 1950. Brossa produced countless literary, visual and object works in which his anti-authoritarian, anti-clerical and anti-militarist ideology is clearly apparent.
