Book excerpt: "The controversial works of Brazilian authors Silviano Santiago(1936-) and Caio Fernando Abreu (1948-96) offer distinctive but complementary explorations of male homosexual subjectivities formulated through displacement, exile and the abject. Posso examines the innovative ways in which these writers stage-manage Western poststructuralist thought to critique heterosexist exclusion in Brazil and in globalized popular and folk culture, and he explains how they draw on diverse cultural productions and art works to extend a general undermining of oppositional logic and psychoanalytic theory."
