The creative writing of the intellectual artists Roberto Corrêa dos Santos and Teixeira Coelho, unclassifiable according to the usual parameters of academic writing in literature, points to other spaces within current practices in literary criticism. Such writing motivates a study in which redescriptions of the discourse produced by literary criticism in the past two decades are compared with redescriptions of critical positioning produced in the field of visual art. The literary productions of Roberto Corrêa dos Santos and Teixeira Coelho, seen as the creation of new instruments, are found to echo the experiences of visuality in contemporary art, in which essentialism, representationalism and foundationism are questioned both by critics and artists. The critical philosophical radicalism of neopragmatism, which addresses such issues and is scarcely represented in Brazilian academic culture, is included in the comprehensive dialogue offered in this dissertation, with a view to a sharp widening of perspectives.
