This paper aims to challenge epistemological and political implications for concepts of equality/inequality and diversity. For this it focuses on implications of both indisputam umas com as outras para ver qual estabelecerá uma nova "certeza" baseada em um novo discurso do senso comum em progresso.(CARLSON; APPLE, 2000, p. 11) P ERHAPS ONE OF THE FEW CERTAINTIES we can tell today is that we are living in… uncertain times. We live in a time of often systematic questions about certainties, truths, interpretation -metanarratives -about the past and future of the universe, the earth, human societies and beings, and those concerning linear prediction of the future.Some say we are living in a new era -postmodernity (LYOTARD, 1993); for others modernity is not over yet and its progress does not imply rupture (HABERMAS, 1990); or that postmodernity is only 'a state of spirit, rather than a crystallized reality ' (ROUANET, 1987); and others emphasized that we live in a time of transition (GATTI, 2005, p. 3).On the plan of knowledge production, meta-theoretical approaches and theories are reviewed: Portuguese prefixes neo and pós designate contemporary strands of thought clashing to provide the dominant interpretation in our time (poststructuralism, post-feminism, postcolonialism, Neo-Marxism, NeoGramscianism, among many others). Sometimes, the rupture is indicated by the adjective critical: Critical pedagogy and critical multiculturalism are some of the various ways of distinguishing the traditional from the contemporary, the past from the future in this labyrinth of theoretical productions and current political proposals. The previous knowledge is kept as traditional, and we propose the rupture of disciplinary barriers and the organization, to start using the chaos theory.This theoretical production, which tries to catch and reflect about the complexity of our times, seems to me and others (CARLSON; APPLE, 2000),
