September 2021 marks the centenary of the birth of one of the most influential figures in the history and philosophy of education, Paulo Freire . This special issue of LAIC offers a critical analysis of the continuing international impact of his ideas. The editors solicited scholars and educators from around the world to give testimony to the extent to which Freire's work on critical pedagogy has been influential in their contexts and how a Freirean perspective can contribute to the achievement of 'Quality Education,' the United Nations Educational, Scientific and Cultural Organization's Sustainable Development Goal #4 (UNESCO SDG-4). Specifically, contributors were invited to discuss the continuing relevance of Freire's vision to the provision of 'Quality Education' in the field of language and intercultural communication.The celebration of a centenary leads us to honour the past while it recognises the importance of a figure, or an event, in the present and, therefore, its influence in the future. In the present case, we review and appraise the legacy of Paulo Freire. The creative interlinking between past, present and future, that is, between reflection and action, critique and possibility, between conscientização 1 and prática cidadã, 'the practice of citizenship,' represents Freire's beacon for the present and future. Ultimately, Freire's goal is to promote change, defined as a deep social transformation, not by imposing a linear model of progress, say 'quality' in the UNESCO terms, but by offering each community, indeed each individual, the opportunity to discover the distinctive contribution they can make to the overall improvement of the quality of life, be it within, for example, the ethos of buen vivir ('living well') or that of a 'good' society. To this end, Freire focused his attention on the political and dialogical character of education, on the validation of students' heritage and local knowledge, and on the creative and critical role of the teacher. Gadotti (2007), in his preface to the Portuguese version of Freire's Education and Change, considered that among Freire's overall 'generating topics' (temas geradores), that is, concepts that can prompt action and inspire change, the most inspirational and urgent, were precisely conscientização and mudança, in the sense of 'active awareness' and 'social transformation.' Paulo Freire's work has been studied around the world, with different interpretations, and put into practice through multiple adaptations to local cultural circumstances. His intention was precisely to offer an educational vision and examples of practice which could trigger profound change both in educational and in social contexts, anywhere discrimination and oppression were taking place. Though broadly applicable, the social and political environment of his praxis and the historical and cultural inspiration of his theory were profoundly rooted in Brazil and both actively converse with the ideas of the main Brazilian and Latin American educational scholars of his time.Although he often...
