The paper presents the author's reflection on research and teaching over a period of 45 years in a social pedagogy program in the Leuven University (Belgium). While the case is interesting in its own right, it holds broader significance for its contribution to understanding developments in education, adult and community education and social work both in disciplinary terms and regarding practice. It presents the theoretical sources of inspiration from diverse linguistic, cultural, policy and academic contexts. The chronology is organized in four periods marked by turning points that were influenced by internal and external events. The first phase is the pioneering phase. The second is the crisis and recovery phase. The third is the multiplicity phase, and the last phase is that of reinvention. The paper also reflects on some of the major themes and issues that have directed developments in social and cultural pedagogy (both old and recent) such as issues of language, the emergence of a lifelong learning discourse, and the notions of community, solidarity and criticality.
