The complex societies we now inhabit oblige us to question, reformulate or even rupture the traditional socio-political frameworks in which social pedagogy and the social professions have been developed and in which the theories that explain and justify them have been constructed. These frameworks have institutionalised concepts, practices and methodologies that often no longer fit within the complexity of today’s constantly changing realities. The aim of this article is to propose and analyse some key foundations for understanding the social professions and the actions they carry out. It concerns itself with generating questions that link social pedagogy and the social professions with the complexity of today’s social life. The questions address the current content of what we refer to as ‘the social’ and its relationship with other dimensions such as politics, culture and the environment. Among other issues, the article addresses how the social professions have developed within the political framework of the welfare state. Based on the answers to these questions, we argue in favour of updating the term ‘social’ with renewed connotations, and of defining the ‘good life’ as the reference point that must give it meaning.
