This book focuses at the margins of adult education, work and civil society. Rather than focusing on active participants and active participation, the objective is to scrutinize the whole adult population in terms of participation, and to pay special attention to those who are so easily left out of studies concerning adult education, learning at work or active participation in civil society. The aim of the book is to bring into the discussion the views of those who do not find attending adult education possible and who thus form a challenge for the promotion of active citizenship. In the collection of articles researchers from various disciplines and with cross-disciplinary interests in adult education and marginalisation meet and discuss with each other within and beyond their own disciplines.
