Comparative and International Education is a seemingly infinite field, and it has always tested new frontiers since it was launched as a field of scholarly enquiry 200 years ago by the vision of Marc-Antoine Jullien. The philanthropic mission which Jullien spelled out for the field remains its most noble. The contributions to this book look afresh at this mission, within the context of twenty-first century globalised society, while also highlighting and re-assessing other sources in the field. This book was originally published as a special issue of Compare: A Journal of Comparative and International Education.
