On the group matrix and the morality of the nuclear deterrent: The worldview of Gregory van der Kleij

Abstract

This article presents the writings of Gregory van der Kleij, group analyst and Catholic priest, whose experiences of the holocaust during the Second World War shaped his thinking, not only as a therapist but also as a campaigner against the nuclear arms race. The author re-visits two significant articles on the group matrix published in this journal in the 1980s and introduces the reader to a little-known monograph addressed to the Catholic community which examines the moral dilemma faced by Christians during the Cold War. The monograph contains an exhortation to rise up in protest against what Gregory considers to be ‘the madness’ of high-level thinking on the morality of the nuclear deterrent.
