Kurt Lewin, the founder of field theory, can be regarded as a congenial precursor to contemporary systemic thinking and action. This anthology addresses the question of what added value a field-theoretical perspective can provide when applied to current issues in leadership, consulting, and therapy. Furthermore, the book explores the intriguing phenomenon of why Lewin, despite being highly praised as one of the most significant pioneers of 20th-century psychology, has only been superficially received both scientifically and practically. This anthology is published in conjunction with the 16th Public Professional Conference of the DGGO "Field Forces - What Moves People, Groups, and Organizations? Lewin's Lens More Relevant Than Ever" (June 18-20, 2015). Contributions from: Klaus Antons, Hella Gephart, Hans Jellouschek, Jürgen Kriz, Helmut Lück, Erika Spiess, Maria.
