This volume reconstructs how Neo-Thomism sought to resolve disparities, annul contradictions and reconcile incongruent, new developments. It asks the question why Neo-Thomist ideas and arguments were put into play and how they were transferred across various scientific disciplines and artistic media, growing into one of the most influential master-narratives of the twentieth century. Edward Baring, Dries Bosschaert, James Chappel, Adi Efal-Lautenschläger, Rajesh Heynickx, Sigrid Leyssen, Christopher Morrissey, Annette Mülberger, Jaume Navarro, Herman Paul, Karim Schelkens, Wim Weymans and John Carter Wood reconstruct a bewildering, yet decipherable thought-structure that has left a deep mark on twentieth century politics, philosophy, science and religion.
