Huius recensione subiectum liber est, qui ab Ulrico G. Leinsle sub titulo Einführung in die scholastische Theologie Germanice conscriptus, a M. J. Miller magna cum sollertia Anglice redditus est. In hoc libro Leinsle materiae historicae copiam diligentissime collegit ac ordine disposuit, contributionem faciens singularem et novam ad philosophiae historiam cognoscendam. Scholaribus et viris scientificis, qui hisce legatis intellectualiis studeant, liber dictus conspectum offerit latum et valde comprehensivum principaliorum problematum ac methodorum theologiae scholasticae, rebus tamen minutis non neglectis. Leinsle demonstravit, locupletem ac multiformem traditionem scholasticam partem principalem habuisse in civilizatione occidentali constituenda.The subject of this review is the book Introduction to Scholastic Theology by Ulrich G. Leinsle which was originally published in Germany as Einführung in die scholastische Theologie (the English translation of the book was very well rendered by M. J. Miller). Leinsle gathered rich historical material which he organized into an original, impressive contribution to our knowledge of the history of philosophy. It offers students and scholars interested in this intellectual legacy a comprehensive, panoramic overview of the main problems and methods of Scholastic theology and provides a quick glimpse of many sub-topicsas well. Leinsle has shown that the rich and varied Scholastic tradition played a key role in constituting our Western civilization.
