This collection of seven essays draws on work done in 2010. The author takes up several topics in the systemic analysis of Judaisms and deals with comparisons of Judaisms. The papers include two commentaries on the current state of the academic study of Judaism. The reason for periodically collecting and publishing essays and reviews is to give them a second life, after they have served as lectures or as summaries of monographs or as free-standing articles or as expositions of Judaism in collections of comparative religions. This re-presentation serves a readership to whom the initial presentation in lectures or specialized journals or short-run monographs is inaccessible. Some of the essays furthermore provide a precis, for colleagues in kindred fields, of fully worked out monographs.
