Benjamin Brown (scholar)
Benjamin Brown is an Israeli professor and researcher of Judaism and Jewish thought. He is a lecturer at the Department of Jewish Thought at the Hebrew University of Jerusalem and a senior research fellow at the Van Leer Jerusalem Institute. Brown is known for his studies on Orthodox Judaism, especially the ultra-Orthodox community, from theological, Jewish-legal and historical perspectives. He was the first scholar to trace the development of the concept Daas Torah and its various usages in the Haredi world. In addition, he has published extensively on Halakhah, the Musar Movement and Hasidism.
Philosophical Work
Although Brown was involved in philosophy from his youth and taught it in various settings, he refrained from publishing in the field until the age of fifty. Since then, he has authored two systematic philosophical monographs with European academic publishers.''Thoughts and Ways of Thinking'' (2017)
Thoughts and Ways of Thinking: Source Theory and Its Applications introduces a novel epistemic logic called the Source Calculus, which serves as the foundation for an epistemological system termed Source Theory. The central concept of this theory is the source, the entity that provides data. A subject adopts particular sources as truth-sources, thereby determining which data will be accepted as true. When more than one source exists, a "source model" is required to regulate their relationship — through hierarchy, compartmentalization, or other principles. Consistent application of Source Theory leads to a relativistic position that entails three paradoxes, resolved by pragmatic rules that impose limits on source adoption.The book applies this framework to three areas of philosophy: religion, law, and language. Brown raises questions such as: why religious believers persist in their faith even when it seems to conflict with reason ; why different judges weigh moral values differently in legal interpretation; and why individuals ascribe different meanings to the same words. These inquiries are all framed by the overarching question: why do human beings think in different ways from one another? In some cases the book also proposes possible methods for adjudicating between such differences.
''The Foundations of Rational Metaphysics'' (2025)
The Foundations of Rational Metaphysics is a systematic treatise presenting a two-layered metaphysical theory, called "the first metaphysic" and "the second metaphysc". The first metaphysic addresses the general principles of any world whatsoever, analyzing fundamental categories that allow the differentiation of objects. Closely related to formal logic, but sharply deiverging from the existing Predicate Calculus, it develops new approaches to predication, negation, and quantification, and introduces a unifying "theory of manifolds" for mereology, set theory, and collection theory. From this framework Brown constructs a new Concept Calculus, capable of formulating eight basic concepts of any world whasoever and identifying its "first partitioner."The second metaphysic explores the principles of our world as mediated by our basic faculties of cognition. Brown proposes that our world consists of four ontological spaces: thought, language, reality, and noumena. By analyzing their relations and central concepts in epistemology and ontology, he identifies twenty-four fundamental concepts unique to our world. Together, the two metaphysical layers provide a comprehensive, large-scale system that employs innovative logical and analytical tools, a type of enterprise often absent from contemporary metaphysics.
