This two-volume reference investigates the historical and philosophical evolution of the foundations of mathematics from the late eighteenth century through the early twentieth century. William Bragg Ewald, a scholar of law and philosophy, compiles and translates a vast array of primary source documents to trace the development of mathematical thought. By providing access to previously untranslated works alongside established classics, the text establishes a rigorous framework for understanding the shift from intuitive geometry to formal axiomatic systems. The collection serves as a comprehensive archive for researchers examining the intellectual lineage of modern logic.

Experts and reviewers identify this collection as a foundational resource that effectively complements existing anthologies in the history of logic. Readers frequently note the academic density of the prose and the high quality of the translations, making it a standard reference for serious students of mathematical philosophy.
