"Principia Mathematica" (by Russell and Whitehead)

"Principia Mathematica," by Bertrand Russell and Alfred North Whitehead, is a foundational work in mathematical logic that aims to show how all mathematical truths can be derived from basic logical principles. The authors develop a rigorous system of symbols and rules to formalize mathematics, attempting to prove that mathematics is an extension of logic. This work addresses issues of consistency and completeness, shaping modern logic and the philosophy of mathematics by illustrating how complex ideas can be built systematically from fundamental logical concepts.
