Quick Summary

The "calculus of reason" refers to the philosophical endeavor to apply the rigorous methods and formal structures of mathematics to the study of philosophy. This approach, known as mathematicism, seeks to establish consistency and completeness in philosophical analysis.1

Key aspects include:
* Using general mathematical methods for philosophical investigation, pioneered by René Descartes.1
* Applying axiomatization to metaphysical systems, deducing tenets from basic axioms, as exemplified by Benedict de Spinoza.1
* Developing formal systems, or calculi, modeled on mathematical logic to represent and clarify philosophical concepts, as seen in the work of Bertrand Russell and Ludwig Wittgenstein.123

This approach aims to ensure logical rigor and systematic understanding in philosophical reasoning.14
