How Frege Changed Philosophy: Analytic vs. Continental Philosophy

How did philosophy become logical? And why did one quiet mathematician reshape the entire future of analytic philosophy? In this episode, we turn to Gottlob Frege, one of the most influential yet historically underappreciated figures in modern philosophy. While thinkers like Moore and Russell rejected British Idealism and called for clarity, it was Frege who created the logical tools that made their new vision possible. Frege’s Begriffsschrift introduced a revolutionary formal language that surpassed traditional Aristotelian logic, allowing philosophers to analyze structure, meaning, and inference with unprecedented precision. His work on arithmetic sought to ground mathematics in pure logic, and his distinction between sense and reference fundamentally transformed philosophy of language. But this revolution carried tension within it. Frege believed logic could secure certainty itself — until a letter from Bertrand Russell revealed a devastating paradox at the heart of his system. That moment would reshape the trajectory of analytic philosophy and set the stage for the emergence of Ludwig Wittgenstein. This episode explores: • Why Aristotelian logic was no longer enough for modern philosophy • Frege’s invention of modern logical notation (Begriffsschrift) • Logicism and the attempt to derive arithmetic from logic • Why Frege rejected psychological accounts of meaning and truth • The distinction between sense and reference • The Morning Star / Evening Star puzzle • The birth of philosophy of language • Russell’s paradox and the first crisis of analytic philosophy • How Frege’s work prepares the ground for Wittgenstein This episode is part of an ongoing series tracing the formation of analytic and continental philosophy and how the split between these traditions emerged.
