Our Knowledge of the External World as a Field for Scientific Method in Philosophy

In these lectures the author explores how the tools of modern logic can turn philosophy into a genuine science. Using the work of Frege as a starting point, he shows how careful analysis of language and concepts can clarify the bridge between raw sensory impressions and the abstract structures of space, time and matter found in physics. Along the way, he acknowledges the valuable role of older philosophical systems while arguing that only a method independent of personal bias can yield reliable knowledge.

The central example focuses on the relationship between sense data and the mathematical world, drawing on insights from collaborators such as Whitehead and the recent breakthroughs of Cantor and Wittgenstein. Readers are invited to follow a tentative, step‑by‑step reconstruction of these ideas, seeing how logical techniques expose both the possibilities and limits of our understanding. The result is a thoughtful guide to applying scientific rigor to some of philosophy’s most enduring questions.
