The Nietzsche Podcast 139: Ludwig Wittgenstein - Philosophical Investigations, pt 2
Apr 28, 2026
They tackle Wittgenstein's private language puzzle and whether sensations can be named privately. Pain, toothaches, and how we teach and show sensations get close scrutiny. The beetle-in-the-box thought experiment and color qualia probe the limits of inner reference. Language games, meaning-as-use, and how words function as tools in social life are central themes.

Episode notes
Privacy Of Sensations Is Grammar Not Empirics
- Wittgenstein treats privacy of sensations as a grammatical necessity, not an empirical claim.
- We can't verify others' sensations by nature of how the words function in our grammar and forms of life.
Philosophy Should Analyze Word Application Not Inner Phenomena
- Wittgenstein shifts focus from analyzing phenomena to analyzing concepts and word application.
- Philosophy should study how words are used in language games rather than seek metaphysical inner entities.
Names Need Shared Practices To Make Sense
- Learning names requires social practices; a child can't learn 'toothache' if no one manifests pain.
- Language needs prepared stations (uses) for names to make sense, so solitary invention lacks purpose.
