Tractatus vs. Investigations
| Tractatus | Philosophical Investigations |
| Set the limitation of what can be thought that sets precise limits to what can be said | How language functions in various everyday situations |
| Try to resolve the confusion about the logic of our language, which is the root of philosophical problems. |
Tractatus
Vienna Circle
- The interaction with the Vienna circle (Rudolf Carnap, Moritz Schlick, Herbert Feigl) was not fruitful.
- There were some positive discussions about logic and the foundation of mathematics, but Wittgenstein did not agree on the circle’s view on metaphysics. The Vienna circle members misread/misunderstood Tractatus and misused Wittgenstein’s idea to support their positivistic philosophy.
