Concerning that which cannot be talked about, we should not say anything.
If a lion could talk, we could not understand him.
You can't think decently if you're not willing to hurt yourself
The sense of the world must lie outside the world... What we cannot speak about we must remain silent about... What can be described can happen too, and what is excluded by the laws of causality cannot be described.
