Key passages
“Suppose all elementary propositions were given me: then we can simply ask: what propositions I can build out of them. And these are all propositions and so are they limited.”
If we have all the simplest factual statements, the only propositions possible are those we can combine from them, which defines the boundary of what can be said.
This highlights the combinatorial nature of propositions and their inherent limitation.
