Key passages
“And if this were not the case, how could we apply logic? We could say: if there were a logic, even if there were no world, how then could there be a logic, since there is a world?”
If logic were not inherently tied to the world, it would be impossible to apply it. One might argue that logic could exist without a world, but then how could it exist given that the world does exist?
Highlights the paradox of logic's dependence on the world for its applicability.
