What happens

This aphorism questions the applicability of logic to the world, suggesting that logic's existence is contingent upon the world's existence; without a world, logic would have no application.

Themes in this chapter

  • Logic and Tautology

    Explores the necessary connection between logic and the existence of the world, questioning whether logic would be possible without a world.

Characters to notice

  • Mr. Wittgenstein

    Author of the aphorism, posing a rhetorical question about the relationship between logic and the world.

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.
