Wittgenstein argues that the world must have substance (simple objects), otherwise the sense of a proposition would be contingent on the truth of another proposition, leading to an infinite regress.

What happens

Wittgenstein argues that the world must have substance (simple objects), otherwise the sense of a proposition would be contingent on the truth of another proposition, leading to an infinite regress.

Themes in this chapter

  • Logical Atomism

    The argument for substance (simple objects) as necessary for determinate sense of propositions.

  • Limits of Language and Thought

    Highlights the condition that sense must be independent of other propositions' truth, pointing to limits of what can be said.

Characters to notice

  • Mr. Wittgenstein

    Author of the proposition, presenting a logical argument for the necessity of substance in the world.

Key passages

  • If the world had no substance, then whether a proposition had sense would depend on whether another proposition was true.

    Without simple objects, the meaningfulness of a statement would rely on the truth of another statement, creating an endless chain.

    Illustrates the necessity of atomic facts for grounding sense.
