What happens

Wittgenstein discusses the number of possible groups of truth-conditions for n elementary propositions, noting that these groups can be ordered in a series.

Themes in this chapter

  • Logical Atomism

    The discussion of elementary propositions and their truth-conditions is central to logical atomism.

  • Logic and Tautology

    The ordering of truth-conditions relates to the logical structure of propositions.

Characters to notice

Key passages

  • For n elementary propositions there are L n possible groups of truth-conditions.

    Given n elementary propositions, the number of distinct sets of truth-conditions is L n.

    Clarifies the combinatorial nature of truth-conditions.

  • The groups of truth-conditions which belong to the truth-possibilities of a number of elementary propositions can be ordered in a series.

    The sets of truth-conditions corresponding to the truth-possibilities of several elementary propositions can be arranged sequentially.

    Highlights the possibility of ordering truth-condition groups.
