# 3.3441 explained — Tractatus Logico-Philosophicus

> Chapter companion for Tractatus Logico-Philosophicus by Ludwig Wittgenstein.

## What happens

Wittgenstein discusses the commonality among all notations for truth-functions, noting that they can all be replaced by the notations for negation and disjunction, thereby showing how a specific notation can yield general insights.

## Themes in this chapter

### Logic and Tautology

The passage illustrates how truth-functional notations share a common logical form, reducible to negation and disjunction.

## Character check-ins

### Mr. Wittgenstein

Author of the Tractatus, presenting the logical structure of truth-functional notation.

## Key lines

> We can, for example, express what is common to all notations for the truth-functions as follows: It is common to them that they all, for example, can be replaced by the notations of “ ~ p ” (“not p ”) and “ p ∨ q ” (“ p or q ”).

All truth-functional notations share the property that they can be expressed using only negation and disjunction.

_This highlights the underlying unity of logical notation._
