# 3.263 explained — Tractatus Logico-Philosophicus

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

## What happens

Wittgenstein explains that the meanings of primitive signs can be conveyed through elucidations, which are propositions containing those signs, but such elucidations presuppose prior understanding of the signs' meanings.

## Themes in this chapter

### Limits of Language and Thought

Elucidations highlight the boundary where language can only explain signs if their meanings are already known, pointing to limits of explicit definition.

### Logical Atomism

Primitive signs are the basic elements of logical atomism, whose meanings are given through elucidations rather than further analysis.

## Character check-ins

### Mr. Wittgenstein

Author of the Tractatus, presenting the nature of primitive signs and elucidations.

## Key lines

> The meanings of primitive signs can be explained by elucidations. Elucidations are propositions which contain the primitive signs. They can, therefore, only be understood when the meanings of these signs are already known.

Primitive signs are defined by propositions that include them, but these definitions only work if you already know what the signs mean.

_Clarifies the circularity inherent in explaining basic terms._
