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

## What happens

Tautology and contradiction involve combinations of signs, but these relations are meaningless and unessential to the symbol.

## Themes in this chapter

### Nonsense and Meaning

The relations between signs in tautology and contradiction are described as meaningless, highlighting the boundary between sense and nonsense.

## Key lines

> Of course the signs are also combined with one another in the tautology and contradiction, i.e. they stand in relations to one another, but these relations are meaningless, unessential to the symbol.

In tautology and contradiction, signs are indeed combined, but these combinations have no meaning and are not essential to what the symbol represents.

_Clarifies that the logical relations in tautologies and contradictions do not contribute to meaningful content._
