# 3.03 explained — Tractatus Logico-Philosophicus

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

## What happens

Wittgenstein asserts that it is impossible to think anything illogical, because doing so would require thinking illogically, which is a contradiction in terms.

## Themes in this chapter

### Limits of Language and Thought

The proposition directly addresses the boundary of thinkable content, asserting that logic is a precondition for thought.

## Character check-ins

### Mr. Wittgenstein

Author of the proposition; presents a foundational limit on thought.

## Key lines

> We cannot think anything unlogical, for otherwise we should have to think unlogically.

It is impossible to entertain an illogical thought, because that would require thinking in a way that violates logic itself.

_Wittgenstein argues that logical form is inherent to the very act of thinking._
