# 5.5423 explained — Tractatus Logico-Philosophicus

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

## What happens

Wittgenstein discusses the perception of complexes, explaining that perceiving a complex involves recognizing how its constituents are combined. He uses the example of a cube figure that can be seen in two ways, illustrating that we perceive two different facts depending on our focus.

## Themes in this chapter

### Logical Atomism

The analysis of complexes into constituents and their combination reflects logical atomist ideas.

### Picture Theory of Language

Perceiving a complex as a combination of constituents parallels the idea of propositions as pictures of facts.

## Character check-ins

### Mr. Wittgenstein

Author of the proposition, exploring the nature of perception and complexes.

## Key lines

> To perceive a complex means to perceive that its constituents are combined in such and such a way.

Perceiving a complex is recognizing how its parts are arranged together.

_Clarifies the relationship between perception and the structure of complexes._

> This perhaps explains that the figure can be seen in two ways as a cube; and all similar phenomena.

This might account for ambiguous figures like the Necker cube and similar perceptual illusions.

_Connects the philosophical point to a concrete perceptual example._
