# 2.05 explained — Tractatus Logico-Philosophicus

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

## What happens

The totality of existent atomic facts determines not only what is the case but also what is not the case, establishing a complete logical space of possibilities.

## Themes in this chapter

### Logical Atomism

The notion that atomic facts, both existent and non-existent, form the foundation of reality.

## Key lines

> The totality of existent atomic facts also determines which atomic facts do not exist.

All the atomic facts that actually exist define, by their absence, which atomic facts are false or not real.

_This establishes a binary logical space where every atomic fact is either true or false._
