# 5.153 explained — Tractatus Logico-Philosophicus

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

## What happens

Wittgenstein asserts that probability is not an intrinsic property of propositions; events are binary—they either occur or they do not.

## Themes in this chapter

### Logic and Tautology

The proposition denies intrinsic probability, aligning with the view that logical propositions are either true or false without degrees.

## Character check-ins

### Mr. Wittgenstein

Author of the proposition

## Key lines

> A proposition is in itself neither probable nor improbable. An event occurs or does not occur, there is no middle course.

A proposition does not carry its own likelihood; an event either happens or it doesn't—there is no in-between.

_Wittgenstein rejects the idea that probability is a property of propositions themselves._
