# Essential and Accidental Features of Propositions explained — Tractatus Logico-Philosophicus

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

## What happens

Wittgenstein distinguishes between essential and accidental features of propositions, where accidental features arise from the specific method of producing the propositional sign, while essential features are those that allow the proposition to express its sense.

## Themes in this chapter

### Picture Theory of Language

The distinction between essential and accidental features relates to how propositions picture reality, with essential features being those that enable the picture to convey its sense.

### Nonsense and Meaning

The essential features of a proposition are what allow it to express a sense, distinguishing meaningful propositions from nonsense.

## Character check-ins

### Mr. Wittgenstein

Author of the distinction between essential and accidental features of propositions.

## Key lines

> A proposition possesses essential and accidental features. Accidental are the features which are due to a particular way of producing the propositional sign. Essential are those which alone enable the proposition to express its sense.

A proposition has both essential and accidental characteristics. Accidental features come from the specific method used to create the propositional sign, while essential features are those that allow the proposition to convey its meaning.

_Clarifies the distinction between what is necessary for a proposition to have meaning and what is contingent on its expression._
