Wittgenstein argues that the essence of a proposition is what is common to all propositions expressing the same sense, and similarly, the essence of a symbol is what all symbols serving the same purpose share.
What happens
Wittgenstein argues that the essence of a proposition is what is common to all propositions expressing the same sense, and similarly, the essence of a symbol is what all symbols serving the same purpose share.
Themes in this chapter
Picture Theory of Language
The notion of a common essence across propositions aligns with the picture theory, where propositions share a logical form with the facts they depict.
Logical Atomism
The search for what is essential in propositions reflects the atomist project of analyzing language into fundamental, shared logical elements.
Characters to notice
- Mr. Wittgenstein
Author of the proposition, presenting the core idea of essential features in propositions and symbols.
Key passages
“The essential in a proposition is therefore that which is common to all propositions which can express the same sense.”
What is crucial to a proposition is the feature shared by every proposition that conveys the same meaning.
Wittgenstein identifies the invariant core of propositions with identical sense.
“And in the same way in general the essential in a symbol is that which all symbols which can fulfill the same purpose have in common.”
Similarly, the essence of a symbol is the property common to all symbols that serve the same function.
Extends the principle of shared essence from propositions to symbols broadly.
