Tractatus Logico-Philosophicus · Chapter
5.46 explained
Wittgenstein argues that once logical signs are correctly introduced, the sense of all their possible combinations is already given.
What happens
Wittgenstein argues that once logical signs are correctly introduced, the sense of all their possible combinations is already given. This implies that the proper primitive signs are not specific logical operators like disjunction or existential quantification, but rather the most general form of their combinations.

- Logic and Tautology
The passage discusses how logical signs, once introduced, determine the sense of all combinations, pointing to the tautological nature of logical truths.
- General Form of Proposition
Wittgenstein introduces the idea that the general form of proposition, rather than specific logical constants, is the fundamental primitive sign.
Characters to notice
- Mr. Wittgenstein
Author of the Tractatus, presenting the argument about logical signs and the general form of propositions.
Key passages
“When we have rightly introduced the logical signs, the sense of all their combinations has been already introduced with them”
If we correctly define the logical symbols, we have already defined the meaning of every possible combination of them.
Wittgenstein emphasizes that logical constants are not independent but derive their meaning from the system of signs.
“the proper general primitive signs are not “ p ∨ q ”, “ ( ∃ x ) . f x ”, etc. , but the most general form of their combinations”
The fundamental building blocks of logic are not specific operators like 'or' or 'there exists', but rather the general pattern that governs all such combinations.
This points to Wittgenstein's idea of a single general form of proposition underlying all logical expressions.
