Tractatus Logico-Philosophicus · Chapter
6.124 explained
Wittgenstein argues that logical propositions describe the scaffolding of the world by presenting it, not by treating of anything.
What happens
Wittgenstein argues that logical propositions describe the scaffolding of the world by presenting it, not by treating of anything. They presuppose that names have meaning and elementary propositions have sense. The fact that certain symbol combinations are tautologies shows something essential about the world. In logic, the nature of necessary signs asserts itself, so that knowing the logical syntax of a sign language yields all logical propositions.
Themes in this chapter

Limits of Language and Thought

Key passages
“The logical propositions describe the scaffolding of the world, or rather they present it.”
Logical propositions do not describe the world in a substantive way; instead, they display the underlying structure that makes description possible.
Wittgenstein distinguishes between describing and presenting, emphasizing the unique role of logic.
“in logic it is not we who express, by means of signs, what we want, but in logic the nature of the essentially necessary signs itself asserts.”
In logic, our intentions do not determine the meaning of signs; rather, the inherent nature of logical signs reveals itself.
This underscores the autonomy of logical syntax and the idea that logical truths are not arbitrary.
