Tractatus Logico-Philosophicus · Chapter
4.441 explained
Wittgenstein argues that the truth-functional signs 'T' and 'F' do not correspond to any objects or complexes of objects, just as horizontal and vertical lines or brackets do not.
What happens
Wittgenstein argues that the truth-functional signs 'T' and 'F' do not correspond to any objects or complexes of objects, just as horizontal and vertical lines or brackets do not. He concludes that there are no 'logical objects,' and this applies to all signs that express the same as the truth-functional schemata.

- Logical Atomism
Wittgenstein denies that logical signs like 'T' and 'F' correspond to objects, reinforcing the atomistic view that only elementary propositions picture facts.
- Nonsense and Meaning
The claim that there are no logical objects underscores that logical signs do not carry meaning in the same way as names for objects.
Characters to notice
- Mr. Wittgenstein
Author of the Tractatus, presenting the argument that logical signs do not denote objects.
Key passages
“It is clear that to the complex of the signs “F” and “T” no object (or complex of objects) corresponds; any more than to horizontal and vertical lines or to brackets.”
The truth-value signs 'T' and 'F' do not refer to any objects, just as typographical marks like lines or brackets do not.
Wittgenstein emphasizes that logical constants are not names of objects.
“There are no “logical objects.””
No entities correspond to logical signs.
This is a direct denial of the view that logical constants have referents.
