bare signs (spoken or written, etc.) of the proposition as a projection of the possible state of affairs.

The method of projection is the thinking of the sense of the proposition.

3.12

The sign through which we express the thought I call the propositional sign. And the proposition is the propositional sign in its projective relation to the world.

3.13

To the proposition belongs everything which belongs to the projection; but not what is projected.

Therefore, the possibility of what is projected, but not this itself.

In the proposition, therefore, its sense is not yet contained, but the possibility of expressing it.

(“The content of the proposition” means the content of the significant proposition.)

In the proposition the form of its sense is contained, but not its content.

3.14

The propositional sign consists in the fact that its elements, the words, are combined in it in a definite way.

The propositional sign is a fact.

3.141

The proposition is not a mixture of words. Just as a musical theme is not a mixture of tones.

The proposition is articulate.

3.142

Only facts can express a sense, a class of names cannot.

3.143

That the propositional sign is a fact is concealed by the ordinary form of expression in writing or print.

tion (spoken or written, etc.) as a projection of a possible situation.

The method of projection is to think of the sense of the proposition.

I call the sign with which we express a thought a propositional sign. And a proposition is a propositional sign in its projective relation to the world.

A proposition includes all that the projection includes, but not what is projected.

Therefore, though what is projected is not itself included, its possibility is.

A proposition, therefore, does not actually contain its sense, but does contain the possibility of expressing it.

(“The content of a proposition” means the content of a proposition that has sense.)

A proposition contains the form, but not the content, of its sense.

What constitutes a propositional sign is that in it its elements (the words) stand in a determinate relation to one another.

A propositional sign is a fact.

A proposition is not a blend of words. Just as a theme in music is not a blend of notes.

A proposition is articulate.

Only facts can express a sense, a set of names cannot.

Although a propositional sign is a fact, this is obscured by the usual form of expression in writing or print.
