scribe reality completely.
A proposition is a description of a state of affairs. Just as a
description of an object describes it by giving its external properties,
so a proposition describes reality by its internal properties. A
proposition constructs a world with the help of a logical scaffolding,
so that one can actually see from the proposition how everything
stands logically if it is true. One can draw inferences from a false
proposition.

4.024 To understand a proposition means to know what is the case if it
is true. (One can understand it, therefore, without knowing whether it
is true.) It is understood by anyone who understands its constituents.

4.025 When translating one language into another, we do not proceed by
translating each proposition of the one into a proposition of the other,
but merely by translating the constituents of propositions. (And the
dictionary translates not only substantives, but also verbs, adjectives,
and conjunctions, etc.; and it treats them all in the same way.)

4.026 The meanings of simple signs (words) must be explained to us if
we are to understand them. With propositions, however, we make ourselves
understood.

4.027 It belongs to the essence of a proposition that it should be able
to communicate a new sense to us.

4.03 A proposition must use old expressions to communicate a new
sense. A proposition communicates a situation to us, and so it must be
essentially connected with the situation. And the connexion is precisely
that it is its logical picture. A proposition states something only in
so far as it is a picture.

4.031 In a proposition a situation is, as it were, constructed by way of
experiment. Instead of, 'This proposition has such and such a sense, we
can simply say, 'This proposition represents such and such a situation'.

4.0311 One name stands for one thing, another for another thing, and
they are combined with one another. In this way the whole group--like a
tableau vivant--presents a state of affairs.

4.0312 The possibility of propositions is based on the principle that
objects have signs as their representatives. My fundamental idea is that
the 'logical constants' are not representatives; that there can be no
representatives of the logic of facts.

4.032 It is only in so far as a proposition is logically articulated
that it is a picture of a situation. (Even the proposition, 'Ambulo',
is composite: for its stem with a different ending y
