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 yields a different sense,
and so does its ending with a different stem.)
