4.26 If all true elementary propositions are given, the result is a
complete description of the world. The world is completely described by
giving all elementary propositions, and adding which of them are true and
which false. For n states of affairs, there are possibilities of existence
and non-existence. Of these states of affairs any combination can exist and
the remainder not exist.


4.28 There correspond to these combinations the same number of
possibilities of truth--and falsity--for n elementary propositions.


4.3 Truth-possibilities of elementary propositions mean Possibilities of
existence and non-existence of states of affairs.


4.31 We can represent truth-possibilities by schemata of the following kind
('T' means 'true', 'F' means 'false'; the rows of 'T's' and 'F's' under the
row of elementary propositions symbolize their truth-possibilities in a way
that can easily be understood):


4.4 A proposition is an expression of agreement and disagreement with truth-
possibilities of elementary propositions.


4.41 Truth-possibilities of elementary propositions are the conditions of
the truth and falsity of propositions.
