VVhat Sentences "Indicate"

When "truth" and "falsehood" are regarded as applicable to sentences, there are, from the standpoint of theory of knowledge, two kinds of sentences: ( 1) those whose truth or falsehood can be inferred from their syntactical relation to other sentences, (2) those whose truth or falsehood is only derivable from a relation to something that may be called "fact". Molecular and general sentences may, for the moment, be regarded as of the first kind; whether this is strictly true we shall consider at a later stage. The problems with which we are concerned in the present work arise only in regard to sentences of the second kind, for, if we have defined "truth" and "falsehood" for such sentences, the problems that remain belong to syntax or logic, which is not our subject.
