ABSTRACT
Truth and falsehood, in so far as they are public, are attributes of sentences, either in the indicative or in the subjunctive or conditional. In the present chapter, which will consider only the simpler examples of truth, I shall confine myself to sentences in the indicative. In addition to sentences there are some other ways of making public statements, maps, for instance, and graphs. There are also conventional devices for reducing a sentence to one essential word, as is done in telephone books and railway time tables. But for our purposes we may, without any important loss of generality, confine ourselves to fully expressed sentences. And until we have considered logical words, which will be the subject of the next two chapters, we must confine ourselves to sentences in the indicative.
