ABSTRACT
In the first chapter of this part of the book I have set out the most general arguments for the existence of basic statements; the traditional argument that there must be some beliefs that do not owe their justification to others if any beliefs are to be justified and the more recent argument that there must be some sentences which are introduced ostensively and not by correlation with other, antecedently understood, sentences if any are to have factual, descriptive, empirical meaning. In the next two chapters I went on to argue that it did not follow from the existence of basic statements in this very general sense either that such statements must be certain in some special way, since inferred statements may be beyond reasonable doubt and no statements are incorrigible, or that they should be reports of immediate experience.
