ABSTRACT
This chapter distinguishes between knowledge of things and knowledge of facts. The distinction between determinate and indeterminate knowledge relates only to knowing by description. Acquaintance does not admit of degrees. A demonstrative symbol may be regarded as a logically proper name, since it symbolizes an object with which there is acquaintance, and which is thus immediately given. The chapter shows that a descriptive phrase ascribes characteristics. These characteristics may, or may not, belong to some object. If there is any object to which these characteristics belong, then the descriptive phrase applies to that object, or objects. It is closely related to the traditional distinction between connotation and denotation. The latter pair of terms in the sense in which they have been generally used were introduced into modern logic by J. S. Mill. The denotation of a word is the object, to which the word rightly applies.
