Bertrand Russell is concerned with the foundations of knowledge which he approaches first through language. 'Meaning', as applied to words, is shown to be different for words of different kinds: object-words, proper names, logical words and dictionary words. For a sentence we have to consider the way that it expresses something of the nature of an assertion, a denial, an imperative, a desire, or a question.
We can understand what it expresses if we know the meaning of its several words and the rules of syntax. From this Russell passes to a discussion of a belief and a sentence in which it is expressed. 'Knowledge' and 'truth' involve the relationship of truth to experience and Russell considers whether we can know that there are unknowable truths.
