An inquiry into meaning and truth

The author is concerned above all with language, as he examines the processes of thought, expression and knowledge with mathematical precision. What is the relation between a belief and a sentence in which that belief is expressed? How are we to set about defining 'knowledge' and 'truth' and relating these concepts to our own experience? In answering such questions the author applies the methods of psychology as well as logic. Whilst his answers are often complex -- as, for precision, they must be -- his arguments are at all times both lucid and elegant. [Back cover].
