In the first section of this book, Blackburn conducts an analysis of the correspondence, coherence, pragmatic, deflationary, and semantic approaches to truth. Blackburn's sympathies lie with the deflationary approach, which colours his analysis of the second section of the book about the varieties of enquiry.
Overall a good book about epistemology, but a word of warning: this is not some vague, artistic book that explores the oft-uttered stoner question, "what is truth, man?". This is a dry, boring book about epistemology and will only interest the philosophically-inclined reader.
