"Suppose your friend – or your student, or yourself – knows a little logic and a little philosophy. If you wish that person to gain an early appreciation of philosophical logic, then this book is a perfect gift – or assignment, or purchase. Written by outstanding philosophical logicians, its clear and authoritative chapters guide the reader directly into the heart of each topic. There are enough details to create genuine understanding, but not so many as to intimidate. The term 'guide' is exactly the right word for this splendid book." Nuel Belnap, University of Pittsburgh "This is an excellent collection of articles covering the main areas of philosophical logic, written by front-line, internationally known researchers in the field. It should be available in every serious library." Dov Gabbay, King's College, London "This volume on philosophical logic is a welcome and manageable resource. The editor is to be congratulated both on his choice of material and on his choice of collaborators. The result is a well-balanced mix of authoritative overviews of classical mathematical logic and up-to-date accounts of topics in linguistics and computer science." Krister Segerberg, Uppsala University "These twenty chapters cover the areas of logic of greatest interest to philosophers, and also to computer scientists, linguists, and cognitive scientists. They are written by world-class authorities in their fields and give comprehensive and definitive introductions to their subjects." Ernie Lepore, Rutgers University "For those interested in the philosophy of logic an excellent place to turn would be The Blackwell Guide to Philosophical Logic edited by Lou Goble. The book consists of 20 specially written essays by distinguished figures in the field, each with an editor's introduction." Times higher Education Supplement "The intended readership is philosophers and logicians, but there is much that will be of interest to computer scientists, cognative scientists and theoretical linguists. The Book is accessible to non-experts and experts will find much substance in the essays." Studia Logica
