Since dialetheism has, in recent years, scrounged its way from being a view easily defeated by the dreaded incredulous stare to being a major (but still sometimes ignored) contender in the contest for an adequate logical account of the semantic and set-theoretic paradoxes (or an adequate logical theory in general), the volume is to be commended merely for its existence. The fact that it contains, not just a number of good philosophers taking this view seriously, but also a lot of seriously good philosophy increases its worth... The volume begins with an...

As a survey of a difficult subject, Beall's introduction is a tour-de-force and should be required reading for anyone interested in true contradictions or the philosophy of logic more generally... once one views dialetheism as a natural companion to other, supposedly more 'traditional' views such as classicism, intuitionism, and gappy logics, one wonders why it has taken so long for such an excellent volume to appear.
