Abstract
Sir Michael Dummett belongs to a small group of the greatest analytical philosophers of the second half of the 20th century, and presumably it would be no exaggeration to consider him the most prominent and influential British philosopher over the last three decades. He has published numerous articles, not only in the field of philosophy. However, a reader willing to learn his recent views is going to face some problems. Although Dummett’s most extended monograph — The Logical Basis of Metaphysics — being a systematic exposition of his own views, was published relatively not so long ago, large parts of it, presented as The William James Lectures at the Harvard University, originally have even come from 1976. From this earlier material, the reader can hardly separate what Dummett has added when preparing this monograph to publication, at the end of the 1980s.
