„Shafer... and Vovk... explain how probability can be based on game theory rather than measure theory, and how doing so allows it to be used in finance with out a lot of distracting an confusing assumptions about randomness.“ (Reference & Research Book News, November 2001)
„.... an interesting new mathematical and philosophical framework for probability...“ (Zentralblatt Math, Vol.985, No.10, 2002)
„... a creative, entertaining and imaginative book...“ (Short Book Reviews, August 2002)
„The first half of this truly original book introduces a novel approach to probability, founded on game theory rather than measure theory. In an admirably clear, scholarly and engaging manner, it traces its historical antecedents, expounds its advantages, develops its technicalities, and addresses its philosophical implications. The second half goes on to do the same for financial modelling. This is a book that should utterly change the way we think about its two topics.“
