Over the last two decades, the field of artificial intelligence has experienced a separation into two schools that hold opposite opinions on how uncertainty should be treated. This separation is the result of a debate that began at the end of the 1960 s when AI first faced the problem of building machines required to make decisions and act in the real world. This debate witnessed the contraposition between the mainstream school, which relied on probability for handling uncertainty, and an alternative school, which criticized the adequacy of probability in AI applications and developed alternative formalisms. The debate has focused on the technical aspects of the criticisms raised against probability while neglecting an important element of contrast. This element is of an epistemological nature, and is therefore exquisitely philosophical. In this book, the historical context in which the debate on probability developed is presented and the key components of the technical criticisms therein are illustrated. By referring to the original texts, the epistemological element that has been neglected in the debate is analyzed in detail. Through a philosophical analysis of the epistemological element it is argued that this element is metaphysical in Popper s sense. It is shown that this element cannot be tested nor possibly disproved on the basis of experience and is therefore extra-scientific. Ii is established that a philosophical analysis is now compelling in order to both solve the problematic division that characterizes the uncertainty field and to secure the foundations of the field itself.

In this bestselling timeless classic, Peter Gzowski recounts the 1980-81 season he spent travelling around the NHL circuit with the Edmonton Oilers. These were the days when the young Oilers, led by a teenaged Wayne Gretzky, were poised on the edge of greatness, and about to blaze their way into the record books and the consciousness of a nation. While the story of the early Oilers embodies the book, The Game of Our Lives is much more than a retelling of one season in the life of an NHL team. Unlike any book ever written in the annals of hockey, Gzowski beautifully weaves together the anatomy of a modern NHL team with the magnificent history of the game to create one of the best books about hockey in Canada. Here are the great teams and the great players through the ages—Morenz, Richard, Howe, Orr, Hull—the men whose rare and indefinable genius on the ice exemplified the speed, grit and innovation of the game. The Game of Our Lives is the best book on the Canadian passion for hockey; a wondrously perceptive account of the hold the game has on Canadians. —Jack Granatstein, The National Post

Hockey Night in Canada has reached a great age (and for television, practically an immortal one) because it made itself into something that Canada couldn't live without. It is this surge of emotion that connected us all each week, and which connects us through the years to now. Hockey Night in Canada didn't just aim a camera at a game and observe what happened-it actively gave the country a prism through which it could see itself and its evolving diversity. We look where the eye of Hockey Night in Canada looks, and it looks at us. We remember what it remembers. We feel what it feels. That is the dynamic that has made the show much more than a long-lived TV success; it is a cultural juggernaut. Ask fans where they saw their first hockey game, and chances are it was on Hockey Night in Canada. Ask the players-male or female-what first got them into the rink, and the answer will be the same: they wanted to be like the players on Hockey Night in Canada.
