<P>In The Uses of Argument (1958), Stephen Toulmin proposed a model for the layout of arguments: claim, data, warrant, qualifier, rebuttal, backing. Since then, Toulmin's model has been appropriated, adapted and
extended by researchers in speech communications, philosophy and artificial intelligence. This book assembles the best contemporary reflection in these fields, extending or challenging Toulmin's ideas in ways that make fresh
contributions to the theory of analysing and evaluating arguments. </P>
