This book introduces a novel approach to the analysis and practice of persuasive speaking and writing: heuristic rhetoric. The new method has evolved to fulfil the need at universities, government departments, political organisations, business enterprises and other public institutions for a modern practical alternative to classical rhetoric, which is, in the author's view, no longer capable of giving a complete description of contemporary, predominantly mediatised, forms of public persuasive discourse, whilst other competing disciplines, such as critical discourse analysis or strategic manoeuvring, have not yet produced a set of tools, which have the comprehensive nature and practical orientation of Classical Greek and Roman rhetorical system. The book expounds heuristic rhetoric as an inter-disciplinary method to develop advanced skills of critical and strategic reasoning. Applying a novel set of principles for the strategic analysis of persuasive reasoning in complex rhetorical situations, the method emphasizes preparing and continuously adjusting argumentation according to the demands of unpredictable circumstances.
