Following an introductory chapter exploring why political argument deals in probability and plausibility across interdependent areas of social activity not certainty in individual areas, this book offers a case for independence under six main headings -- the democratic case, the economic case, the social case, the international case, the cultural case and the environmental case. Under each heading, the case is assessed against both the supportive evidence and the hostile evidence, from a variety of sources, concluding with a judgement of where the balance of the evidence points. The book concludes with a selection of populist objections to independence answered by summary rebuttals from the independence file.
