Lectures on Mathematical Logic Volume II

In this volume logic starts from the observation that in everyday arguments as brought forward by say a lawyer statements are transformed linguistically connecting them in formal ways irrespective of their contents. Understanding such arguments as deductive situations or sequents in the technical terminology the transformations between them can be expressed as logical rules. The book concludes with the algorithms producing the results of Gentzen's midsequent theorem and Herbrand's theorem for prenex formulas.
