No Squares Are Triangles: An Introduction to University-Level Logic

The answer to the logic student's quest for cheap textbooks and revision aids for logic. Includes an overview of the basics of analyzing arguments, statement logic, fallacies, categorical logic, predicate logic, inductive logic and many other methods for determining the validity of arguments, like truth tables, the Venn Method and the Finite Universe Method.
