William Hughes's Critical Thinking, revised and updated by Jonathan Lavery, is a comprehensive and accessible introduction to the essential skills required to make strong arguments. Hughes and Lavery give a thorough treatment of such traditional topics as deductive and inductive reasoning, logical fallacies, the importance of inference, how to recognize and avoid ambiguity, and how to assess what is or is not relevant to an argument. The authors also cover less traditional topics such as special concerns to keep in mind when reasoning about ethical matters, and how the nature of a language can affect the structure of an argument. In addition to covering basic concepts for analyzing and assessing arguments, the text also has two chapters that are designed to help students write argumentative essays. Last but not least, Critical Thinking includes a selection of logical paradoxes and puzzles that are as entertaining as they are enlightening. For the fifth edition particular attention has been paid to the needs of Canadian students and instructors.
