ADVANGEBOOKS - UNDERSTANDING ARGUMENTS: AN INTRODUCTION TO INFORMAL LOGIC, 9E shows readers how to construct arguments in everyday life, using everyday language. In addition, this easy-to-read textbook also devotes three chapters to the formal aspects of logic including forms of argument, as well as propositional, categorical, and quantificational logic. Plus, this edition helps readers apply informal logic to legal, moral, scientific, religious, and philosophical scenarios, too. "With its lucid explanations, penetrating analysis of real-world issues, and its selection of exemplary, timely readings, Understanding Arguments should be required reading in any course whose objectives include improving critical thinking and analytical skills." "This book is a well-crafted and philosophically-infused work. It gets students engaged with the material and genuinely challenges them to think critically. It works particularly well for courses on critical thinking that are aimed at developing students' skills in quantitative reasoning."
