The new edition of a comprehensive and rigorous but concise introduction to symbolic logic. Logic Primer offers a comprehensive and rigorous introduction to symbolic logic, providing concise definitions of key concepts, illustrative examples, and exercises. After presenting the definitions of validity and soundness, the book goes on to introduce a formal language, proof theory, and formal semantics for sentential logic (chapters 1–3) and for first-order predicate logic (chapters 4–6) with identity (chapter 7). For this third edition, the material has been reorganized from four chapters into seven, increasing the modularity of the text and enabling teachers to choose alternative paths through the book. New exercises have been added, and all exercises are now arranged to support students moving from easier to harder problems. Its spare and elegant treatment makes Logic Primer unique among textbooks. It presents the material with minimal chattiness, allowing students to proceed more directly from topic to topic and leaving instructors free to cover the subject matter in the way that best suits their students. The book includes more than thirty exercise sets, with answers to many of them provided in an appendix. The book’s website allows students to enter and check proofs, truth tables, and other exercises interactively.

Logic Primer presents a rigorous introduction to natural deduction systems of sentential and first-order logic. Logic Primer presents a rigorous introduction to natural deduction systems of sentential and first-order logic. The text is designed to foster the student-instructor relationship. The key concepts are laid out in concise definitions and comments, with the expectation that the instructor will elaborate upon them. New to the second edition is the addition of material on the logic of identity in chapters 3 and 4. An innovative interactive Web site, consisting of a "Logic Daemon" and a "Quizmaster," encourages students to formulate their own proofs and links them to appropriate explanations in the book.

Logic Primer is a classroom and laboratory for students engaged in the study of logic. From the writings of Dr. Gordon H. Clark, logic is defined as "the science of necessary inference." The Primer divides into seven chapters. Chapter 1 defines necessary basic terms to enable the reader to begin the investigation. Chapter 2 describes the four standard propositional forms, their formal properties, and methods for translating nonstandard into standard form propositions. Chapter 3 discusses immediate inferences. Chapter 4 examines the syllogism by describing its elements, valid moods and figures, and methods for determining validity. Chapter 5 introduces the student to additional valid argument forms and two important formal fallacies. Chapter 6 covers truth-table analyses of extended arguments. Chapter 7 examines informal fallacies, their classification, and the need for strict definition as a means for avoiding informal fallacies. Each chapter ends with questions for review and exercises to test the student's progress. Exercises/Answers are provided in an Appendix. A glossary of terms with corresponding chapter numbers serves as an index.

Formal logic provides us with a powerful set of techniques for criticizing some arguments and showing others to be valid. These techniques are relevant to all of us with an interest in being skilful and accurate reasoners. In this highly accessible book, Peter Smith presents a guide to the fundamental aims and basic elements of formal logic. He introduces the reader to the languages of propositional and predicate logic, and then develops formal systems for evaluating arguments translated into these languages, concentrating on the easily comprehensible 'tree' method. His discussion is richly illustrated with worked examples and exercises. A distinctive feature is that, alongside the formal work, there is illuminating philosophical commentary. This book will make an ideal text for a first logic course, and will provide a firm basis for further work in formal and philosophical logic.

Students new to Latin will want to begin here, as Martha Wilson sets up the framework for learning Latin from a classical, Trivium-based approach. Latin Primer I focuses primarily on the memorization of vocabulary and noun and verb endings (declensions and conjugations), and basic grammar is touched on. This workbook is intended for one year's worth of study. Recommended for grades 3 and up. Classical pronunciation. Consumable. 27 lessons.
