Language, Proof and Logic

Language, Proof and Logic serves as a comprehensive introduction to formal logic, combining traditional approaches with modern computational methods. The text includes software tools that allow students to construct and check proofs while learning fundamental concepts. The book progresses from basic propositional logic through first-order logic, teaching both the theory and practical applications through exercises and examples. Students learn to translate English sentences into logical notation and develop skills in formal reasoning and proof construction. Each chapter builds upon previous material, incorporating truth tables, formal proofs, Boolean methods, and predicate logic. The accompanying software programs - Tarski's World, Fitch, and Boole - provide interactive platforms for students to practice concepts. The text demonstrates the connection between language and logical reasoning, emphasizing how formal methods enhance precision in argumentation and analysis. This approach bridges theoretical foundations with practical applications in computer science and mathematics.

Students report this textbook helps build a strong foundation in formal logic through its gradual progression and interactive software components. Many appreciate how it connects natural language to formal logic concepts. Liked: - Clear explanations of complex topics - Practical exercises with immediate feedback - Software tools for checking work - Step-by-step approach to proofs Disliked: - Software installation issues and compatibility problems - High price ($75+) - Some exercises lack detailed solutions - Technical glitches with submission system - Steep learning curve in later chapters One student noted: "The software caught my mistakes and helped me understand where I went wrong." Another commented: "Later chapters on quantifiers become much more difficult with minimal guidance." Ratings: Goodreads: 4.0/5 (146 ratings) Amazon: 3.9/5 (168 ratings) - 5 stars: 52% - 1 star: 16% (mostly software complaints) Many negative reviews focus on technical issues rather than content quality.
