Logic Primer

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." After the Preface and Introduction, the Primer divides into seven chapters. Chapter 1 Definitions examines necessary basic terms to enable the reader to begin the investigation. Chapter 2 Propositions describes the four standard propositional forms, their formal properties, and methods for translating nonstandard into standard form propositions. Chapter 3 Immediate Inference discusses a variety of traditional logic inferences. Chapter 4 Syllogism examines and describes its elements, valid moods and figures, and methods for determining validity. Chapter 5 Additional Argument Forms introduces the student to other valid argument forms and two important formal fallacies. Chapter 6 Truth Tables covers truth-table construction and analyses of extended arguments. Chapter 7 Informal Fallacies examines 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. A Glossary of terms with corresponding chapter numbers serves as an index. Two Appendices end the project: Appendix A: Symbolic Logic and Appendix B: Subalternation.
