We Download free Introduction to logic by Irving Copi & Carl Cohen 15th edition solutions manual & exercise answers pdf | solution & answer key explore the difficulties encountered in everyday uses of language, and the different functions of language. We explain the nature and functions of definitions in ordinary discourse, and then identify and exhibit the many informal fallacies that are commonly encountered. In Part II the methods of deductive reasoning are presented and analyzed. Here we first give an account of syllogistic logic, and then introduce the more powerful notation and techniques of modem symbolic logic.

Finally, in Part III, the techniques of inductive logic are presented, beginning with the appraisal of simple analogical arguments and proceeding to an analysis of causal reasoning, and the canons of scientific method. We conclude with an account of alternative theories of probability, and the uses of the theorems in the elementary calculus of probability. In this edition of Introduction to Logic, Chapters I, 8, and 9 have been greatly enhanced, without disturbing the book’s clear and gradual pedagogical approach.
New to This Edition
• Chapter 1 now uses a simpler and better definition of ‘deductive validity,” which enhances the rest of the book (especially Chapters 1 and 8-10, and their new components).

Chapter 8 now has:

• Simpler definitions of “simple statement” and ‘compound statement” • More, and more detailed, examples of the Complete Truth-Table Method • An updated section on ‘The Three “Laws of Thought”; reflecting the central-ity of the Principles of Excluded Middle and Non-Contradiction in Classical Symbolic Logic, and indicating some of the extensions and alternatives to Classical Symbolic Logic that have emerged over the last 100 years.

• Chapter 9 now has: • A detailed, step-by-step account of the Shorter Truth-Table Method (with detailed step-by-step examples for conclusions of different types) • A more complete and detailed account of Indirect Proof • A detailed justification for Indirect Proof treating each of the three distinct ways in which an argument can be valid • A new section on Conditional Proof, which complements the 19 Rules of Inference and Indirect Proof • Explications of proofs of tautologies using both Indirect Proof and Conditional Proof • A new section at the end of the chapter explaining the important difference between sound and demonstrative arguments.

• The Appendices now include: • A new appendix on making the Shorter Truth-Table Technique (STTT) more efficient by selecting the most efficient sequence of STTT steps • A new appendix on Step I calculations for multiple-line shorter truth tables • A new appendix on unforced truth-value assignments, invalid arguments, and Maxims III-V.

Introduction to Logic In all of Its editions has been

rich with illustrative materials and exercises taken from events and controversies in real life, from history and some classical sources, but mainly from contemporary periodicals and books. We take pride in the fact that, as our reviewers have noted, those studying Introduction to Logic are Inescapably introduced to a very wide range of intellectual concerns and thus learn much more than logic. Exhibiting arguments and theories (good and bad) by illustrating them with genuine controversies In the world of college students, rather than with illustrations artificially devised for the purpose, has been our continuing concern.

Logical theory is most fully grasped when it is vividly applied to contemporary human affairs. In the selection of illustrations and exercises, especially those concerning lively issues in the first years of the twenty-first century, we seek scrupulously to avoid partisanship. On all sides of controversial issues, good arguments, and bad ones, may appear. Support for one view or another in current controversy is not our proper business; the understanding and analysis of arguments is. In all editions of Introduction to Logic we strove to achieve that combination of accuracy, clarity, and penetration that has always been our objective.
