For more than six decades, and for thousands of students, Introduction to Logic has been the gold standard in introductory logic texts. In this fifteenth edition, Carl Cohen and Victor Rodych update Irving M. Copi’s classic text, improving on its many strengths and introducing new and helpful material that will greatly assist both students and instructors. In particular, chapters 1, 8, and 9 have been greatly enhanced without disturbing the book’s clear and gradual pedagogical approach. Specifically: 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. 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 1 calculations for multiple-line shorter truth tables A new appendix on unforced truth-value assignments, invalid arguments, and Maxims III-V. In addition, a Companion Website will offer: for Students: A Proof Checker Complete Truth Table Exercises Shorter Truth-Table Exercises A Truth-Table Video Venn Diagram Testing of Syllogisms Hundreds of True/False and Multiple Choice Questions for Instructors: An Instructor’s Manual A Solutions Manual www.routledge.com/cw/9781138500860

Victor Erlich was born in 1914, at the threshold of what the great Russian poet Anna Akhmatova called "the real twentieth century," in Petrograd, a place indelibly marked by that century's violent dislocations and upheavals. His story, begun on the eve of the First World War and taking him through Russia, Poland, Lithuania, Germany, and the U. S. Army, is in many ways a memoir of that "real twentieth century," reflecting its lethal nature and shaped by the "fearful symmetry" of the age of totalitarianism. To read about Erlich's life growing up at the intersection of the century's darkest currents is to experience history firsthand from the Russian Revolution to the end of the Second World War--and to know what it truly is to be a child of the century. Throughout, despite the darkness, even the horror, of much of what he describes, the author maintains the beguiling tone and the warm manner of one who has reached the new millennium with rare and hard-won insight into the human comedy of his time.

A New York Review Books Original Victor Serge is one of the great men of the 20th century —and one of its great writers too. He was an anarchist, an agitator, a revolutionary, an exile, a historian of his times, as well as a brilliant novelist, and in Memoirs of a Revolutionary he devotes all his passion and genius to describing this extraordinary—and exemplary—career. Serge tells of his upbringing among exiles and conspirators, of his involvement with the notorious Bonnot Gang and his years in prison, of his role in the Russian Revolution, and of the Revolution’s collapse into despotism and terror. Expelled from the Soviet Union, Serge went to Paris, where he evaded the KGB and the Nazis before fleeing to Mexico. Memoirs of a Revolutionary recounts a thrilling life on the front lines of history and includes vivid portraits not only of Trotsky, Lenin, and Stalin but of countless other figures who struggled to remake the world. Peter Sedgwick’s fine translation of Memoirs of a Revolutionary was abridged when first published in 1963. This is the first edition in English to present the entirety of Serge’s book.

The author, an anarchist, Bolshevik, and Trotskyite, recounts his political involvement from 1906 to 1941, including exile in Siberia
