Carl Cohen – författare

Rendered from the 11th Edition of Copi/Cohen, Introduction to Logic, the most respected introductory logic book on the market, this concise version presents a simplified yet rigorous introduction to the study of logic. It covers all major topics and approaches, using a three-part organization that outlines specific topics under logic and language, deduction, and induction. For individuals intrigued by the formal study of logic.

No state . . . shall deny to any person within its jurisdiction the equal protection of the laws."" So says the Equal Protection Clause of the U.S. Constitution, a document held dear by Carl Cohen, a professor of philosophy and longtime champion of civil liberties who has devoted most of his adult life to the University of Michigan. So when Cohen discovered, after encountering some resistance, how his school, in its admirable wish to increase minority enrollment, was actually practicing a form of racial discrimination--calling it ""affirmative action""--he found himself at odds with his longtime allies and colleagues in an effort to defend the equal treatment of the races at his university. In A Conflict of Principles Cohen tells the story of what happened at Michigan, how racial preferences were devised and implemented there, and what was at stake in the heated and divisive controversy that ensued. He gives voice to the judicious and seldom heard liberal argument against affirmative action in college admission policies. In the early 1970s, as a member of the Board of Directors of the American Civil Liberties Union, Cohen vigorously supported programs devised to encourage the recruitment of minorities in colleges, and in private employment. But some of these efforts gave deliberate preference to blacks and Hispanics seeking university admission, and this Cohen recognized as a form of racism, however well-meaning. In his book he recounts the fortunes of contested affirmative action programs as they made their way through the legal system to the Supreme Court, beginning with DeFunis v. Odegaard (1974) at the University of Washington Law School, then Bakke v. Regents of the University of California (1978) at the Medical School on the UC Davis campus, and culminating at the University of Michigan in the landmark cases of Grutter v. Bollinger and Gratz v. Bollinger (2003). He recounts his role in the initiation of the Michigan cases, explaining the many arguments against racial preferences in college admissions. He presents a principled case for the resultant amendment to the Michigan constitution, of which he was a prominent advocate, which prohibited preference by race in public employment and public contracting, as well as in public education. An eminently readable personal, consistently fair-minded account of the principles and politics that come into play in the struggles over affirmative action, A Conflict of Principles is a deeply thoughtful and thought-provoking contribution to our national conversation about race.

Do all animals have rights? Is it morally wrong to use mice or dogs in medical research, or rabbits and cows as food? How ought we resolve conflicts between the interests of humans and those of other animals? Philosophical inquiry is essential in addressing such questions; the answers given must have enormous practical importance. Here for the first time in the same volume, the animal rights debate is argued deeply and fully by the two most articulate and influential philosophers representing the opposing camps. Each makes his case in turn to the opposing case. The arguments meet head on: Are we humans morally justified in using animals as we do? A vexed and enduring controversy here receives its deepest and most eloquent exposition.

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 ProofA detailed justification for Indirect Proof treating each of the three distinct ways in which an argument can be validA new section on Conditional Proof, which complements the 19 Rules of Inference and Indirect ProofExplications of proofs of tautologies using both Indirect Proof and Conditional ProofA 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 stepsA new appendix on Step 1 calculations for multiple-line shorter truth tablesA new appendix on unforced truth-value assignments, invalid arguments, and Maxims III-V In addition, a Companion Website will offer:For Students:A Proof CheckerComplete Truth Table ExercisesShorter Truth-Table ExercisesA Truth-Table VideoVenn Diagram Testing of SyllogismsHundreds of True/False and Multiple Choice QuestionsFor Instructors:An Instructor’s ManualA Solutions Manualwww.routledge.com/cw/9781138500860
