Logic is synonymous with reason, judgment, sense, wisdom, and sanity. Being logical is the ability to create concise and reasoned arguments—arguments that build from given premises, using evidence, to a genuine conclusion. But mastering logical thinking also requires studying and understanding illogical thinking, both to sharpen one’s own skills and to protect against incoherent, or deliberately misleading, reasoning.
Elegant, pithy, and precise, Being Logical breaks logic down to its essentials through clear analysis, accessible examples, and focused insights. D. Q. McInerney covers the sources of illogical thinking, from naïve optimism to narrow-mindedness, before dissecting the various tactics—red herrings, diversions, and simplistic reasoning—the illogical use in place of effective reasoning.
An indispensable guide to using logic to advantage in everyday life, this is a concise, crisply readable book. Written explicitly for the layperson, McInerny’s Being Logical promises to take its place beside Strunk and White’s The Elements of Style as a classic of lucid, invaluable advice.
Praise for Being Logical
“Highly readable . . . D. Q. McInerny offers an introduction to symbolic logic in plain English, so you can finally be clear on what is deductive reasoning and what is inductive. And you’ll see how deductive arguments are constructed.”—Detroit Free Press
“McInerny’s explanatory outline of sound thinking will be eminently beneficial to expository writers, debaters, and public speakers.”—Booklist
“Given the shortage of logical thinking,
And the fact that mankind is adrift, if not sinking,
It is vital that all of us learn to think straight.
And this small book by D.Q. McInerny is great.
It follows therefore since we so badly need it,
Everybody should not only but it, but read it.”
—Charles Osgood

"Poincaré's was the last man to take practically all mathematics, both pure and applied as his province. Few mathematicians have had the breadth of philosophic vision that Poincaré's had, and none is his superior in the gift of clear exposition." — Men of Mathematics, Eric Temple Bell, Professor of Mathematics, University of Cambridge
The antidote to fuzzy thinking, with furry animals!
Have you read (or stumbled into) one too many irrational online debates? Ali Almossawi certainly had, so he wrote An Illustrated Book of Bad Arguments! This handy guide is here to bring the internet age a much-needed dose of old-school logic (really old-school, a la Aristotle).
Here are cogent explanations of the straw man fallacy, the slippery slope argument, the ad hominem attack, and other common attempts at reasoning that actually fall short—plus a beautifully drawn menagerie of animals who (adorably) commit every logical faux pas. Rabbit thinks a strange light in the sky must be a UFO because no one can prove otherwise (the appeal to ignorance). And Lion doesn’t believe that gas emissions harm the planet because, if that were true, he wouldn’t like the result (the argument from consequences).
Once you learn to recognize these abuses of reason, they start to crop up everywhere from congressional debate to YouTube comments—which makes this geek-chic book a must for anyone in the habit of holding opinions.
Utilizing real questions submitted to his popular website ReasonableFaith.org, Dr. Craig models well-reasoned, skillful, and biblically informed interaction with his inquirers. A Reasonable Response goes beyond merely talking about apologetics; it shows it in action. With cowriter Joseph E. Gorra, this book also offers advice about envisioning and practicing the ministry of answering people’s questions through the local church, workplace, and in online environments.
Whether you're struggling to respond to tough objections or looking for answers to your own intellectual questions, A Reasonable Response will equip you with sound reasoning and biblical truth.
This major new edition features many topics not covered in the original, including graphical models, random forests, ensemble methods, least angle regression & path algorithms for the lasso, non-negative matrix factorization, and spectral clustering. There is also a chapter on methods for ``wide'' data (p bigger than n), including multiple testing and false discovery rates.
Trevor Hastie, Robert Tibshirani, and Jerome Friedman are professors of statistics at Stanford University. They are prominent researchers in this area: Hastie and Tibshirani developed generalized additive models and wrote a popular book of that title. Hastie co-developed much of the statistical modeling software and environment in R/S-PLUS and invented principal curves and surfaces. Tibshirani proposed the lasso and is co-author of the very successful An Introduction to the Bootstrap. Friedman is the co-inventor of many data-mining tools including CART, MARS, projection pursuit and gradient boosting.
In How We Think, Dewey shares his views on the educator’s role in training students to think well. Basing his assertions on the belief that knowledge is strictly relative to human interaction with the world, he considers the need for thought training, its use of natural resources, and its place in school conditions; inductive and deductive reasoning, interpreting facts, and concrete and abstract thinking; the functions of activity, language, and observation in thought training; and many other subjects.
John Dewey’s influence on American education and philosophy is incalculable. This volume, as fresh and inspirational today as it was upon its initial publication a century ago, is essential for anyone active in the field of teaching or about to embark on a career in education.
In the daily battle for our hearts and minds--not to mention our hard-earned cash--the truth is usually the first casualty. It's time we learned how to see through the rhetoric, faulty reasoning, and misinformation that we're subjected to from morning to night by talk-radio hosts, op-ed columnists, advertisers, self-help gurus, business "thinkers," and, of course, politicians. And no one is better equipped to show us how than award-winning philosopher Jamie Whyte.
In Crimes Against Logic Whyte take us on a fast-paced, ruthlessly funny romp through the mulligan stew of can, folderol, and bogus logic served up in the media, at the office, and even in your own home. Applying his laserlike wit to dozens of timely examples, Whyte cuts through the haze of facts, figures, and double-talk and gets at the real truth behind what they're telling us.
"An incisive philosopher."

In 1931 the mathematical logician Kurt Godel published a revolutionary paper that challenged certain basic assumptions underpinning mathematics and logic. A colleague of physicist Albert Einstein, his theorem proved that mathematics was partly based on propositions not provable within the mathematical system. The importance of Godel's Proof rests upon its radical implications and has echoed throughout many fields, from maths to science to philosophy, computer design, artificial intelligence, even religion and psychology. While others such as Douglas Hofstadter and Roger Penrose have published bestsellers based on Godel’s theorem, this is the first book to present a readable explanation to both scholars and non-specialists alike. A gripping combination of science and accessibility, Godel’s Proof by Nagel and Newman is for both mathematicians and the idly curious, offering those with a taste for logic and philosophy the chance to satisfy their intellectual curiosity.
Kurt Godel (1906 – 1978) Born in Brunn, he was a colleague of physicist Albert Einstein and professor at the Institute for Advanced Study in Princeton, N.J.
An instructor’s website is available with solutions to all the exercises in the text, including the many new exercises which have been added to this new edition.
He identifies with devastating examples all the most common fallacies popularly used in argument. We all like to think of ourselves as clear-headed and logical - but all readers will find in this book fallacies of which they themselves are guilty. The author shows you how to simultaneously strengthen your own thinking and identify the weaknesses in other people arguments. And, more mischievously, Pirie also shows how to be deliberately illogical - and get away with it. This book will make you maddeningly smart: your family, friends and opponents will all wish that you had never read it.
Publisher's warning: In the wrong hands this book is dangerous. We recommend that you arm yourself with it whilst keeping out of the hands of others. Only buy this book as a gift if you are sure that you can trust the recipient.

With real life examples, advice on graduate school entrance exams and an expanded companion website packed with additional exercises, an answer key and help with real life examples, this easy-to-follow introduction is a complete beginner's tool set to good reasoning, analyzing and arguing. Ideal for students in basic reasoning courses and students preparing for graduate school.
Some philosophers have hypothesized a realm of individual essences that stand as proxies for all merely possible beings. Others have argued that we are committed to the necessary existence of everything that does or might exist. In contrast, Mere Possibilities shows how we can make sense of ordinary beliefs about what might and must exist without making counterintuitive metaphysical commitments. The book also sheds new light on the nature of metaphysical theorizing by exploring the interaction of semantic and metaphysical issues, the connections between different metaphysical issues, and the nature of ontological commitment.
In this third edition, Anne Thomson has updated and revised the book to include fresh and topical examples which will guide students through the processes of critical reasoning in a clear and engaging way. In addition, two new chapters on evaluating the credibility of evidence and decision making and dilemmas will fully equip students to reason well. By the end of the book students should be able to:
identify flaws in arguments analyze the reasoning in newspaper articles, books and speeches assess the credibilty of evidence and authorities make sound decisions and solve dilemmas approach any topic with the ability to reason and think critically.An estimated 60 percent of scientists are atheists or agnostics. However, the skeptical world view has been given little currency even in advanced societies, because of a cultural prohibition against the criticism of religion. At the same time, science has become increasingly narrow and specialized so that few people can draw on its broader intellectual and cultural implications. Skepticism and Humanism attempts to meet this need. It defends skepticism as a method for developing reliable knowledge by using scientific inquiry and reason to test all claims to truth. It also defends scientific naturalism-an evolutionary view of nature, life, and the human species. Kurtz sees the dominant religious doctrines as drawn from an agricultural/nomadic past, and emphasizes the need for a new outlook applicable to the postindustrial information age. At the same time, he rejects postmodernism for abandoning science and embracing a form of nihilism.
There can be no doubt that as a new global civilization emerges, scientific naturalism, rationalism, and secular humanism have something significant to say about the meaning of life. Skepticism and Humanism shows how they can to foster democratic values and social prosperity. The book will be important for philosophers, scientists, and all those concerned with contemporary issues.
Paul Kurtz taught at Trinity College, Vassar College, and State University of New York at Buffalo. He is founder of Prometheus Books, a major publisher of philosophical works. He is the author of some thirty books including Toward a New Enlightenment (available from Transaction) Humanist Manifesto 2000, and A Secular Humanist Declaration. He is chairman of the Committee for the Scientific Investigation of Claims of the Paranormal, and editor-in-chief of Free Inquiry magazine.
He sat on a chair in the middle of the room, with some of the class sitting in chairs, some on the floor. He never used notes. He paused frequently, sometimes for several minutes, while he puzzled out a problem. He often asked his listeners questions and reacted to their replies. Many meetings were largely conversation.
These lectures were attended by, among others, D. A. T. Gasking, J. N. Findlay, Stephen Toulmin, Alan Turing, G. H. von Wright, R. G. Bosanquet, Norman Malcolm, Rush Rhees, and Yorick Smythies. Notes taken by these last four are the basis for the thirty-one lectures in this book.
The lectures covered such topics as the nature of mathematics, the distinctions between mathematical and everyday languages, the truth of mathematical propositions, consistency and contradiction in formal systems, the logicism of Frege and Russell, Platonism, identity, negation, and necessary truth. The mathematical examples used are nearly always elementary.
The syllogism is Aristotle’s most famous contribution to logic and because any valid argument must take the form of a syllogism, his work in analyzing syllogisms provides a basis for analyzing all arguments and prove rigorously whether they are true or false, valid or invalid.
Based on the same study of syllogisms and their practical application to life, the Author proposes an analysis of relationships in modern times using deductive reasoning. Therefore, the book answers the most common questions women have regarding men, combining a total of 69 syllogisms about attraction, behavior, communication, relationships and love.
