The New York Times best-selling author of The Year of Living Biblically goes on a journey to understand the enduring power of puzzles: why we love them, what they do to our brains, and how they can improve our world.

Almost as soon as it appeared, the crossword puzzle became indispensable to our lives. Invented practically by accident in 1913, when a newspaper editor at the New York World was casting around for something to fill empty column space, it became a roaring commercial success almost overnight. Ever since then, the humble puzzle has been an essential ingredient of any newspaper worth its salt. But why, exactly, are the crossword’s satisfactions so sweet.

In a culture increasingly indifferent or even hostile to Christian truth, followers of Christ need to be equipped to communicate with those who do not speak their language or accept their source of authority. In Tactics, 10th Anniversary Edition, Gregory Koukl demonstrates how to artfully regain control of conversations, keeping them moving forward in constructive ways through thoughtful diplomacy. Step-by-step, you'll learn the tactics of good persuasion and defense, how to identify the tactics of your opponent, and how to build your case, patiently and practically.

This in-depth discussion of New Testament scholarship and the challenges of history as a whole proposes Bayes's Theorem, which deals with probabilities under conditions of uncertainty, as a solution to the problem of establishing reliable historical criteria. The author demonstrates that valid historical methods - not only in the study of Christian origins but in any historical study - can be described by, and reduced to, the logic of Bayes's Theorem. Conversely, he argues that any method that cannot be reduced to this theorem is invalid and should be abandoned.

Taught by award-winning Professor Patrick Grim of the State University of New York at Stony Brook, The Philosopher’s Toolkit: How to Be the Most Rational Person in Any Room arms you against the perils of bad thinking and supplies you with an arsenal of strategies to help you be more creative, logical, inventive, realistic, and rational in all aspects of your daily life.

This remarkable work offers an analytical exploration of the nature of divine eternity and God's relationship to time. 

Over a storied career, Daniel C. Dennett has engaged questions about science and the workings of the mind. His answers have combined rigorous argument with strong empirical grounding. And a lot of fun. Intuition Pumps and Other Tools for Thinking offers seventy-seven of Dennett’s most successful “imagination-extenders and focus-holders” meant to guide you through some of life’s most treacherous subject matter: evolution, meaning, mind, and free will.

This audiobook is a long-awaited major statement by a pre-eminent analytic philosopher, Alvin Plantinga, on one of our biggest debates - the compatibility of science and religion. The last twenty years has seen a cottage industry of books on this divide, but with little consensus emerging. Plantinga, as a top philosopher but also a proponent of the rationality of religious belief, has a unique contribution to make. His theme in this short book is that the conflict between science and theistic religion is actually superficial, and that at a deeper level they are in concord.

In There Is a God, one of the world's preeminent atheists discloses how his commitment to "follow the argument wherever it leads" led him to a belief in God as Creator. This is a compelling and refreshingly open-minded argument that will forever change the atheism debate.

The Problems of Philosophy discusses Bertrand Russell's views on philosophy and the problems that arise in the field. Russell's views focus on knowledge rather than the metaphysical realm of philosophy. The Problems with Philosophy revolves around the central question that Russell asks in his opening line of Chapter 1 - Is there any knowledge in the world which is so certain that no reasonable man could doubt it?

What does it actually mean to be rational? Not Hollywood-style "rational", where you forsake all human feeling to embrace Cold Hard Logic, but where you make good decisions, even when it's hard; where you reason well, even in the face of massive uncertainty; where you recognize and make full use of your fuzzy intuitions and emotions, rather than trying to discard them. In Rationality: From AI to Zombies, Eliezer Yudkowsky explains the science underlying human irrationality with a mix of fables, argumentative essays, and personal vignettes.

Bertrand Russell wrote that mathematics can exalt "as surely as poetry". This is especially true of one equation: ei(pi) + 1 = 0, the brainchild of Leonhard Euler, the Mozart of mathematics. More than two centuries after Euler's death, it is still regarded as a conceptual diamond of unsurpassed beauty. Called Euler's identity, or God's equation, it includes just five numbers but represents an astonishing revelation of hidden connections.

With a scientific eye and an empathetic heart, the authors turn conventional perceptions about atheism on their head. They show that atheism need not be reactionary (against religion and God), but rather that it can offer a clear set of constructive principles to live by, which establish atheism as a positive worldview.

In this audiobook, David Gunkel offers a provocative attempt to think about what has been previously regarded as unthinkable: whether and to what extent robots and other technological artifacts of our own making can and should have any claim to moral and legal standing.

Rigid adherence to scientism - as opposed to a healthy respect for science - is all too prevalent in our world today. Rather than leading to a deeper understanding of our universe, this worldview actually undermines real science and marginalizes morality and religion. In this book, celebrated philosopher J. P. Moreland exposes the self-defeating nature of scientism and equips us to recognize scientism's harmful presence in different aspects of culture, emboldening our witness to biblical Christianity.

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.

Epistemology is the philosophical study of knowledge. Without knowledge, scientific enquiry is meaningless and we can’t analyse the world around us. But what exactly is knowledge and how do we obtain it? Should we trust our senses? When is belief knowledge? Presuming no prior experience, Robert Martin covers everything in the topic from scepticism and induction to Kant’s transcendentalism. Clear and readable, this audiobook is essential for philosophy students and a much needed introduction for the general reader.

What does it mean to be truthful? What role does truth play in our lives? What do we lose if we reject truthfulness? No philosopher is better suited to answer these questions than Bernard Williams. Writing with his characteristic combinationof passion and elegant simplicity, he explores the value of truth and finds it to be both less and more than we might imagine.

One of the most influential philosophers and theologians in the history of Western thought, St Thomas Aquinas established the foundations for much of modern philosophy of religion, and is famous for his arguments for the existence of God. In this cogent and multifaceted introduction to the great saint's work, Edward Feser argues that you cannot fully understand Aquinas' philosophy without his theology, and vice-versa. He covers Aquinas' thoughts on the soul, natural law, metaphysics, and more.

The Tractatus Logico-Philosophicus (Logical Philosophical Treatise or Treatise on Logic and Philosophy) is the only full-length philosophical book by the Austrian philosopher Ludwig Wittgenstein that was published during his lifetime. The goal of the work is to identify the relationship between language and reality and to define the limits of science. He famously summarized the book in the following way: "What can be said at all can be said clearly; and what we cannot talk about we must pass over in silence."

Geometry defines the world around us, helping us make sense of everything from architecture to military science to fashion. And for over 2,000 years, geometry has been equated with Euclid's Elements, arguably the most influential book in the history of mathematics. In The King of Infinite Space, renowned mathematics writer David Berlinski provides a concise homage to this elusive mathematician and his staggering achievements.

Nobel Laureate Eugene Wigner once wondered about "the unreasonable effectiveness of mathematics" in the formulation of the laws of nature. Is God a Mathematician? investigates why mathematics is as powerful as it is. From ancient times to the present, scientists and philosophers have marveled at how such a seemingly abstract discipline could so perfectly explain the natural world. More than that - mathematics has often made predictions, for example, about subatomic particles or cosmic phenomena that were unknown at the time, but later were proven to be true.

Rand takes listeners step by step through the writing process, providing insightful observations and invaluable techniques along the way. She discusses the psychological aspects of writing and the roles played by the conscious and subconscious mind. She talks about articles and books, explaining how to select a subject and theme, how to identify your audience, and how to write the first draft.

For seven years, Paul Lockhart's A Mathematician's Lament enjoyed a samizdat-style popularity in the mathematics underground, before demand prompted its 2009 publication to even wider applause and debate. An impassioned critique of K-12 mathematics education, it outlined how we shortchange students by introducing them to math the wrong way. Here, Lockhart offers the positive side of the math education story by showing us how math should be done. Measurement offers a permanent solution to math phobia by introducing us to mathematics as an artful way of thinking and living.

Infinite Powers recounts how calculus tantalized and thrilled its inventors, starting with its first glimmers in ancient Greece and bringing us right up to the discovery of gravitational waves. Strogatz reveals how this form of math rose to the challenges of each age: how to determine the area of a circle with only sand and a stick; how to explain why Mars goes "backwards" sometimes; how to turn the tide in the fight against AIDS.

Behind the familiar surfaces of the telephone, radio, and television lies a sophisticated and intriguing body of knowledge known as information theory. This is the theory that has permitted the rapid development of all sorts of communication, from color television to the clear transmission of photographs from the vicinity of Jupiter. Even more revolutionary progress is expected in the future.

In Zero, science journalist Charles Seife follows this innocent-looking number from its birth as an Eastern philosophical concept to its struggle for acceptance in Europe, its rise and transcendence in the West, and its ever-present threat to modern physics.

As Nobel Prize-winning economist Ronald Coase once cynically observed, "If you torture data long enough, it will confess." Lying with statistics is a time-honored con. In Standard Deviations, economics professor Gary Smith walks us through the various tricks and traps that people use to back up their own crackpot theories. Sometimes, the unscrupulous deliberately try to mislead us. Other times, the well-intentioned are blissfully unaware of the mischief they are committing.
