Foucault's Power is the antidote to pretentious philosophical obscurity you've been waiting for. This irreverent guide takes you on a sarcasm-soaked journey through Michel Foucault's most influential ideas—from his analysis of prisons and power to his baffling observations about sexuality and truth—all while mercilessly mocking the cult of incomprehensibility that has grown around him.

Sophistry: The Dark Art Undermining Truth is a groundbreaking exploration into one of humanity’s oldest and most dangerous deceptions. This book reveals the insidious techniques of sophistry, exposing how it manipulates thought, divides societies, and erodes trust in an age of unprecedented complexity. Ethan Solace, an interdisciplinary psychologist and thought leader, takes listeners on a powerful journey through the shadows of manipulation, examining how sophistry infiltrates education, media, technology, and public discourse.

With The Interpretation of Cultures, the distinguished anthropologist Clifford Geertz developed the concept of thick description, and in so doing, he virtually rewrote the rules of his field. Culture, Geertz argues, does not drive human behavior. Rather, it is a web of symbols that can help us better understand what that behavior means. A thick description explains not only the behavior, but the context in which it occurs, and to describe something thickly, Geertz argues, is the fundamental role of the anthropologist.

We feel love. We spread love. We hide it away. We find love, fall in it, and get stuck in it. Love hurts, it stinks and it heals. There are lovebugs, love birds and puppy love. There are labors of love and tough love. We have love-hate relationships. We find one to love and sometimes create love triangles. We can make love and make a love child. Kids love sugar, and love can be pretty sweet. Love is the answer. Love is all we need. It’s so fine, it’s sunshine. Love is the light. Love is the way.

Logic is often perceived as having little to do with the rest of philosophy, and even less to do with real life. In this lively and accessible introduction, Graham Priest shows how wrong this conception is. He explores the philosophical roots of the subject, explaining how modern formal logic deals with issues ranging from the existence of God and the reality of time to paradoxes of probability and decision theory. Along the way, the basics of formal logic are explained in simple, non-technical terms, showing that logic is a powerful and exciting part of modern philosophy.

This timely audio edition of A Rulebook for Arguments sharpens an already-classic text, adding updated examples and a new chapter on public debates that provides rules for the etiquette and ethics of sound public dialogue as well as clear and sound thinking in general.

With his characteristic clarity and elegance A. C. Grayling takes the listener from the worldviews and moralities before the age of the Buddha, Confucius and Socrates, through Christianity's dominance of the European mind, to the Renaissance and Enlightenment, and on to Mill, Nietzsche, Sartre and philosophy today. And, since the story of philosophy is incomplete without mention of the great philosophical traditions of India, China and the Persian-Arabic world, he gives a comparative survey of them, too.

Noam Chomsky is widely known and deeply admired for being the founder of modern linguistics, one of the founders of the field of cognitive science, and perhaps the most avidly read political theorist and commentator of our time. In these lectures, he presents a lifetime of philosophical reflection on all three of these areas of research to which he has contributed for over half a century.

Philosophical Investigations was published in 1953, two years after the death of its author. In the preface written in Cambridge in 1945 where he was professor of philosophy he states: ‘Four years ago I had occasion to re-read my first book (the Tractatus Logico-Philosophicus) and to explain its ideas to someone. It suddenly seemed to me that I should publish those old thoughts and the new ones together: that the latter could be seen in the right light only by contrast with and against the background of my old way of thinking.’

Thomas Gilovich offers a guide to the fallacy of the obvious in everyday life. Illustrating his points with examples, and supporting them with the latest research findings, he documents the cognitive, social, and motivational processes that distort our thoughts, beliefs, judgments and decisions.

Your argument is valid and you know it; yet once again you find yourself leaving a debate feeling defeated and embarrassed. The matter is only made worse when you realize that your defeat came at the hands of someone's abuse of logic - and that with the right skills you could have won the argument. The ability to recognize logical fallacies when they occur is an essential life skill. Mastering Logical Fallacies is the clearest, boldest, and most systematic guide to dominating the rules and tactics of successful arguments.

Each year,John Brockman, publisher of Edge.org, challenges some of the world's greatest scientists, artists, and philosophers to answer a provocative question crucial to our time. In 2014 he asked 175 brilliant minds to ponder: What scientific idea needs to be put aside in order to make room for new ideas to advance? The answers are as surprising as they are illuminating.

Upon its first English publication in 1959, Popper's The Logic of Scientific Discovery revolutionized thinking about the scientific method. Largely an exploration of the demarcation problem, or what distinguishes science from non-science, Popper introduced and defended his concept of falsifability -- that scientific systems are ones open to empirical disconfirmation -- against the prevailing views of his day.

Irony and sarcasm are two of the most misused, misapplied, and misunderstood words in our conversational lexicon. In this volume in the MIT Press Essential Knowledge series, psycholinguist Roger Kreuz offers an enlightening and concise overview of the life and times of these two terms, mapping their evolution from Greek philosophy and Roman rhetoric to modern literary criticism to emojis.

By explaining how the human brain works and outing its most irrational processes, this book provides the thinking tools that will help you make better decisions, ask the right questions (at the right time), know what to look for when evaluating information, and understand how your own brain subconsciously clouds your judgment. Think you're too smart to be easily misled? Harrison summarizes scientific research showing how easily even intelligent and well-educated people can be fooled.
