This book explores how meaning, often assumed to be a stable or innate feature of reality, is in fact a constructed phenomenon — shaped, transmitted, and manipulated through language, cultural systems, economic structures, and ideology. Drawing on thinkers such as Wittgenstein, Lacan, Orwell, and contemporary cultural critics, the text unpacks how language limits thought, how culture recycles and fossilizes symbolic forms, and how capitalism turns meaning into a consumable commodity.

In How Propaganda Works, Jason Stanley demonstrates that more attention needs to be paid. He examines how propaganda operates subtly, how it undermines democracy - particularly the ideals of democratic deliberation and equality - and how it has damaged democracies of the past.

Solve for Happy is a startlingly original book about creating and maintaining happiness, written by a top Google executive with an engineer's training and fondness for thoroughly analyzing a problem. In 2004 Mo Gawdat, a remarkable thinker whose gifts had landed him top positions in half a dozen companies and who - in his spare time - had created significant wealth, realized that he was desperately unhappy. A lifelong learner, he attacked the problem as an engineer would, examining all the provable facts and scrupulously following logic.

"Philosophy is not a theory," asserted Austro-British philosopher Ludwig Wittgenstein (1889-1951), "but an activity." In this 1921 opus, his only philosophical work published during his lifetime, Wittgenstein defined the object of philosophy as the logical clarification of thoughts and proposed the solution to most philosophic problems by means of a critical method of linguistic analysis.

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.

The Problems of Philosophy is a 1912 book by Bertrand Russell, in which the author attempts to create a brief and accessible guide to the problems of philosophy. Focusing on problems he believes will provoke positive and constructive discussion, Russell concentrates on knowledge rather than metaphysics: If it is uncertain that external objects exist, how can we then have knowledge of them but by probability.

Analogy is the core of all thinking. This is the simple but unorthodox premise that Pulitzer Prize-winning author Douglas Hofstadter and French psychologist Emmanuel Sander defend in their new work. Hofstadter has been grappling with the mysteries of human thought for over 30 years. Now, with his trademark wit and special talent for making complex ideas vivid, he has partnered with Sander to put forth a highly novel perspective on cognition.

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.

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.

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.

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.
