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.’

Inside this brilliant three-in-one book collection, you’ll uncover a wealth of philosophical insights about truth, faith, and the universe around us. Drawing on the arguments and musings of the famed philosopher, David Hume, this book reveals his ideas on the questions that define our very existence. Brought to life in this collection for a modern audience David Hume’s work has stood the test of time to resonate with people across the ages.

Whenever we worry about what to eat, how to love, or simply how to be happy, we are worrying about how to lead a good life. No goal is more elusive. In How to Be a Stoic, philosopher Massimo Pigliucci offers Stoicism, the ancient philosophy that inspired the great emperor Marcus Aurelius, as the best way to attain it. Stoicism is a pragmatic philosophy that teaches us to act depending on what is within our control and separate things worth getting upset about from those that are not.

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.

Le bon sens est la chose au monde la mieux partagée, car chacun pense en être si bien pourvu que ceux même qui sont les plus difficiles à contenter en toute chose, n'ont point coutume d'en désirer plus qu'ils en ont.

Daniel Everett, then a Christian missionary, arrived among the Pirahã in 1977 - with his wife and three young children - intending to convert them. What he found was a language that defies all existing linguistic theories and reflects a way of life that evades contemporary understanding. The Pirahã have no counting system and no fixed terms for color. They have no concept of war or of personal property.

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.

What is language? Why do we have it? Where does it come from? Why does that matter? Upending centuries of scholarship (including, most recently, Chomsky and Pinker) The Language Game shows how people learn to talk not by acquiring fixed meanings and rules, but by picking up, reusing and recombining countless linguistic fragments in novel ways.

Par une analyse logique minutieuse, Orobio expose les contradictions dans la philosophie matérialiste de Jan Bredenburg, affirmant que Spinoza et ses contemporains promeuvent un nouvel athéisme panthéiste, remplaçant Dieu par la "Nature" et ignorant les fondements de la logique, de la grammaire, de la métaphysique et de l'ontologie.

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.

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.

"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.

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.

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.

Despite 21st-century fears of an "epidemic" of loneliness, its history has been sorely neglected. A Biography of Loneliness offers a radically new interpretation of loneliness as an emotional language and experience. Using letters and diaries, philosophical tracts, political discussions, and medical literature from the 18th century to the present, historian of the emotions Fay Bound Alberti argues that loneliness is not a historical, universal phenomenon. It is, in fact, a modern emotion: before 1800, its language did not exist.
