Philosophy Logic

One of the two major philosophical traditions of the twentieth century was linguistic analysis, derived largely from Wittgenstein. The other, diametrically opposed, came from Heidegger, and its fundamental question was, "What is the meaning of existence?" For Heidegger, this question could not simply be "analyzed away". It was beyond the reach of logic or reason. It was the primary "given" of every individual life. To confront it, Heidegger needed to develop an entire new form of philosophy.

Quantum physics is notable for its brazen defiance of common sense. (Think of Schrödinger's Cat, famously both dead and alive.) An especially rigorous form of quantum contradiction occurs in experiments with entangled particles. Our common assumption is that objects have properties whether or not anyone is observing them, and the measurement of one can't affect the other. Quantum entanglement rejects this assumption, offering impeccable reasoning and irrefutable evidence of the opposite. Is quantum entanglement mystical, or just mystifying?

Confucius knew all about life and told us how to behave, but we can't find out precisely what he was up to. His well-meaning platitudes, quaint maxims, and quasi-enigmatic anecdotes combined to produce an ideal philosophy for civil servants. It would appear that his aim was to turn his pupils into good government officials, but his teachings succeeded beyond his wildest expectations, providing rules of conduct and spiritual fodder for more than two thousand years.

Why do Internet, financial service, and beer commercials dominate Super Bowl advertising? How do political ceremonies establish authority? Why does repetition characterize anthems and ritual speech? Why were circular forms favored for public festivals during the French Revolution? This book answers these questions using a single concept: common knowledge.

In St. Augustine in 90 Minutes, Paul Strathern offers a concise, expert account of St. Augustine's life and ideas and explains their influence on man's struggle to understand his existence in the world. The book also includes selections from St. Augustine's work, a brief list of suggested readings for those who wish to delve deeper, and chronologies that place St. Augustine within his own age and in the broader scheme of philosophy.

Kierkegaard wasn't really a philosopher in the academic sense. Yet he produced what many people expect of philosophy. His subject was the individual and his or her existence, the "existing being." In Kierkegaard's view, this purely subjective entity lay beyond the reach of reason, logic, philosophical systems, theology, or even "the pretenses of psychology." Nonetheless, it was the source of all these subjects. The branch of philosophy to which Kierkegaard gave birth has come to be known as existentialism.

This work sets forth a theory which is speculative in nature, there being no verifying experiments. It is based on the idea of the reversibility of everything in time; that is, that every type of process has its time image, a corresponding process which is its exact reverse with respect to time.

Le "Discours de la méthode" est un texte composite, assez peu méthodique en vérité, qui touche à la morale, à la logique, aux sciences. La méthode proprement dite se résume en peu de règles : "ne recevoir jamais aucune chose pour vraie, que je ne la connusse évidemment être telle" ; "diviser chacune des difficultés que j'examinerais" ; "conduire par ordre mes pensées" et m'assurer, par des "dénombrements si entiers, et des revues si générales", de n'avoir rien omis dans ces "chaînes de raisons", sur le modèle des géomètres.

Think Like Socrates doesn’t go into boring details and endless philosophical methodology. It provides you instead with lessons from one of the best philosophers in human history, Socrates, and keeps you hooked as you explore the fascinating techniques of the thinking genius. Socrates is often mentioned as the founder of Western philosophy. He encouraged his students to think for themselves instead of having someone provide the solution. He was an excellent communicator and questioner. He is a human worth examining.

Aristotle wrote on everything from the shape of seashells to sterility, from speculations on the nature of the soul to meteorology, poetry, art, and even the interpretation of dreams. Apart from mathematics, he transformed every field of knowledge that he touched. Above all, Aristotle is credited with the founding of logic. When he first divided human knowledge into separate categories, he enabled our understanding of the world to develop in a systematic fashion.

Even the most reasonable of us can be selective about when we think reasonably—we might take pride in our rationality about professional matters but follow our gut when it comes to social issues, for example. In a world of rabbit holes, echo chambers, and disinformation, how can we keep our heads on straight more consistently? How to Think More and Better offers a philosopher's advice on becoming a more rational and critical thinker.

In closely reported stories from the streets of New York to the seats of intellectual power, MacDonald shows how bad ideas get started and then acquire a life of their own. Her reports trace the transformation of influential opinion-makers and large philanthropic foundations from confident advocates of individual responsibility, opportunity, and learning into apologists for the welfare state.

David Hume reduced philosophy to ruins: he denied the existence of everything, except our actual perceptions themselves. I alone exist, he argued, and the world is nothing more than part of my consciousness. Yet we know that the world remains, and we go on as before. What Hume expressed was the status of our knowledge about the world, a world in which neither religion nor science is certain.

In a letter of 1932, Karl Popper described Die beiden Grundprobleme der Erkenntnistheorie–The Two Fundamental Problems of the Theory of Knowledge–as ‘…a child of crises, above all of …the crisis of physics.' The two fundamental problems of knowledge that lie at the center of the book are the problem of induction, that although we are able to observe only a limited number of particular events, science nevertheless advances unrestricted universal statements; and the problem of demarcation, which asks for a separating line between empirical science and non-science.

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.
