"The Categories" by Aristotle is a philosophical text from ancient Greece that enumerates all possible kinds of things that can be the subject or predicate of a proposition.

Many insiders in the tech plex are deeply concerned about AI's trajectory—rightly seeing it as existential risk. Dr. Marc Gafni identifies two forms: the potential death of humanity through extinction events, and the potential death of our humanity. We become irrelevant to governance and economics, unneeded as workers, controlled by systems that shape our desires, stripped of genuine choice—heading toward a totalitarian global digital dictatorship. In this monograph, Dr. Marc Gafni offers a multilayered diagnosis of our AI moment—one that far exceeds technological concerns.

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.

The now-classic Metaphors We Live By changed our understanding of metaphor and its role in language and the mind. Metaphor, authors George Lakoff and Mark Johnson explain, is a fundamental mechanism of mind, one that allows us to use what we know about our physical and social experience to provide understanding of countless other subjects. Because such metaphors structure our most basic understandings of our experience, they are "metaphors we live by"—metaphors that can shape our perceptions and actions without our ever noticing them.

"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.

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.

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.

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.

The front cover of the second edition of Language, Truth and Logic carried this statement in capital letters: ‘THE CLASSIC TEXT WHICH FOUNDED LOGICAL POSITIVISM - AND MODERN BRITISH PHILOSOPHY.’ It was a bold statement, but the book, first published in 1936 when A. J. Ayer was just 25 and a lecturer on philosophy at Christ Church, Oxford, drew unstinting praise from leading figures in the field, including Bertrand Russell.

This audiobook proposes a radical yet disciplined thesis: the Gospel is not only interpretable, but formally expressible, and its internal structure requires formalization if it is to remain stable, transmissible, and intelligible across radically different forms of intelligence.

A book about why humans think irrationally — and why logic fails in the real world. We live in an age of information and still make emotional, biased, and mathematically insane decisions. Why? Because the human brain is wired for story over statistics, tribe over truth, and certainty over reality. In When Logic Betrays You, Kevin L. Whitworth blends cognitive psychology, behavioral science, and dark humor to expose how cognitive biases sabotage critical thinking.

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.’

This classic work of political theory and practice offers an account of the modern Machiavellians, a remarkable group who have been influential in Europe and practically unknown in the United States. The book devotes a long section to Machiavelli himself as well as to such modern Machiavellians as Gaetano Mosca, Georges Sorel, Robert Michels and Vilfredo Pareto. Burnham contends that the writings of these men hold the key both to the truth about politics and to the preservation of political liberty.
