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.’

In this book, we have included excerpts from the Socratic dialogues (as penned by his most famous student, Plato) and Professor Andrea Diem-Lane's brilliant treatise on the "Cerebral Mirage" which brings Plato and Socrates up to date by showing how the latest findings in quantum theory and neuroscience substantiate much of early Greek skepticism, particularly concerning how easily we can be deceived by our various forms of certainty.

The Tractatus Logico-Philosophicus (Logical Philosophical Treatise or Treatise on Logic and Philosophy) is the only full-length philosophical book by the Austrian philosopher Ludwig Wittgenstein that was published during his lifetime. The goal of the work is to identify the relationship between language and reality and to define the limits of science. He famously summarized the book in the following way: "What can be said at all can be said clearly; and what we cannot talk about we must pass over in silence." 

According to Littlewood's Law of Miracles (based on the theory of large numbers and probability), you should expect something truly unusual to happen every 35 days - so strange, in fact, that it will look like a miracle. This book explains how the improbable is probable by focusing on desultory decussation (where two random events from an interesting intersection - a synchronicity) and Littlewood's work in number theory at Cambridge University in the last century. Also explains such concepts as apohenia and patternicity.

L. Williams, in translating Giordano Bruno's Gli Eroici Furori (Heroic Enthusiasts) from the original Italian into English back in 1887 and 1889, has done a great service to humanity. His introduction is especially illuminating as it contextualizes Bruno's life until his tragic death at the age of 52 and provides us with a tantalizing glimpse into his cosmological philosophy. It is my hope that this small book, which is drawn exclusively from Williams' work, will serve as an intellectual appetizer and lead to a deeper plunge into Bruno's fascinating thought.

This book provides a wide overview of Darwin's views on a variety of subjects. It also draws out some of the implications of his groundbreaking work on psychology and philosophy.

Ludwig Wittgenstein (1889-1951) was an extraordinarily original thinker, whose influence on 20th-century thinking far outside the bounds of philosophy alone. In this engaging Introduction, A. C. Grayling makes Wittgenstein's thought accessible to the general listener by explaining the nature and impact of Wittgenstein's views. He describes both his early and later philosophy, the differences and connections between them, and gives a fresh assessment of Wittgenstein's continuing influence on contemporary thought. 

The Red Book, published to wide acclaim in 2009, contains the nucleus of C. G. Jung's later works. It was here that he developed his principal theories of the archetypes, the collective unconscious, and the process of individuation that would transform psychotherapy from treatment of the sick into a means for the higher development of the personality.

In the Fall of 1991 students enrolled in Introduction to Philosophy classes at Mount San Antonio College conducted interviews with some of the most prominent philosophers in California. Ten questions were asked of each philosopher, including queries about the existence of God, life after death, and the interface between human and artificial intelligence. The interviews ranged from personal one on one conversations, to telephone interviews, to mailed written responses.

A major new collection from "arguably the most important intellectual alive" ( The New York Times). Noam Chomsky is universally accepted as one of the preeminent public intellectuals of the modern era. Over the past thirty years, broadly diverse audiences have gathered to attend his sold-out lectures. Now, in Understanding Power, Peter Mitchell and John Schoeffel have assembled the best of Chomsky's recent talks on the past, present, and future of the politics of power.

One of the most significant discoveries of modern science is that the world we perceive around us is not as it appears. Rather, neuroscience, evolutionary biology, and quantum physics have demonstrated that our day-to-day reality is a relative construct, built upon a scaffolding of information bits that betray their real origin and causation.  

Continuing where Thus Spoke Zarathustra left off, Nietzsche's controversial work Beyond Good and Evil is one of the most influential philosophical texts of the 19th century and one of the most controversial works of ideology ever written. Attacking the notion of morality as nothing more than institutionalised weakness, Nietzsche criticises past philosophers for their unquestioning acceptance of moral precepts. Nietzsche tried to formulate what he called "the philosophy of the future".

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.

The Problems of Philosophy discusses Bertrand Russell's views on philosophy and the problems that arise in the field. Russell's views focus on knowledge rather than the metaphysical realm of philosophy. The Problems with Philosophy revolves around the central question that Russell asks in his opening line of Chapter 1 - Is there any knowledge in the world which is so certain that no reasonable man could doubt it?

Have you heard that language is violence and that science is sexist? Have you read that certain people shouldn't practice yoga? Or been told that being obese is healthy, that there is no such thing as biological sex, or that only White people can be racist? Are you confused by these ideas, and do you wonder how they have managed to challenge the logic of Western society? In this probing volume, Helen Pluckrose and James Lindsay document the evolution of the dogma that informs these ideas, from its coarse origins in French postmodernism to its refinement within activist academic fields.
