George Stephen Boolos (September 4, 1940 – May 27, 1996) was an American philosopher and a mathematical logician who taught at the Massachusetts Institute of Technology.
Boolos graduated from Princeton University in 1961 with an A.B. in mathematics. Oxford University awarded him the B.Phil in 1963. In 1966, he obtained the first Ph.D. in philosophy ever awarded by the Massachusetts Institute of Technology, under the direction of Hilary Putnam. After teaching three years at Columbia University, he returned to MIT in 1969, where he spent the rest of his career until his death from cancer.
A charismatic speaker well known for his clarity and wit, he once delivered a lecture (1994b) giving an account of Gödel's second incompleteness theorem, employing only words of one syllable. At the end of his viva, Hilary Putnam asked him, "And tell us, Mr. Boolos, what does the analytical hierarchy have to do with the real world?" Without hesitating Boolos replied, "It's part of it".
An expert on puzzles of all kinds, in 1993 Boolos reached the London Regional Final of The Times crossword competition. His score was one of the highest ever recorded by an American. He wrote a paper on "the hardest logic puzzle ever"—one of many puzzles created by Raymond Smullyan.

Willard Van Orman Quine, Professor Emeritus at Harvard University, has been described as the "greatest living English-speaking philosopher". In this series, he takes part in an in-depth personal interview, and a penetrating analysis of his life's work in six panel discussions with some of today's leading philosophers. In discussions with some of today's leading philosophers. In discussions on his most important theses, Quine defends his views against the major criticisms—past and recent—to bring his position right up-to-date.

Now for the The Hardest Logic Puzzle Ever. It was devised American philosopher and logician George Boolos in an article published in The Harvard Review of Philosophy in 1996. Try your hand at Boolos' puzzle, which was also inspired by Raymond Smullyan: Three gods A, B, and C are called, in no particular order, True, False, and Random. True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is a completely random matter. Your task is to determine the identities of A, B, and C by asking three yes-no questions; each question must be put to exactly one god. The gods understand English, but will answer all questions in their own language, in which the words for yes and no are da and ja, in some order. You do not know which word means which. Here's t...

An evil warden holds you prisoner, but offers you a chance to escape. There are 3 doors A, B, and C. Two of the doors lead to freedom and the third door leads to lifetime imprisonment, but you do not which door is what type. You are allowed to point to a door and ask a single yes-no question to the warden. If you point to a door that leads to freedom, the warden does answer your question truthfully. But if you point to the door that leads to imprisonment, the warden answers your question randomly, either saying "yes" or "no" by chance. Can you think of a question and figure out a way to escape for sure?

Can logic be revised? If so, can it be revised rationally? If so, how? Graham Priest addresses these and related philosophical questions in this talk regarding the nature of logic and valid reasoning. This talk was given at the MCMP conference on Paradox and Logical Revision (July 23-25, 2012). I don't own it.
Stephen Neale discusses Bertrand Russell's famous theory of descriptions and some of the philosophical issues surrounding it involving the nature of language and thought. The theory was first introduced in Russell's article "On Denoting" and made significant contributions to the philosophy of language, as well as logic, epistemology, and ontology. Among other things, it made sense out of how we are able to speak and think about things which don't exist. The epistemology which motivated the theory was based on Russell's conception of sense data and his distinction between knowledge by acquaintance and knowledge by description.

This lecture will be concerned with the history and the meaning of natural kinds. The success of science is thought to depend on them. But does the idea of natural kinds imply that conceptual meaning is intrinsic to nature, a view the Objectivist epistemology denies? Glenn Fletcher argues that the current way in which natural kinds are used in science does not conflict with the requirements of the Objectivist theory of concepts. He also discusses recent controversies surrounding this concept, including the status of biological species.

In this program, world-renowned author and professor Bryan Magee and contemporary philosopher Peter Singer discuss rational Hegelian philosophy, and the historicism and organicism at its root. Hegel’s theories of absolute idealism and of a dialectic emphasize history in their development of a model of reality. His concept of this reality as ultimately spiritual, and of philosophy as organic and constantly changing, is examined. The theories of Karl Marx are discussed as essentially Hegelian, but with a practical, economic spin. A BBC Production. Part of the series Great Philosophers.

Do causal notions play any role in physics? Many have thought not. As Bertrand Russell famously once said, causality is a relic of a bygone age. Mathias Frisch discusses this issue at a MCMP conference in Munich.
Friedrich Ludwig Gottlob Frege was a German philosopher, logician, and mathematician. He is considered to be one of the founders of modern logic and made major contributions to the foundations of mathematics. He is generally considered to be the father of analytic philosophy, for his writings on the philosophy of language and mathematics. While he was mainly ignored by the intellectual world when he published his writings, Giuseppe Peano and Bertrand Russell introduced his work to later generations of logicians and philosophers. The Frege programming language is named after him. This video is targeted to blind users. Attribution: Article text available under CC-BY-SA Creative Commons image source in video
See Daniel C Dennett below giving a lecture entitled: 'How did the humanities evolve?' This is the first of four lectures given by Professor Dennett during the Hilary term 2012 as part of the College's broader liberal arts curriculum. He discusses the relevance and importance of scientific understanding in an humanities-based education, and works to encourage a move away from seeing the Arts and Sciences as discontinuous disciplines. How did Homo sapiens evolve to be so different from other animals? How did humans come up with new technological innovations such as speaking, writing and drawing? Daniel C. Dennett addresses these questions amongst many others in this fascinating lecture. Notions of comprehension, acquisition, intelligent design and reasoning are all brought into play he...
