1905: The Philosophical Landscape (Ray Monk)
source: Philosophical Overdose 2016年8月23日
Another talk by Ray Monk. The talk concentrates on the work of Bertrand Russell regarding the foundations and philosophy of mathematics which led to the birth of analytic philosophy...
What was happening in Philosophy in 1905? This lecture seeks to answer that question by picking out some of the most influential works of philosophy that were published in or shortly before that year, describing both those works themselves and their intellectual context. The works discussed will include Henri Poincaré's Science and Hypothesis, Edmund Husserl's Logical Investigations, Gottlob Frege's Fundamental Laws of Arithmetic and Bertrand Russell's On Denoting. The hope is to bring out how the seminal works of that period established the tone and content of twentieth century philosophy and drew the battlelines of the great philosophical disputes of the last hundred years: Intuitionism versus Logicism, Phenomenology versus Analytic Philosophy, etc.
This talk is from the 2005 EinsteinFest at the Perimeter Institute (which is perhaps why the talk begins with Einstein).
Philosophy, Mysticism, Spirituality, and Science with Vernon Neppe
source: New Thinking Allowed 2016年5月26日
Vernon Neppe, MD, PhD, FRSSAf, is a neuropsychiatrist and head of the Pacific Neuropsychiatric Institute in Seattle. He is author, with physicist Edward Close, of Reality Begins with Consciousness: A Paradigm Shift that Works. He is also author of Déjà Vu Revisited, Déjà Vu: A Second Look, Déjà Vu: Glossary and Library, Cry the Beloved Mind: A Voyage of Hope, and Innovative Psychopharmacotherapy. His professional publications number over 700. Dr Neppe has amplified many of his concepts in two of the websites linked with his work. On www.Brainvoyage.com, his books are amplified. www.VernonNeppe.org is his gateway and includes more information on the Neppe-Close model of the Triadic Distinction Vortical Paradigm.
Here, Dr. Neppe notes that, while science and mysticism might seem antithetical to each other, this need not be the case. Many ancient philosophers had a deep interest in mysticism. In spite of modern prejudices, this is still the case for many great thinkers in both science and philosophy. Neppe describes his own approach, which involves a “unified monism”. This means, among other things, that the discrete world of finite reality is one with the continuous domain of infinity. The implication of this unity are significant for science and mathematics as well as for spiritual development.
New Thinking Allowed host, Jeffrey Mishlove, PhD, is author of The Roots of Consciousness, Psi Development Systems, and The PK Man. Between 1986 and 2002 he hosted and co-produced the original Thinking Allowed public television series. He is the recipient of the only doctoral diploma in "parapsychology" ever awarded by an accredited university (University of California, Berkeley, 1980). He is also past-president of the non-profit Intuition Network, an organization dedicated to creating a world in which all people are encouraged to cultivate and apply their inner, intuitive abilities.

Transcript - Marsalina: Hi Bill Nye. My name is Marsalina. This is my son Ohenu. And we have a question about your perspective on ghosts and also what do you think happens to your life energy that ceases after you die? Is it just pushing daisies? Thank you.
Bill Nye: Marsha. Greetings. People have wondered about life after death since there have been people. It goes way, way back. We started with ghosts. I’ll tell you I don’t think there’s any such thing. I don’t think there’s anything to be afraid of when it comes to ghosts. I’m a member of both the skeptics and the counsel for scientific inquiry and we have looked and looked for haunted houses, for ghosts in cemeteries, for psychics who believe they’re in touch with people who are dead. And there’s absolutely no credible evidence. There’s no reason to believe that there are ghosts or life after death. People have tried and tried. And you may know that Houdini the famous magician said if anybody can come back from the dead it’s me man. I’m coming. And he never got in touch with anyone. No one ever heard from him. He had a secret word between he and his mother that he said I’ll give you the secret word when I come back. And do you know what the secret word is? Nobody knows, it was secret and he never came back. Read Full Transcript Here: http://goo.gl/vkVOdL.
