The Egyptian Book of the Dead: A guidebook for the underworld - Tejal Gala

View full lesson: http://ed.ted.com/lessons/the-egyptia...
Ancient Egyptians believed that in order to become immortal after death, a spirit must first pass through the underworld — a realm of vast caverns, lakes of fire, and magical gates. Needless to say, one needed to come prepared. But how? Tejal Gala describes an Egyptian "Book of the Dead" -- a customized magic scroll written by the living to promote a smooth passage to the afterlife when they died.

Americans In Revolt: A Conversation with Sarah Jaffe and Laura Flanders at The New School

source: The New School 2016年9月12日
Sponsored by Nation Books, The Nation Institute and The New School (http://www.newschool.edu), join Nation Institute fellow Sarah Jaffe and journalist Laura Flanders to discuss Jaffe's new title from Nation Books, "Necessary Trouble: Americans in Revolt".
The United States is witnessing a moment of unprecedented political engagement and social activism. Pundits who once fretted about Americans' apathy have, in the last few years, borne witness to uprisings and protests across the country: the growth of the Tea Party, the successful fight for a $15 minimum wage, #BlackLivesMatter, Occupy Wall Street, and the grassroots networks supporting presidential candidates like Bernie Sanders. In Necessary Trouble, Jaffe leads readers into the heart of these movements, explaining what has made ordinary Americans from Seattle to St. Louis to Atlanta become activists.
Necessary Trouble: Americans in Revolt is available in bookstores now.

Transcript - Ebola’s a classic example for me from an evolutionary standpoint of germs and parasites being your real enemy as a big animal, a multicellular organism. Everybody’s terrified of Ebola because you can’t see it and as the saying goes this is not my idea. People aren’t afraid of dying so much as they’re afraid of how they’re going to die. And the Ebola death looks horrible. It’s awful. And what’s making it worse in Africa in particular is scientific illiteracy. People not realizing that these microorganisms get passed from one to another. When I was in South Africa – I guess it’s five years ago a guy told a story – he was from a village, a small village. He was working for the South African Space Agency which they have. And he says it’s going to villages where kids have never seen a magnet and they recommend that you don’t go near that tree because the lightening bird landed on that tree and that means that tree will get struck by lightning and the tree branch will fall on you. And that’s not true by the way. So by having a population of people who don’t really understand germs and how serious they are, the germ gets spread really readily. As far as people freaking out here in the U.S., it’s appropriate. However, the same legislatures when it comes to climate change say well I’m not a scientist. I can’t have an opinion on climate change sure have a lot of opinions about Ebola. There’s a faction of our leaders, elected officials, who continually cuts the budget for the Centers for Disease Control which, to me reflects an ignorance of how serious germs can be.

Metaphysics - Levels of Reality by Kane B

source: Kane B　2016年9月23日
It is natural to think of the world as being divided into a hierarchy of levels: on the lowest level there are fundamental particles such as quarks, electrons, photons, etc; at a higher level, atoms and molecules; at a higher levels, cells; at a higher level, organisms; and so on. This video examine various ways we might try to make the notion of levels precise. I then outline Jaegwon Kim's exclusion argument, which poses a serious problem for the levels picture.

The Infinite Spiral Staircase, Part Two: Semantic Field Theory, with Chris H. Hardy

source: New Thinking Allowed 2015年12月6日
Chris H. Hardy, PhD, is a psychological anthropologist with a specialty in systems theory. She is author of Cosmic DNA at the Origin – A Hyperdimension Before the Big Bang: The Infinite Spiral Staircase Theory, and also The Sacred Network and Networks of Meaning. She also has worked as a parapsychological researcher at the Psychophysical Laboratory in Princeton, New Jersey.
Here she describes how her quest to understand the nature of ultimate reality led her to pursue a career as a researcher and scholar following her explorations as a spiritual sadhu. In endeavoring to explain the phenomena she encountered, she developed “semantic field theory”. Semantic fields are expressions of consciousness, in that they embody meaning. She claims that they exist at every level of reality and are consistent with the philosophy of panpsychism. She maintains that the ritual activity of people, over generations, in temples and spiritual centers tends to embed those locations with powerful semantic fields. These fields also help to explain how telepathy, clairvoyance, and psychokinesis operate.

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 serves as dean of transformational psychology at the University of Philosophical Research. He teaches parapsychology for ministers in training with the Centers for Spiritual Living through the Holmes Institute. He has served as vice-president of the Association for Humanistic Psychology, and is the recipient of its Pathfinder Award for outstanding contributions to the field of human consciousness. 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.

Ludwig Wittgenstein (1889—1951) The Limits of Language

source: pangeaprogressredux 2011年8月20日
http://www.philosophybites.com/
Wittgenstein: "The limits of my language mean the limits of my world"
Ludwig Wittgenstein is one of the most influential philosophers of the twentieth century, and regarded by some as the most important since Immanuel Kant. His early work was influenced by that of Arthur Schopenhauer and, especially, by his teacher Bertrand Russell and by Gottlob Frege, who became something of a friend. This work culminated in the Tractatus Logico-Philosophicus, the only philosophy book that Wittgenstein published during his lifetime. It claimed to solve all the major problems of philosophy and was held in especially high esteem by the anti-metaphysical logical positivists. The Tractatus is based on the idea that philosophical problems arise from misunderstandings of the logic of language, and it tries to show what this logic is. Wittgenstein's later work, principally his Philosophical Investigations, shares this concern with logic and language, but takes a different, less technical, approach to philosophical problems. This book helped to inspire so-called ordinary language philosophy. This style of doing philosophy has fallen somewhat out of favor, but Wittgenstein's work on rule-following and private language is still considered important, and his later philosophy is influential in a growing number of fields outside philosophy.

In 1931 Wittgenstein described his task thus: Language sets everyone the same traps; it is an immense network of easily accessible wrong turnings. And so we watch one man after another walking down the same paths and we know in advance where he will branch off, where walk straight on without noticing the side turning, etc. etc. What I have to do then is erect signposts at all the junctions where there are wrong turnings so as to help people past the danger points.
