Language is an essential part of our lives that we often take for granted. But, if the delicate web of language networks in your brain became disrupted by stroke, illness, or trauma, you could find yourself truly at a loss for words. Susan Wortman-Jutt details a disorder called aphasia, which can impair all aspects of communication.

Reincarnation, Part Four: Implications, with Walter Semkiw

source: New Thinking Allowed    2015年12月25日
Walter Semkiw, MD, is founder and president of the Institute for the Integration of Science, Intuition, and Spirit. He is author of Born Again, Return of the Revolutionaries: The Case for Reincarnation and Soul Groups Reunited, and Origin of the Soul and the Purpose of Reincarnation.
Here Walter Semkiw and host, Jeffrey Mishlove, discuss in further depth the implications of the notion that Mishlove was William James in a past lifetime. Mishlove points out that he remains skeptical of this identification that was made more than fifteen years ago – and that William James also would have been skeptical. He brings up the work in “artificial reincarnation” by the Russian psychiatrist Vladimir Raikov. Semkiw claims that Raikov’s work is best explained in terms of spirit possession or mediumship. Semkiw argues that, over time, evidence of reincarnation is going to create a new world in which people will understand the futility of harboring hostility to others of different ethnic backgrounds.

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.

Professor H. H. Price distinguishes between the causes of belief and the reasons for belief. He then discusses some of the difficulties and complications which arise. H. H. Price was a British philosopher who worked mainly on the philosophy of perception and epistemology.
This talk was given in 1963 as part of the Howison lecture series at the University of California, Berkeley.

Garrett Oliver: "Brooklyn Brewery Brewmaster" | Talks At Google

source: Talks at Google    2016年8月25日
Talks At Google is proud to welcome Garrett Oliver, American brewer and beer author from New York City. Since 1994, he has worked as the brewmaster at the Brooklyn Brewery.
Through the microbrewery panic of the 1990s, into the world-changing craft beer movement of today, Garrett Oliver remains part of the vanguard of American brewing.
He joins us in NYC to discuss American food history from the early 1900s to the present, a journey that takes us from traditional food and drink, through an era of ‘food facsimiles’, and, hopefully, back again.

Is Dropping Out of College Throwing Your Life Away? | Ryan Holiday

source: Big Think    2016年8月13日
Media strategist, writer, and college drop-out Ryan Holiday questions whether college is just an expensive way to go through the motions. Holiday's latest book is "Ego Is The Enemy" (http://goo.gl/T5lxKz).

Transcript - For me going to college was just an assumption that was made and there was no challenging whether – if you're smart and you do well in school you go to college because that's how you're successful life. And I think that's true for a lot of people. And I really liked collage. The decision to drop out was not one that I took lightly and I don't think it's necessarily – I didn't drop out and then figure out what I wanted to do with my life, I had a job offer to be a research assistant to work at a talent agency in Hollywood. I had these offers and I did the math and I said hey if these were my offers the day after graduation I would have considered college a success. So that's why I personally dropped out. And a few years ago I wrote an article about dropping out of college and sort of what that experience was like and how it shaped my life. And the funny or scary thing is that it now ranks really well on Google if you search the phrase dropping out of college. And so I get a lot of emails almost every day at like 2:00 or 3:00 in the morning some kid who's not happy with college comes back to his dorm room, they Google that phrase and then they email me. And a lot of times they want me to tell them that it's okay to drop out of college. And I usually don't, one, because it was such a terrifying decision to make and it was so unpleasant. I mean my parents didn't take it well and it was so hard that I'm not glib about recommending it to other people. But also I think Mark Zuckerberg, again, didn't drop out of college to create Facebook, he created Facebook in college and then he moved to California for the summer and it was doing so well that he decided not to go back. I think Bill Gates' story is similar. Most of the really successful college dropouts used the platform that is going to a university, it's using the status of being a student. They started something and it got going quickly enough that it didn't make sense to continue going to school. Read The Full Transcript Here: http://goo.gl/3sgsVw.
