The PK Man and Mercurial Hermeneutics with Jason Reza Jorjani

source: New Thinking Allowed    2016年9月25日
Jason Reza Jorjani is a philosopher and faculty member at the New Jersey Institute of Technology. He is author of Prometheus and Atlas.
Here he describes how he placed Jeffrey Mishlove’s study of Ted Owens, “the PK Man”, into a larger cultural and philosophical context. He defines Mercurial Hermeneutics as the art of interpreting the manifestations of the trickster archetype in the world. He suggests that this archetype, aka Hermes or Mercury, is the intelligence behind the psychokinetic demonstrations of Ted Owens and others (such as Uri Geller). He also maintains that the very same intelligence was behind the establishment of the Abrahamic religious traditions.

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 a past vice-president of the Association for Humanistic Psychology; and is the recipient of the Pathfinder Award from that Association for his contributions to the field of human consciousness exploration. 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.

Few individuals have influenced the world and many of today’s thinkers like Plato. He created the first Western university and was teacher to Ancient Greece’s greatest minds, including Aristotle. But even he wasn’t perfect. Along with his great ideas, Plato had a few that haven’t exactly stood the test of time. Wisecrack gives a brief rundown of a few of Plato’s best and worst ideas.

The Psychology (and Politics) of Disgust | Kathleen McAuliffe

source: Big Think   2016年9月23日
How easily grossed out are you? Your sensitivity to disgust reveals more about you than you'd probably be comfortable with, from how you'll vote in this election to your potential to be a cold-blooded killer. Kathleen McAuliffe's book is This Is Your Brain on Parasites: How Tiny Creatures Manipulate Our Behavior and Shape Society goo.gl/qgOI62
Read more at BigThink.com: http://bigthink.com/videos/kathleen-m...

Similar parts of the brain - there's a lot of overlap in how we process both visceral disgust and moral disgust. Psychopaths - needless to say they're these cold-blooded killers are over representative in many of our high security jails. And these individuals show damage to many of the same circuits that are involved in disgust. Another group of individuals, although they're not predatory but people with Huntington's disease it also damages some of the circuits that are involved in disgust. People with Huntington's disease tend not to be empathetic and they think that this is related to these circuits being damaged. And they're almost unique in that they experience almost no visceral disgust whatsoever. So somebody with Huntington's disease, for example, would think nothing of picking up feces with their bare hands. So there is this sort of very interesting interrelationship, at least in the brain, between visceral and moral disgust.
A little known fact is that conservatives are more disgust sensitive. There's a huge variation acrostic populations in how disgust sensitive people are. There's actually standardized scales that measure, for example, the questionnaire you fill out and it will ask you questions about like how revolted you would be If you stepped on dog poop or if you saw a cockroach on pizza or a dirty toilet. And as a result of filling out these questionnaires they've been able to look to see if there's parallels between how disgust sensitive someone is and how conservative they are. And indeed there is a correlation. And probably the reason for that is because, again, the conservatives if you kind of really breakdown their belief systems they tend to have conservative sexual values. So, for example, concepts like virginity pledges are ideas that they're fond of. They also tend to be more opposed to immigration and foreigners are a leading source, at least in centuries past, foreigners were a leading source of exotic germs for which we had no natural defenses. So it's speculated that that could be another factor behind why people who are more conservative in their political ideology why they tend to be opposed to immigration.
Conservatives also tend to be very tradition bound. They tend to be a little bit more rigid about following religious doctrine. And again, a lot of religious practices may help to protect against infection. So that's the leading theory as to why you see this association. But in general, even in large survey studies they've shown this link between germophobia and xenophobia. So, for example, there was a paper actually that's about to be published and I think they looked at 2000 Danes and 1200 Americans, representative samples from both countries. And they found that opposition to immigration increased in direct proportion to the disgust sensitivity of the individual.
Another group did a study of 25,000 Americans. The study was done at the time of the 2008 presidential election between John McCain, a more conservative candidate, of course, and Barack Obama. And they found that the more disgust sensitive the person the more likely they would vote for John McCain. And they actually showed the proportion of votes that went to McCain in each state. It was based on the average disgust sensitivity of the state based on individual respondents to the survey.

Think Again Podcast - Ian McEwan - A King of Infinite Space

source: Big Think    2016年9月25日
This week's guest is novelist Ian McEwan. He’s the bestselling author of 16 books, including Atonement, which won the National Book Critics Circle Award and the WH Smith Literary award and Amsterdam, which won the Booker Prize. His latest book, Nutshell, is a darkly funny, brilliant riff on Shakespeare’s Hamlet, told from the point of view of an extremely articulate, nine month old fetus, viewing an unfolding murder plot from the limited vantage point of his mother’s womb.
In this far-ranging, lively dialogue, McEwan and host Jason Gots discuss Hamlet, moral quandaries, and how to set boundaries in a world that threatens to pull you in every direction.
Each week on Think Again, we surprise smart people you may have heard of with short clips from Big Think's interview archives on every imaginable subject. These conversations could, and do, go anywhere.

Eating Disorders, Mental Health and Body Image: The Public Health Connec...

source: Harvard University    2016年9月22日
More than 30 million Americans — women and men, children and adults — grapple with eating disorders. These complex illnesses, which include anorexia, bulimia, and binge eating disorder, severely undermine health and cost lives. This event explored the many dimensions to eating disorders, including their biological bases, risk factors and treatment options. What role does body image play, and how do industries, such as fashion and advertising, often promulgate unrealistic societal standards of beauty? How might women and girls, in particular, be affected by such pressure? And what’s to be done? For example, would enacting legislation that requires minimum BMIs for models, or requiring disclosures of digitally altered ads, help? This panel included expertise in psychiatry, children’s health, policy and eating disorders prevention.
Part of The Dr. Lawrence H. and Roberta Cohn Forums, this event was presented September 20, 2016 in Collaboration with PRI’s The World and WGBH.

What Does Evolution Mean For Morality? Peter Singer On Evolution & Ethics

source: Philosophical Overdose    2014年6月22日
Can evolution help us to understand ethics & values? After arguing against some of the misunderstandings regarding evolution (e.g. that it implies egoism/selfishness or that "might is right"), Peter Singer argues that evolution is neutral with regard to values (the naturalistic fallacy), but that understanding evolution does help us to understand human nature; and since the field of ethics is often interested in changing behavior, evolution gives us valuable clues as to what is, or is not, likely to work. Singer also considers the argument that since our moral sense has evolved, it serves to enhance our reproductive fitness, and hence is not a guide to what is really right or wrong. He argues that there is some truth to this claim, but properly understood, it should lead us to skepticism about some ethical views, but not about ethics itself.
This talk was given at the University of Sydney in 2011. I don't own the content.
