How do you get what you want, using just your words? Aristotle set out to answer exactly that question over two thousand years ago with a treatise on rhetoric. Camille A. Langston describes the fundamentals of deliberative rhetoric and shares some tips for appealing to an audience’s ethos, logos, and pathos in your next speech.

The Science of Fear-Mongering: How to Protect Your Mind from Demagogues ...

source: Big Think     2016年8月18日
Harvard psychologist Susan David explains the dangers of fear-mongering, the questionable ethics of journalism in spreading hate politics, and the disturbing way that repetition wears down our brain's resistance to fallacies and hate speech. David's book is "Emotional Agility: Get Unstuck, Embrace Change, and Thrive in Work and Life " (http://goo.gl/LQ6VWQ).

Transcript - How do we thrive in a world where every which way we turn our fear is being activated by politicians, by the media and by the desperate events that are happening around us? What is really fascinating when we look at the brain research around fear is that our brains proxy anything that feels unfamiliar, incoherent or inaccessible as being unsafe. There is fascinating research that shows that when people have lower levels of self-esteem and they are in a job in which they are recognized and promoted, that promotion can feel incoherent to the person with low self-esteem. They have low self-esteem and they might be used to and expecting to be treated badly. So what is fascinating is the results showing that when people are promoted when they have a lower levels of self-esteem they are more likely to leave their jobs. Fear is an incredibly, incredibly powerful force in our lives and our brains are fairly immature in assessing anything that feels slightly incoherent for unfamiliar as unsafe.
What this might mean is that if you are used to hearing a story time and time again from a parent or from a partner about how you are not good enough, you are more likely to be drawn to that relationship because it feels familiar. The messaging that you are getting time and time again is connected with what you expect to get. Read Full Transcript Here: http://goo.gl/9nGGSq.

Reflections on The PK Man with Debra Lynne Katz

source: New Thinking Allowed     2016年5月12日
Debra Lynne Katz, MSW, is both a talented remote viewer and a psychic reader. She is author of You Are Psychic: The Art of Psychic Reading & Healing, Extraordinary Psychic: Proven Techniques to Master Your Natural Psychic Abilities, and Freeing the Genie Within: Manifesting Abundance, Creativity, and Success in Life. She is a parapsychology researcher, having twice received the annual Warcollier Prize from the International Remote Viewing Association for an outstanding research proposal. She is the director of the International School of Clairvoyance.
Here she turns the tables on New Thinking Allowed host, Jeffrey Mishlove, and interviews him about his book, The PK Man. In so doing, she expresses her own interest in this case and in learning how to cultivate her own PK abilities. She focuses particularly onTed Owens’ own story, as he described it himself to Jeffrey. She also raises questions concerning the safety and ethics of cultivating Psychokinesis.

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). His master's degree is in criminology. 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.
