source: Closer To Truth 2016年9月29日
Dark matter, though it cannot be seen, may account for roughly one quarter of all the mass-energy of the universe. If it were not for the gravity of dark matter, galaxies could not hold together such that stars and planets would go flying off independently. But what is dark matter?

How Precognition Works with Edwin C. May

source: New Thinking Allowed 2016年9月18日
Edwin C. May, PhD, was involved in the military intelligence psychic spying program, popularly referred to as Stargate, for over twenty years. During the last decade, he was the director of research for that program. In this context, he produced over a hundred scientific publications. His academic training was in experimental nuclear physics. He is coauthor of ESP Wars: East and West and also Anomalous Cognition: Remote Viewing Research and Theory. He is the coeditor of a two volume anthology titled Extrasensory Perception: Support, Skepticism, and Science.
Here he shares the progress he has made in developing a model of precognition based on our understanding of physics, neurophysiology, and psychology. He postulates a channel of information from either actual or possible futures to the present. This is a physics problem that could be addressed in the context of retro-causality. He also postulates that individuals who have a high degree of synesthesia are best able to integrate psi information into their normal processing of perceptual information, due to neural hyperconnectivity.

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.

Chinese Language and Civilization by Wesley Cecil

source: Wes Cecil 2013年1月13日
A lecture by Wesley Cecil PhD delivered at Peninsula College. I explore the incredible history of Chinese civilization and language and the current cultural challenges in China.
Two Notes: I referred to the age of Old Testament texts early in the lecture - I meant New Testament texts. The earliest NT texts date from around 200 AD most are later.
The Tale of the Marshes or Water Margins was set in the Song Dynasty.
This is what happens when you have so many dates and names and you lecture without notes.

How Parasites Commandeer and Change Our Neurocircuits | Kathleen McAuliffe

source: Big Think 2016年9月19日
Parasites are more than dormant feeders. Microscopic science is uncovering the ways viruses and bacteria prey on their hosts, influencing them to behave in some very strange ways. Kathleen McAuliffe's book is This Is Your Brain on Parasites: How Tiny Creatures Manipulate Our Behavior and Shape Society: goo.gl/ABWKvg
Read more at BigThink.com: http://bigthink.com/videos/kathleen-m...

Kathleen McAuliffe: We know that parasites can make us sick, of course, and siphon off our nutrients, but it's very surprising to hear that some of them, in fact there may be a large number, at least a hundred are known about at this point in time manipulate the behavior of their host in order to enhance their own transmission. And the best way to understand this phenomenon I think is with an example. And one is a cat parasite called Toxoplasma Gondii or just Toxoplasma for short. I first learned about this parasitic manipulation while just reading about scientific research and I came across a study that showed that rodents that are infected with this parasite, they can pick up the parasite from the ground. Cats defecate this parasite so rodents as they are scavenging around can pick up the parasite and it then invades their brain and it actually tinkers with the animal's neural circuits in such a fashion that it makes it attracted to the scent of cat urine.
And when I say attracted I mean sexually attracted. The rodents become sexually aroused by the scent of cat urine so they approach and needless to say they're not long for this world they soon end up in the belly of a cat and that's the only place where this parasite can sexually replicate. So that's its little trick. And it does many other things as well. For example, the same parasite goes to the testicles and jacks up production of the sex hormone testosterone. In females, by means nobody's figured out yet, it can increase the level of the sex hormone progesterone. And in both cases these changes make the rodent more embolden and cause the rodent to sort of lower its guard and to act in foolish ways around cats. So that's yet another example of other tricks it has for getting back into the belly of a cat.

This parasite can also infect us. One of the ways we can get it is changing a cat's litter box. And the current thinking in medicine is that the parasite it mainly poses a threat to a developing fetus and can harm the developing baby's nervous system or even cause blindness. And it's also well known to be a threat to people who are immuno-compromised, so for example, people who have received transplanted organs or being treated with chemotherapy. And it's still assumed that for most healthy people it poses no threat that once the parasite gets inside the brain that I just hunkers down inside neurons never again to cause any problems. But there's now several labs, both in Europe and the United States that are challenging that dogma. And they have uncovered a lot of evidence that for a small percentage of people the dormant infection may indeed have adverse consequences. Nobody yet has a handle on what percentage but about 20 percent of all Americans are infected with the parasite. So people's guess is that we're only talking about a small percentage of people who have these adverse responses.

Penn Jillette on Placebo Prayer: Should Atheists Talk to God?

source: Big Think 2016年9月11日
Right before he goes to sleep every night, staunch atheist Penn Jillette does something surprising. He says a little prayer – sort of. Jillette's latest book is "Presto!: How I Made Over 100 Pounds Disappear and Other Magical Tales" (http://goo.gl/jJDkz1).

Transcript - I very rarely look in this kind of proximity when I’m not sexting. If you want to know how to be a good leader watch Donald Trump and don’t’ do that. Don’t do any of that. I realized recently that I do something very close to prayer. And I don’t want to show any disrespect to people by using the word prayer because I know from my friends who are religious that prayer has a supernatural element, that people are actually connecting to a higher power. And I don’t want to show disrespect to that. But I also want to make a little bit of an argument. Sam Harris makes his argument for atheist meditation. I want to make a little bit of an argument for atheist prayer. I do something before I go to sleep at night called Penn’s guild roundup. And Penn’s guild roundup is I go through conversations that I’ve had like tonight before I go to bed I’ll think should I really have made that sexting joke when I was at the Big Think. Should I really have done that? Did that make people uncomfortable. Is that a line. And I’ll run through how I could have done that better.
I say that with no joke. I’ll actually do that. And I run through conversations I’ve had and things I’ve done. One that comes up every night was, you know, should I treat Teller better? And the answer is always no. But I do reflect about it. I do think about it. I also try to think of what I want and how I can get there. Now I’m very fortunate because when I go to my desires they’re not very often material desires because my family is well cared for. I’ve been very lucky and I’ve done well. But I think about – I used to think about my weight and one of the things I used to – and I’m very hesitant to use the word because I don’t want to show disrespect for those who think it really is supernatural. But I would pray to be able to control the watts of my diet. Wouldn’t that be great? And I try to run through how to do that and I do believe with God there’s a lot of throwing the baby out with the bathwater. I’m not referring to baptism there. I’m referring to the fact that so much of the social and personal elements of religion are really good. I would say maybe more than good, maybe very close to necessary.

Graham Harman on Metaphysics, Art, & Speculative Realism

source: Philosophical Overdose 2013年4月22日
In this talk, Graham Harman discusses two types of philosophical paradox pertaining to human knowledge, and the relation that art has to both. The first is one discussed by Meno and Socrates, resulting in the Socratic claim that we both have and do not have the truth. Our inability to gain direct access to reality is what justifies philosophy as philosophia (the love of wisdom rather than wisdom itself) and rules out both mathematism and scientism as defensible models of philosophy. The second paradox is the familiar dispute over whether truth is discovered or constructed. Given that no direct access to reality is possible, the observation of truth itself seems to be part of the truth, yet the observer also cannot create truth ex nihilo. These two paradoxes are not new, but if we look at them carefully, we can draw new conclusions from them. In this way, a different light is shed on the relation between philosophy and art.
Graham Harman is part of the object-oriented and speculative realist movement. For Harman, objects aren't reducible to mere bundles of properties/qualities, or their various relations to and effects on, other objects. Instead, Harman understands the nature of objects as real independent substances in their own right, over and above their manifold appearances and qualities. Otherwise, objects lose their underlying identity as something real, and end up being mere appearances, analyzable in terms of something else more fundamental. This object-oriented approach leads Harman to a pluralistic vision of the world, in contrast to the more holistic and monistic tendency which has characterized much traditional and contemporary philosophy.
