That Which Is Not: Plato, Kant, & Sellars (Ray Brassier)

A Day in the Life of the Brain: the neuroscience of consciousness from dawn 'til dusk
source: London School of Economics and Political Science 2016年11月8日
Date: Thursday 3 November 2016
Time: 6.30-8pm
Venue: Old Theatre, Old Building
Speaker: Baroness Greenfield
Chair: Dr Frederic Basso
Consciousness is the ultimate miracle - and enigma. However most people take this subjective inner state for granted without ever reflecting on what could possibly be happening in their brain each day of their waking lives. This non-specialist talk will investigate this deeply fascinating question from the perspective of neuroscience, by exploring how objective events in the brain are realised as subjective experience. We follow a day in the life of a generic person (‘you’) as you wake up, walk the dog, have breakfast, work and return to a family with a variety of mental conditions. By the time we see ‘you’ ending your day in dreams, we will still not have solved how the water of objective brain mechanisms transform into the wine of subjective experience: but along the way we will have gained insights into cutting edge neuroscience, as well as contemplating the future of such research, for eventually really understanding consciousness.
Susan Greenfield is a research scientist, author and broadcaster based in Oxford. She has held research fellowships in the Department of Physiology Oxford, the College de France Paris, and NYU Medical Center New York. She has since been awarded 32 Honorary Degrees from British and foreign universities and heads a multi-disciplinary research group exploring novel brain mechanisms linked to neurodegenerative diseases such Alzheimer’s and Parkinson’s. She is a Senior Research Fellow at Lincoln College, Oxford and has currently co-founded a biotech company developing a novel approach to neurodegenerative disorders (Neuro-Bio Ltd). Her latest book is A Day in the Life of the Brain.
Frédéric Basso is Assistant Professor in Economic Psychology at the Department of Psychological and Behavioural Science of LSE, was a fellow of the Ecole Normale Supérieure de Cachan (France) in Law, Economics and Management and took the Agrégation in Economics and Management. His work is rooted in the grounded cognition theoretical framework and how laboratory paradigms can transfer to real-world phenomena in order to design evidence-informed policy thanks to field research.

Zarathustra's Indo-European Legacy (Jason Reza Jorjani)
source: New Thinking Allowed 2016年11月6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 reviews scholarship that places Zarathustra more than eight thousands years ago, at a time when Indo-European culture had not divided into Vedic, Greco-Roman, and European branches. Zarathustra himself was a religious reformer who endeavored to invert the older relationships between the gods and titans. Jorjani suggests that the spread of Indo-European culture was an effort to avoid the reforms of Zarathustra. Nevertheless, Zarathustra’s teachings survived intact through the order of the Magi he created. Eventually, Zoroastrianism became the state religion of the Persian empire. It also exerted a significant influence on Mahayana Buddhism and Christianity.
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.

Subcultural growing up: a re-embrace of dominant gender codes?

Subcultural growing up: a re-embrace of dominant gender codes?
Paul Hodkinson
(Surrey)
With a particular focus upon gender, this presentation explores the shifting orientation of goths as they collectively became older whilst retaining a strong identification with their subculture. While in some respects the retention of subcultural attachments rendered them distinctive, their collective ageing was often accompanied by a gradual re-orientation towards roles and understanding consistent with hegemonic adulthood. This re-embrace of dominant roles was particularly pronounced with respect to gender and sexuality, I suggest, with transgressive forms of dress, practice and identity often beginning to give more way to more familiar and traditional appearances and orientations, particularly with respect to marriage and children. That this apparent drift back to the mainstream took place collectively as part of an ongoing subcultural engagement rather than as a result of individuals relinquishing their attachment is of particular interest, I suggest, amount to something of a realignment of the subculture itself, or at least of its older cohorts.

Slavoj Žižek – Against Tolerance - Think Again Podcast #72
source: Big Think 2016年11月13日
Since 2008, Big Think has been sharing big ideas from creative and curious minds. The Think Again podcast takes us out of our comfort zone, surprising our guests and Jason Gots, your host, with unexpected conversation starters from Big Think’s interview archives.
Slavoj Žižek is a Hegelian philosopher, Lacanian psychoanalist, and political activist. He’s the international director of the Birbeck Institute for the Humanities, and Global Distinguished Professor of German at New York University. His newest book is Refugees, Terror, and Other Troubles with the Neighbors: Against the Double Blackmail.
In this spirited, wide-ranging discussion, the voluble Žižek talks about why he hates being called the "Elvis of philosophy," argues against liberal notions of tolerance, and promises to arrange for Jason to get cigarettes and whiskey in the gulag when the revolution comes.

How does your body know what time it is? - Marco A. Sotomayor

Being able to sense time helps us do everything from waking and sleeping to knowing precisely when to catch a ball that’s hurtling towards us. And we owe all these abilities to an interconnected system of timekeepers in our brains. But how do they work? Marco A. Sotomayor details how human bodies naturally tell time.

In 2015–2016, the Next in Science series focused on frontiers in astronomy and astrophysics. Scholars discussed new interdisciplinary research on what the structure of the universe tells us about particle interactions, gravitational waves from circling black holes, magnetic fields in intergalactic space, and the possibility of life on exoplanets.

Charles W. Clark - Over the Rainbow: The Other World Seen by Animals
source: Institute for Quantum Computing 2016年11月18日
Much of what we understand about the world comes from our eyes, which sense the colours from red to violet that are expressed in the rainbow.
Yet we know that this patch of colours is just a small island in the vast electromagnetic spectrum, which extends from radio waves to gamma rays. Two invisible regions of great importance to us are those just over and just under the rainbow - the infrared and ultraviolet, respectively. These were discovered about 200 years ago in inspired experiments that anyone can understand, originally conducted by Frederick William Herschel and Johann Wilhelm Ritter. Only recently has it come to be understood that a variety of animals live in a visual world totally unfamiliar to us, particularly in the ultraviolet.
The ultraviolet is a realm fundamentally ruled by quantum physics, and the scene of a discovery that laid the foundation of the quantum theory of matter. The birds and the bees seem unaware of this, but they make fruitful use of it every day.
