The Wealth of Humans: work, power, and status in the twenty-first century
source: London School of Economics and Political Science (LSE) 2016年9月28日
Speaker(s): Ryan Avent
Chair: Professor Francesco Caselli
Recorded on 26 September 2016 at Old Theatre, Old Building
In his new book, The Wealth of Humans: Work, Power, and Status in the Twenty-First Century, which he will discuss in this talk, Ryan Avent addresses the difficult questions about the increasing abundance of labour and what this means politically, economically and socially for every one of us. The traditional solutions – improved education, wage subsidies, universal basic income – will no longer work as they once did. In order to navigate our way across today’s rapidly transforming economic landscape, Avent argues that we must radically reassess the very idea of how, and why, we work.

Humanity's Greatest Challenges Aren't Technical – They're Human | Nichol Bradford
source: Big Think 2016年9月25日
Maslow's Hierarchy of Needs is incomplete as we commonly know it. Later in his life, Maslow wrote about a stage beyond self-actualization. Nichol Brandford explains how to arrive at this final place.
Read more at BigThink.com: http://bigthink.com/videos/nichol-bra...
Transcript - Many people think that Maslow’s hierarchy of needs stopped with self-actualization. And that’s not actually true. He had another piece that was on top of self-actualization and that was self-transcendence. He just didn’t publish it widely before he passed away. It was something he started working on towards the end and so he published the hierarchy of needs before he finished his work on self-transcendence. He was one of the first people really to track flow and to track some of the more interesting and advanced altered states that human babies can get to. Things that you would find the terminology really similar to things that you’ve heard advanced meditators describe. And so he was working on self-transcendence. And he just didn’t publish it. So there’s actually another level on top of that hierarchy of needs. And so when I think of human psychology I really think of human psychology as a spectrum and it’s not a series of islands or unique locations. It’s really sort of a spectrum. And on one end you have what I call areas that require human support. So this is when people are facing severe stress, severe anxiety and depression. And then in the middle is what I call the human condition. And so that is loneliness, happiness, connection, empathy. The human condition is where we learn how to deal with our first heartbreak and the first time that we fall in love.
The human condition is where we deal with sadness and betrayal and loss. Basically all the things that happen to you as you grow up through life. The full spectrum of human emotion. That is the human condition. And there’s an infinite number of songs on the radio and poems and art that’s about the human condition. So that’s there. And then on this other side which I think really maps to self-transcendence and Maslow’s later work is the part of the people in the world who are really pushing on human psychology and what are the limits? Where are our boundaries? What is the frontier of human psychology? And I think a lot of direction that we get is from the contemplative communities around the world who really have been exploring and pushing on human psychology for as long as humans have been organized. And pushing on what it is, what does it mean to be human. The other day I talked to a guy who now has three Guinness Book records on endurance sports. And he meditates the entire time. And he just swam the English Channel in a Speedo and he meditated the whole time. So, you know, people are using mind training, meditation and other things to push into abilities that right now, today, one could say are limited to the few.

Dialetheism (1-4) by Kane B
source: Kane B 2013年2月15日
Setting the scene for a series on dialetheism, the view that there are true contradictions.
A good introductory article to paraconsistent logics: http://plato.stanford.edu/entries/log...
Dialetheism is the view that there are true contradictions. Much of the literature on dialetheism can be quite technical, but given that it touches on such a fundamental element of philosophy - of reasoning in general - I think it's important to be aware of it. I'm hoping that this series will provide an accessible introduction.
By far the most prominent defender of dialetheism is Graham Priest: he's devoted most of his philosophical career to developing arguments for it. His book "Doubt Truth to be a Liar" is definitely the most accessible introduction to the topic, from what I've read. His earlier book "In Contradiction" has been more influential, but is much more difficult.

Consciousness - Physicalism & Dualism (Papineau & Goff)
source: Philosophical Overdose 2013年2月22日
Philip Goff and David Papineau discuss consciousness and whether it's at bottom something physical or material. Goff rejects physicalism/materialism, Papineau accepts it. In this discussion, they examine the arguments on each side. They consider the causal exclusion argument for physicalism, the much-discussed "knowledge argument" against physicalism, conceptual dualism, explore Goff's own reasons for rejecting physicalism, weigh the dualist arguments of Chalmers and Jackson, discuss Papineau's reasons to reject the transparency of phenomenal concepts, ponder what Levine calls the "explanatory gap", and confront the specter of epiphenomenalism.

Vernon Neppe, MD, PhD, FRSSAf, is a neuropsychiatrist and head of the Pacific Neuropsychiatric Institute in Seattle. He is a former president of the South African Society for Psychical Research. He is author of Cry the Beloved Mind: A Voyage of Hope, Reality Begins with Consciousness: A Paradigm Shift that Works (written with physicist Edward Close), The Déjà Vu Trilogy, and Innovative Psychopharmacotherapy. His professional publications number over 700. Dr Neppe has amplified many of his concepts in two of the websites linked with his work. On www.Brainvoyage.com, his books are amplified. www.VernonNeppe.org is his gateway and includes more information on the Neppe-Close model of the Triadic Distinction Vortical Paradigm.
Here he provides a detailed analysis of a chess match played between a living grandmaster, Victor Korchnoi and an ostensible deceased grandmaster, Géza Maróczy, whose moves were communicated through the auspices of a spiritualist medium using automatic writing. Neppe argues that this is a strong case supporting the hypothesis of survival of consciousness after death. It combines an unusual degree of accurate information with a high level of chess skill, plus aspects of personality.
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.
