Professor Fukanō, the famous scientist, has embarked on a new challenge – piloting around the world in a plane of his own design. There’s just one problem: there's not enough fuel to complete the journey. Luckily, there are two other planes to help. Can you help the professor fly for the whole trip and achieve his dream, without anyone running out of fuel and crashing? Judd A. Schorr shows how.

The Significance of Self-Consciousness in Idealist Theories of Logic by Robert B. Pippin
source: Philosophical Overdose 2016年8月12日
In this talk, Robert B. Pippin discusses the thought of German Idealists like Kant and Hegel in connection with their theories of logic or judgment/thought. Robert B. Pippin is the Evelyn Stefansson Nef Distinguished Service Professor in the John U. Nef Committee on Social Thought, the Department of Philosophy, and the College at the University of Chicago. He is the author of several books on German idealism, including Kant’s Theory of Form (1982), Hegel’s Idealism: The Satisfactions of Self-Consciousness (1989), Modernism as a Philosophical Problem (1991), and Hegel’s Practical Philosophy (2008). He has also written on literature (Henry James and Modern Moral Life (2000)) and film (Hollywood Westerns and American Myth (2010). His most recent books are Nietzsche, Psychology, and First Philosophy (2010), Hegel on Self-Consciousness (2011), and Fatalism in American Film Noir: Some Cinematic Philosophy (2012), and Kunst als Philosophie: Hegel und die Philosophie der bildlichen Moderne (2012). He has been visiting professor at universities in Amsterdam, Jena, Frankfurt, and at the Collège de France. He is a past winner of the Mellon Distinguished Achievement Award in the Humanities, is a fellow of the American Academy of Arts and Sciences, and is a member of The American Philosophical Society.

Werewolf Cults in Ancient Times with P. Sufenas Virius Lupus
source: New Thinking Allowed 2016年10月31日
P. Sufenas Virius Lupus (his spiritual name) is a practicing polytheist and scholar. He is author of A Serpent Path Primer, Ephesia Grammata: Ancient History and Modern Practice, The Phillupic Hymns, The Syncretisms of Antinous, and other devotional books. Under his legal name of Phillip Bernhardt-House, he is author of Werewolves, Magical Hounds, and Dog-Headed Men in Celtic Literature. He is on the social science faculty at Skagit Valley College in Mount Vernon, Washington.
Here he notes that, while the idea of the werewolf may seem spooky, it entails shamanistic practices similar to those found in Native American wolf clans. The Egyptians worshipped the god, Anubis, who had a human form and a canine head. He was a psychopomp, or initiator into the depths of the psyche. In different, ancient traditions ritual practices associated with the wolf and certain other animals were relegated to young men who lived on the margins of their societies. They often served as an early warning system to protect those societies from invaders. Their werewolf cult rituals were a rite of passage as they became reintegrated into their societies.
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.

Psychiatry in Context: the Problem of Degeneration in Brazil
Cristiana Fachinetti
(Fiocruz)
This paper aims to analyse the circulation of the concept of degeneration in the first half of the twentieth century. More precisely, I'll discuss the appropriation of the concept by psychiatrists who were members of the Brazilian League of Mental Hygiene. In this process, I want to demonstrate the selection of some theories made by local psychiatrists from the vast existing psychological repertoire, in order to consider the appropriation choices in relation to the social, political and scientific context of the period. Several studies have indicated the central role of the concept of reception for the analysis of science in different context from which they were produced. However, as Roelcke, Weindling and Westwood (2010) show, international knowledge transfers often end up being perceived as neutral operations, failing to consider local regulations in the process. I therefore propose, in agreement with the authors, that concepts and practices are adopted in one country for particular reasons, and this particular selection is intended to boost expansion strategies of professional skills and application of new practices and technologies that allow the solution of local scientific and social issues. It is from this framework that I'll seek to present the theories that guided the understanding of degeneration in Brazilian population at the beginning of the twentieth century, its impact to psychopathology, as well as theoretical solutions found by local psychiatry considering regeneration.

Jenny Blake: "Pivot: The Only Move That Matters is Your Next One" | Talk...
source: Talks at Google 2016年10月26日
Jenny Blake, author of Life After College and former career development program manager at Google, reveals how to methodically make your next career move by doubling down on what is already working.
Careers are not linear, predictable ladders any longer; they are fluid trajectories. No matter our age, life stage, bank account balance, or seniority, we are all being asked to navigate career changes much more frequently than in years past. The average employee tenure in America is just four to five years, and even those roles change dramatically within that time. Our economy now demands that we create businesses and careers based on creativity, growth, and impact. In this dynamic world of work, the only move that matters is your next one.

Designing better schools
source: University of Oxford 2016年10月25日
Hau Ming Tse, Research Fellow in the Department of Education, as well as students and teachers from Northfleet Technology College, talk about how the design of their new school building has affected learning.
The new school building was designed by architects, teachers and students to ensure that their modern style of teaching and learning was reflected in the building itself.
Design Matters is a project led by Harry Daniels, Professor of Education in Oxford’s Department of Education. The AHRC funded project investigates the effects of newly designed schools on their users, particularly students and teachers. This addresses an important policy issue but also has implications for architectural practice, educational theory and methodology. Visit http://designmatters.education.ox.ac.uk

The Costs of Exclusion: How Gender Inequality Stymies Global Development
The Problem of Free Will (Peter Van Inwagen)
source: Philosophical Overdose 2013年2月28日
Peter Van Inwagen discusses the problem of free will. On the one hand, if the universe is deterministic, then everything that happens is causally necessitated by events of the distant past which took place long before we ever were even born. But we have no power over what took place in the distant past, so how can we have control over the future if it is necessitated by such?! On the other hand, however, if determinism is false, some events will be without any sufficient cause or reason which explains why they happened rather than something else. But such causal and explanatory gaps involve nothing more than sheer chance and randomness; and introducing chance and randomness in actions hardly makes them count as "free". Therefore, it seems that free will is impossible either way, regardless of whether determinism is true or not. It's hard to see how the concept of free will is even coherent!
"Among the grandest of philosophical puzzles is a riddle about moral responsibility. Almost all of us believe that each one of us is, has been, or will be responsible for at least some of our behavior. But how can this be so if determinism is true and all our thoughts, decisions, choices, and actions are simply droplets in a river of deterministic events that began its flow long, long before we were ever born? The specter of determinism, as it were, devours agents, for if determinism is true, then arguably we never initiate or control our actions; there is no driver in the driver's seat; we are simply one transitional link in an extended deterministic chain originating long before our time. The puzzle is tantalizingly gripping and ever so perplexing — because even if determinism is false, responsibility seems impossible: how can we be morally accountable for behavior that issues from an "actional pathway" in which there is an indeterministic break? Such a break might free us from domination or regulation by the past, but how can it possibly help to ensure that the reins of control are now in our hands?"
This talk is part of the Faraday Institute lectures from Cambridge University.
The Practical Applications of Precognition, Part Two: Ongoing Research, with Marty Rosenblatt
source: New Thinking Allowed 2016年1月16日
Marty Rosenblatt, MS, is a computational physicist who spent his career working in the military and industrial sectors. He is the president of the Applied Precognition Project.
Here he discusses his work with the Applied Precognition Project. For more than a decade he has been steadfastly endeavoring to apply, and continually improve, the associative remote viewing (ARV) methodology. He describes the different approaches used by the many dozen participants who form unique groups. He shares the statistical successes of the method.
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 serves as dean of transformational psychology at the University of Philosophical Research. He teaches parapsychology for ministers in training with the Centers for Spiritual Living through the Holmes Institute. 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.

Margaret Atwood – The Good, The Bad, and The Stupid – Think Again Podcas...
source: Big Think 2016年10月30日
Today's guest is novelist, essayist, poet, and as of late, comic-book writer Margaret Atwood. She’s also got some really funny mini-comics about bad interviews, so Jason tries extra-hard to bring his a-game here. She’s the Booker prize winning author of The Blind Assassin, Oryx & Crake, The Handmaid’s Tale, and around 40 other beloved books. Her latest, Hag-Seed, is a total and delightfully wicked reimagining of Shakespeare’s The Tempest.
In this episode Margaret talks with Jason about genomes in the cloud, Bob Dylan's Nobel prize, the elusiveness of dead authors, and why technology's a three-edged sword.
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.
