The Firth Memorial Lectureship was founded by the Reverend John d'ewe Evelyn Firth in memory of his father, John Benjamin Firth, Historian of Nottingham and his mother Helena Gertrude Firth. The lecturer is appointed biennially by the Council of the University on the recommendation of the Senate of the University, and under the terms of the Trust he delivers a public lecture or lectures on some aspect of the Christian Faith in relation to contemporary problems.
In February 2012, Professor Terry Eagleton delivered the latest Firth Lectures entitled; "Culture and the Death of God". The lectures explored the interaction between critical theory and religion in modern society, subjects on which Professor Eagleton has written and lectured extensively over the past 40 years.

Alasdair MacIntyre: On Having Survived Academic Moral Philosophy (1-4)

source: Eidos84      2010年11月29日
On the 6-8 March 2009 the UCD School of Philosophy (whose expertise in the area of continental philosophy was recently ranked as one of the top ten globally by 'The Philosophical Gourmet') hosted the International Society for MacIntyrean Enquiry, at which Alasdair MacIntyre spoke "On Having Survived The Academic Moral Philosophy of the Twentieth Century".
MacIntyre's most famous book, After Virtue (1981), revealed the inconsistencies inherent in the various conflicting ethical systems born out of the Enlightenment, and which for the most part have shaped current social and political values. The common error, he argued in the book, was the failure to adequately ask the most basic of all questions. We ask what is it to be a good manager, teacher, or parent, but neglect to ask: what is it to be a good human being? MacIntyre encouraged his readers to rediscover with Aristotle the centrality of the virtues as concretely exemplifying the goals and practices of the good life.
Alasdair MacIntyre has written widely in philosophy since his first book, Marxism: An Interpretation, appeared in 1953. He is the author of over thirty books, and has made prominent contributions to the history of philosophy, moral philosophy, political theory, philosophy of the social sciences, and philosophy of religion. He has taught at Oxford University, Princeton University, Brandeis University, Boston University, Wellesley College, Vanderbilt University, Duke University, and the University of Notre Dame.

Pedagogy of Game Design

source: Stanford    2016年8月2日
From the Interactive Media & games Seminar Series; Michael John the Program Director of the Games and Playable Media MS Program at UCSC examines Game Design as a field whose time of practice exceeds its pedagogy more than twofold. In addition, many of those currently engaged in game design instruction (such as myself) come not from a teaching background, but from the background of a practitioner. The challenge then is how to take knowledge gained through practice, most of which is intuitive in nature, and generate a structured, thorough, and useful pedagogy of game design.

Reincarnation, Part Two: Cases of Xenoglossy, with Walter Semkiw

source: New Thinking Allowed    2015年12月21日
Walter Semkiw, MD, is founder and president of the Institute for the Integration of Science, Intuition, and Spirit. He is author of Born Again, Return of the Revolutionaries: The Case for Reincarnation and Soul Groups Reunited, and Origin of the Soul and the Purpose of Reincarnation.
Here he points out that some of the strongest evidence supporting the concept of reincarnation comes from rare, but well-documented, cases of xenoglossy – the ability of an individual to speak a language that they did not learn in their present lifetime. He describes some of these cases in detail. He also discusses some of the possible alternative explanations to reincarnation, such as possession, mediumship, or super-ESP. He explains why he feels that reincarnation offers the best explanation. He notes that “announcement dreams” often precede cases that are identified as reincarnation. He also discusses the notion that many people believe themselves to have been famous personalities in a past lifetime.

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.

The Global Connectivity Revolution with Parag Khanna

source: The RSA     2016年8月24日
The Global Connectivity Revolution with strategist and author Parag Khanna. We're accelerating into a future shaped less by countries and more by mega-cities; less by borders and more by connectivity. It is time to reimagine how life is organised on Earth. Leading strategist Parag Khanna shows how the global connectivity revolution - in transport, infrastructure, communications - has upended the ‘geography is destiny’ mantra, and how connectivity, not sovereignty, has become the organising principle of 21st century society.
Watch Parag Khanna, strategist and author of Connectography: Mapping the Global Network Revolution, in our latest RSA Spotlight - the edits which take you straight to the heart of the event! Loved this snippet? Watch the full replay: https://youtu.be/zsf81fHt0_c

Bill Nye: Worrying about the Robo-pocalypse Is a First-World Problem

source: Big Think    2016年8月9日
Bill Nye laughs in the face of the robo-pocalypse. Or more accurately, he laughs at those who worry that AI might run amok. If we build robots that want to kill us, he says, we can just unplug them.
Read more at BigThink.com: http://bigthink.com/videos/bill-nye-o...

So when it comes to artificial intelligence it is fabulous science fiction premise to create a machine that will kill you. And I very much enjoyed Ex Machina where the guy builds these big robots and then there’s trouble. There’s trouble. And I can’t help but think about Colossus, the Forbin Project where they have these computers that control the world’s nuclear arsenals. And then things go wrong, you know. Things just go wrong in science fiction sense. But they remind us that if we can build a computer smart enough to figure out that it needs to kill is we can unplug it. There are two billion people on earth who do not have electricity. They are not concerned about the artificial intelligence computer that decides to crash subway cars and kill people. That’s not their issue. And they don’t even have electricity or clean running water. So while we’re worried about artificial intelligence I hope we also take the bigger picture that none of this happens right now without electricity. And so we still don’t have anything but really primitive means of generating electricity. And I look forward to the day when everybody has clean water and a supply of quality electricity.
And then we can take these meetings about the problems of artificial intelligence. However, are there any viewers, listeners here who have not been to an airport where the train that takes you from terminal B to terminal A is automated, is not automated. Everybody’s been on an automated train, okay. In the developed world, especially the United States. Okay, that’s artificial intelligence. Everybody has used a toilet that’s connected to a sewer system whose valves are controlled by software that somebody wrote that is artificial intelligence. So keep in mind that if we unplug the trains or the sewer system valves the thing will stop. We still control electricity so this apocalyptic view of computers that people write software for to do tasks, repetitive tasks or complicated tasks that no one person can sort out for him or herself. That is not new. I do not see that it’s artificial – I mean that it’s inherently bad. Artificial intelligence is not inherently bad. So just use your judgment everybody. Let’s – we can do this. I worked on three channel autopilots almost 40 years ago. The plane lands itself and humans designed the system. It didn’t come from the sky. It’s artificially intelligent. That’s good. We can do this.
