Rationally Speaking #43 - Women in Skepticism Sep 11, 2011

Show notes

No, this episode is not about "elevatorgate" or the Watson-Dawkins debacle, but we do use these recent (in)famous events as a springboard for a broader discussion of women in skepticism and science. Is there a misogyny problem in the skeptic and atheist communities? Why aren't there more more women involved in these communities? Also, Julia tells us about her own experience as a young woman skeptic.

Rationally Speaking #42 - On the Limits of Reason Aug 28, 2011

Show notes

Following up on their interview with Robert Zaretsky on the dispute between David Hume and Jean-Jacques Rousseau about the limits of reason, Julia and Massimo expand the topic to include a discussion of the failure of "foundational" projects (e.g., the quest for the ultimate bases of scientific reasoning, or of logic and mathematics). Also, our take on a recent paper on the evolutionary psychology of reasoning that has made mainstream news.

Rationally Speaking #41 - Robert Zaretsky on Rousseau, Hume, and the Limits of Human Understanding Aug 14, 2011

Show notes

Imagine a time when a dispute between two philosophers was the talk of high society. That is the time that our guest, Robert Zarertsky, describes in his book "The Philosophers' Quarrel: Rousseau, Hume, and the Limits of Human Understanding." He tells the story of the short and dramatic friendship between Hume and Rousseau. Hume, who championed the progress of the sciences and arts, and Rousseau, who questioned progress, wondering whether it was just another word for moral decay and despair. He also discusses the implications their friendship may have had on the Enlightenment's conceptions of reason and human understanding.

Robert Zaretsky is a professor of French history at the University of Houston Honors College and the Department of History. He has published several books about philosophy and history of philosophy.

Rationally Speaking #40 - Q&A With Massimo and Julia Jul 31, 2011

Show notes

Massimo and Julia answer listeners' questions. In this installment the topics include: what would they teach in a class in critical thinking, their view of analytics vs. continental philosophy, the ethics of profiteering from a drought in examplistan, how do they compartmentalize their rationality, how does modern technology affect the way we think about things, and what is or should be the primary purpose of our species. Also, is there really a rational argument to prove the divine origin of the bible?

Rationally Speaking #39 - The Science and Philosophy of Free Will Jul 17, 2011

Show notes

In this episode we tackle the never ending debate about free will, which David Hume famously defined as "a power of acting or of not acting, according to the determination of the will." We do this with a couple of twists. We begin by examining the concept of free will from the standard philosophical perspective, then ask what — if anything — modern neuroscience can tell us about it, and come back to the interface between philosophy and science to explore how the two approaches may complement each other.

Rationally Speaking #38 - Holden Karnofsky on Evidence-based Philanthropy Jul 03, 2011

Show notes

Our guest Holden Karnofsky joins us to discuss Givewell, the nonprofit organization he founded. Givewell is devoted to investigating charities and NGOs to determine how much of an impact they're having. You could call it "evidence-based philanthropy." He discusses how Givewell evaluates charities, and what the research has to say about various controversies as well as the conventional wisdom in the nonprofit world: Can large charities be efficient? Is the percentage of the donation that goes to expenses really a useful metric? Should we focus on problems closer to home instead of giving to foreign countries? Do microfinance NGOs like Kiva or Grameen Bank live up to their claims? And should or can charities be evaluated objectively?

Rationally Speaking #37 - The Science and Philosophy of Happiness Jun 19, 2011

Show notes

Debates over what's important to happiness — Money? Children? Love? Achievement? — are ancient and universal, but attempts to study the subject empirically are much newer. What have psychologists learned about which factors have a strong effect on people's happiness and which don't? Are parents really less happy than non-parents, and do people return to their happiness "set point" even after extreme events like winning the lottery or becoming paralyzed? We also tackle some of the philosophical questions regarding happiness, such as whether some kinds of happiness are "better" than others, and whether people can be mistaken about their own happiness. But, perhaps the hardest question is: can happiness really be measured?

Rationally Speaking #36 - Why Should We Care About Teaching the Humanities? Jun 05, 2011

Show notes

Universities all around the country are closing programs in the humanities, at least in part because of the increasing widespread attitude that higher education should be treated as a business, and that programs that bring in money in the form of high tuitions from students and external grants are to be prioritized. SUNY Albany, for example, announced in the Fall of 2010 that the departments of French, Italian, Classics, Russian and Theater Arts were being eliminated. So, what is the point of studying languages, literature, history or philosophy? Can we, and perhaps more importantly, should we quantify their value? Can we have universities that focus only on science and marketable skills?

Rationally Speaking #35 - What is Philosophy of Science Good for? May 22, 2011

Show notes

In this episode we explore philosophy of science: What is it about, and should it matter to scientists? Massimo and Julia also discuss some of the most important questions in philosophy of science now, and some historical debates between leading philosophers of science, like Thomas Kuhn and Karl Popper, over how science should or does work.

So is philosophy of science, as Richard Feynman famously quipped, "as useful to scientists as ornithology is to birds?" Or was philosopher Daniel Dennett closer to the truth when he said, "There is no such thing as philosophy-free science, only science whose philosophical baggage is taken on-board unexamined?"

Rationally Speaking #34 - Celebrities and the Damage They Can Do May 08, 2011

Show notes

If the recent hoopla about the royal wedding wasn't enough to remind you, we live in a culture of celebrity, one where famous people command our attention and often pontificate on things they know nothing about. Obvious examples include the nonsense spewed out by Prince Charles about alternative medicine, and the former model Jenny McCarthy and her dangerous notion that vaccines are harmful because they cause autism. But these, of course, are easy targets. What are we to make of Ray Kurzweil (he of Singularity fame), who recently co-authored a book with a homeopath? Or of otherwise savvy political commentator Bill Maher, who doesn't trust vaccines or anything coming from "Western" medicine? And then there are highly respectable intellectuals, like Stephen Hawking, who write off entire fields of inquiry (philosophy, in his case), without apparently knowing much about them.

So what is going on here? Why do so many people listen to Jenny McCarthy? And why do so many bright minds go public with ridiculous notions? Is there a pattern? Can we do something to defend ourselves and the public from the celebrity attack on reason?
