For most of human history, infectious diseases have wreaked havoc on humans. But beginning in the late 18th century, more and more of us beat back illness by getting immunized with vaccines. Today, vaccines are -- or should be – a part of every thinking person’s health regimen.

But exactly what are vaccines and how do they work? How are they tested?

Joining Jim in this episode of Point of Inquiry is immunologist David Miles. David teaches at London School of Hygiene and Tropical Medicine, and is the author of How Vaccines Work: A layman's guide to the history and science of vaccines and vaccination.

Learn about both the history and present state of immunology from this fascinating discussion.

When a business owner, ex-marine, and retired peace office is questioned and later arrested for what appear to be bigoted reasons, there should be recourse in our system of justice to right such a wrong. But Steve Hill is having a hell of a time finding help with his well-documented struggles.

Should the fact that he is a black man and a member of the Satanic Temple enter into whether he is treated fairly or not – or even represented in court? Not if justice is blind and secular.

Jim chats with Steve about his multi-year battle with law enforcement authorities and the courts to achieve satisfaction and find justice.

Almost 30 percent of the U.S. population is religiously unaffiliated, but only a fraction of those so-called "Nones" identify as atheist or agnostic. Fewer still feel comfortable revealing to the people in their lives that they don't believe in God. Kate Cohen was one of those people. Though she had determined that God was a human-made fiction from a young age, the challenges of navigating social pressures and familial expectations led her to "play along" with God and religion well into adulthood. But then she had children of her own, and something changed. She decided to stop pretending to believe.

On this episode, Free Inquiry Editor Paul Fidalgo talks to Cohen about her new book, We of Little Faith: Why I Stopped Pretending to Believe (And Maybe You Should Too). It's the story of her evolution from closeted atheist to truth-teller that illustrates the rewards of honesty, as well as a call to action for fellow nonbelievers to embrace the truth, both for their own sake and the country’s.

Kate Cohen is a columnist for the Washington Post, and a chapter from her new book is excerpted in the February/March 2024 issue of Free Inquiry magazine. 

Members of Gen X and older grew up in an America in which being religious was the default and atheism was, as best, on the fringes. A lot has changed in the last couple of decades, and for many Millennials and members of Gen Z, being nonreligious is really no big deal. Folks in younger generations are accustomed to living among people of various religious and ethnic backgrounds, and as the percentage of Nones (the religiously unaffiliated) has risen, relatively few young Americans feel the need to explicitly identify as a nonbeliever. So what does that mean for atheism and building a secular humanist community?

Sarah An Myers is a regular contributor to Free Inquiry magazine, as well as Psychology Today and other publications. She has been giving a lot of thought to these questions, and in this conversation with Free Inquiry editor Paul Fidalgo, she discusses what secular humanism might be able to offer those who don't jibe with traditional religion but are tolerant and curious about other forms of spirituality. Can a community of the rational embrace a little irrationality?

In 2019, Academy Award-nominated documentary filmmaker Scott Kennedy was working on a film about the years-long anti-vaxxer movement. Filming with top public health officials–including Tony Fauci–as well as rare interviews with anti-vaccine activists who were persuading parents by the millions to refuse vaccines for their children. And then COVID hit, and further fueled immunization fears that would kill countless people. Scott chronicled the subsequent events from day one in his film, Shot in the Arm, released in late 2023.

Jim's conversation with Scott about his film, his process, and his other work is testimony to the fact that there are still documentarians out there with integrity, and use their skills to bring out the truth. Visit the documentary's website for more information.

The U.S. Supreme Court -- that over sixty years ago ruled against state-led prayer in public schools --  has swung back the other way with a vengeance. The ultra-conservative majority on the current court has reversed 60 years of progress and put the rights of non-believers in jeopardy.

In this episode, Jim Underdown speaks to Nick Little, former Director of CFI's Legal department, and Eddie Tabash, Chair of the CFI Board of Directors. The two lawyers talk about the state of the court, recent decisions, and the problematic future for secular Americans.
