Join Freethinker Podcast host Edouard Tahmizian in this 45-minute interview with Rational Science podcaster Bill Gaede about the conceivability of 4-dimensional spatial cubes—hypercubes or tesseracts—and his fascinating former life as a Cuban spy. After noting his intellectual "falling out" with Carl Sagan over his atheism, his reliance on mathematical physics and the modern conception of the scientific method, and his Polyannish vision of humanity's future, Gaede explains how the mathematical concept of dimensions differs from the physicist's concept of them. Sagan, for example, conceptualizes a 2-D square as a shadow of a 3-D cube, and goes on to conceptualize a tesseract as the 3-D shadow of a 4-D hypercube. But is such a hypothetical entity physically conceivable? If time is conceived of as the fourth dimension that connects the perpendicular lines in our visual representations of a tesseract, then the tesseract actually involves nested times (when rotated or moving), such that you really have two dimensions of time added (for 5 dimensions, not 4), rendering it conceptually impossible. In the second half of the interview, Gaede talks about his life in Argentina before he worked as a manager for Advanced Micro Devices (AMD) in California, passing trade secrets on to the Cuban government from the mid-1960s until 1979, before turning himself in to the CIA in 1992 and then doing counterintelligence as a double agent for the FBI at Intel, passing on disinformation back to the Cubans thereafter. Gaede recounts the fascinating story of how AMD's discovery of his betrayal ultimately led to his cover being blown. Check out this fascinating dive into the conceivability of purely mathematical concepts that dovetails into the perils of life as an industrial spy!

Join host Edouard Tahmizian in this about 30-minute interview with returning Cypress College philosophy professor Jason Thibodeau as they outline the fascinating properties of a 4-dimensional spatial cube, or tesseract, by first considering how a creature living in Flatland, a 2-dimensional universe consisting of only length and width, would react to an intersection with that universe by a 3rd-dimensional object or entity. With this analogy to higher-dimensional space in mind, the interlocutors consider how we 3-Drs would react to the intervention of an 4-D being into our 3-D universe. Carl Sagan had suggested that although a Flatlander would not be able to perceive the 3-dimensional height of a 3-D creature, Flatlanders might be able to perceive its 2-dimensional shadow. The discussion turns to whether or not Sagan was right about this: would a 2-D creature actually be able to perceive anything from a 3-D object or entity? If so, what would it be able to perceive? Would it even be conceptually possible for a 3-Dr to exist in a 2-D space, or for a 4-Dr to exist in a 3-D space? If not a 4th spatial dimension, what is it that massive objects curve when they curve spacetime, according to Einstein's theory of general relativity Check out this mind-blowing discussion of modality, conceivability, and possibility!

Join host Edouard Tahmizian in this 40-minute interview with Richard Schoenig, a retired philosophy professor at San Antonio College who's published unique contributions to the philosophy of religion on original sin, the unfairness of Heaven, the objectivity of ethics in a naturalistic universe, and arguments from evil against the existence of God. In the first half of the interview, the interlocutors tackle whether God is the origin of evil per Edouard's "God is Either the Efficient or Final Cause of Evil" (and why—a là French Enlightenment encyclopedist Denis Diderot—God seems to care more about his apples than his children). Then the interlocutors turn to how the Garden of Eden story (and the original sin moral of it) is the edifice of Christianity since without it, salvation from Hell is not necessary in the first place (i.e., Christianity posits the disease so that it can sell you the cure). Finally, Schoenig canvasses the many human beings who, according to Western monotheism, were unable to achieve salvation through no fault of their own—such as those who died in utero, before the age of accountability, with mental handicaps, before Jesus (or other human messengers who delivered the purported requirements of salvation) even existed, or without ever having heard those requirements—whom Schoenig points out constitute the vast majority of human beings that have ever existed. Schoenig notes that attempts to ensure the fairness of salvation by loosening the requirements for the otherwise "unabled" to obtain it simply shift the unfairness of salvation on to the "abled." Unorthodox alternatives like universalism and postmortem-opportunity proposals raise their own vexing problems. Check out this in-depth interview on a fascinating "big picture" critique of Western monotheism!

Join host Edouard Tahmizian in this 25-minute interview with Bruno V., the world-renowned video game music remixer known for his use of diverse musical styles across artists and musical eras. Edouard and Bruno canvass Bruno's influences, his Metalltool project on social media, his guitar work and use of synthesizers, his remixing process, how composers can improve the quality of their music, the tracks that he covers, how he does the longer tracks, how he pays tribute to the soundtracks that he grew up with, and more. Take a peek into the behind-the-scenes world of video game music and keep an ear out for Bruno V.'s upcoming original compositions soon to be posted on his YouTube channel!

Join host Edouard Tahmizian in this twenty-five-minute return interview with Vincent Torley, the skeptical Catholic and former intelligent design proponent who wrote the blog series An A-Z of Unanswered Objections to Christianity, on the issue of whether or not the theological problems that arise from the existence of an inclination to sin under either compatibilist or libertarian notions of free will are insurmountable. The interlocutors canvass various unsuccessful attempts to solve the problem before focusing on whether introducing the notion of first- and second-order desires could give a theological out for why human beings have an inclination to sin in the first place. The discussion then turns to whether or not the way that we conceive of ourselves, or the inferiority of God’s creatures compared to himself, could dissolve the problem. Tune in for this in-depth analysis of attempts to get out of a central theological conundrum!

Join host Edouard Tahmizian in this twenty-minute return interview with Keith Augustine, Executive Director & Editor-in-Chief of Internet Infidels, as they review the five main kinds of parapsychological evidence for life after death, the most persuasive of those sources and their weaknesses, and the chiefly (but not wholly) neuroscientific evidence against life after death. The interlocutors then canvass the importance of weighing the total available evidence rather than just some particular subset of it. Check out this succinct interview with our illustrious DMCA Agent!

Join host Edouard Tahmizian in this half-hour return interview with esteemed Jesus Seminar scholar John Dominic Crossan as they canvass Crossan's thoughts on the 50s-60s CE Q source, why Crossan thinks that the later apocryphal Gospel of Thomas is reflective of an earlier oral tradition (e.g., the fact that roughly one-third of the sayings of Jesus in the Gospel of Thomas are also in Q, in different orders, suggesting a common 40s CE oral tradition informing both), how this hypothesized oral tradition approaches the earliest writings of Paul (30s CE), and what Crossan takes to be a good example of an authentic saying of Jesus (namely, the parable that God's kingdom on Earth is like a mustard seed, which is found in Q, Mark, and Thomas). Tune in for this fantastic interview with a leading biblical scholar about historians' attempts to reconstruct the origins of the Gospels!

Tune in to Edouard Tahmizian's 20-minute interview with Aron Ra about three common creationist objections to Darwinian evolution. First, Aron Ra surveys concepts of abiogenesis from the 1860s to present as they show up in creationist arguments. Next, he responds to creationist arguments from information/complexity (e.g., that there is digital information recorded in our DNA that could not have arisen by natural causes). He then criticizes the claim that there are missing transitional fossils, or 'gaps' in the fossil record, as simply factually inaccurate, before turning to the biological implausibility of the Noah's Ark story. Check out this brief but informative interview!

Join host Edouard Tahmizian in this twenty-minute follow-up interview with New Testament scholar Dennis R. MacDonald on his forthcoming 2-volume reference work Epic Tragedy and the Gospels (on the literary background to gospels that were never intended to be read as histories), the scholarship of Robyn Faith Walsh on mimesis (mythologizing Jesus), the misappropriation of his work by fellow atheists, the Q source and the synoptic problem, and much more. Tune in for this engaging interview with a long-established man of letters!

Join host Edouard Tahmizian in this half-hour follow-up interview with Cypress College philosophy professor Jason Thibodeau as they survey various moral arguments for the existence of God and explain how arguments that chief features of morality point to the divine fall flat. First, Thibodeau notes that the argument that the existence of moral value presupposes the existence of God misfires. Next, he points out out that arguments that we cannot have knowledge of (presumed nonnatural) moral properties without divine assistance simply do not stand up to scrutiny. Finally, he considers a kind of Kantian moral argument that behaving morally only makes sense if good people are rewarded and evil ones are punished in a divinely organized afterlife. Both interlocutors agree that there has to be some independent standard of goodness, otherwise anyone could just define whatever one's nature happens to be as good, no matter how harmful that nature. Thibodeau then tries to flesh out this first kind of moral argument by suggesting that the 'odd' feature of morality that it exploits is that moral obligations are in authoritative, but notes that inserting God anywhere in the discussion does not provide the needed authoritativeness of morality. Both interlocutors then go on to note the ways in which all roads lead to moral subjectivism if God taken to be the source of morality. Tune in for this wide-ranging interview on the nature of morality!

Pick up where you left off at the end of Part I and return to host Edouard Tahmizian in the second 20-minute part of his two-part follow-up interview with esteemed biblical scholar Robert M. Price. The interlocutors go on to discuss whether the earliest Christians also believed in something like Calvinist predestination and which New Testament typologies (correspondences between Old Testament figures and New Testament one), if any, Price prefers. The discussion then turns to Price's forthcoming book The Gospels Behind the Gospels, his response to C. S. Lewis titled Merely Christianity, his When Gospels Collide on contradictions between the Gospel accounts, his Judaizing Jesus, his forthcoming Not Peace, But a Sword, his dabbling in writing fiction, and much more!

In this first half-hour of a two-part follow-up interview with esteemed biblical scholar Robert M. Price, host Edouard Tahmizian queries Price about his recent anthology edited with John W. Loftus, Varieties of Jesus Mythicism: Did He Even Exist? They canvass the role of Jungian mythical archetypes as a kind of script for rituals/rites of passage, Price's take on the scholarship of Robyn Faith Walsh and the historical plausibility of her thesis that educated Hellenistic writers composed the New Testament, whether there were pre-Gospel narratives that were more consistent than the canonical Gospels and exploited by them (in themes like Jesus as the returned Elijah, Jesus as the new Moses, Jesus as a magician, and so on, and by portraying competitors to Jesus as servants of him), and the Gnostic understanding of salvation. Tune in to this animated conversation about fascinating ideas, and then be sure to tune in to Part II, too!

Join host Edouard Tahmizian in this half-hour follow-up interview with Internet Infidels President John MacDonald about why he thinks that the canonical Gospels do not support the idea that Jesus died as a kind of stand-in for us sinners (most clearly evidenced in the Gospel of Luke), what the historical Jesus would've thought about removing circumcision as a requirement for becoming a Christian, the alternative Gnostic understanding of salvation, how the gospel of Mark suggests that the historical Jesus would've had no inkling of the concept that his eventual death might serve as a substitute punishment for the sins of all humankind, and how the historical Jesus' understanding of love differed from the ancient Greek concept of it. MacDonald also compares the societal fall-out following Socrates' execution in Plato's dialogues to that anticipated by the historical Jesus, explains how the idea that Jesus died for our sins makes little sense not only because substituting one person for another's crimes is morally absurd, but because most of us haven't committed any sins that warrant capital punishment, and offers his take on Richard Carrier's defense of Jesus mythicism. Check out this historical and philosophical exploration of one of the core claims of modern Christianity (and the partial transcript of it on the Secular Frontier).

In this half-hour follow-up interview with biblical scholar John Dominic Crossan about his just released book Render Unto Caesar: The Struggle Over Christ and Culture in the New Testament, host Edouard Tahmizian queries Crossan about what it meant for first-century Christians to "render unto Caesar the things that are Caesar's, and unto God the things that are God's." Crossan explains why he reads the Gospels as being constituted by parables that were originally composed in order to emphasize the points that the Gospel-depicted Jesus wanted to really drive home to his followers (e.g., that not all Samaritans are bad in the parable of the Good Samaritan), the idea being that a parable puts the mental work of thinking about the moral of a story on to the listener, forcing him/her to really engage an issue rather than simply passively register it. In the ancient world, Crossan explains, the penalty for failing to solve a riddle was standardly depicted as death (because getting the facts wrong can produce irrevocable catastrophic consequences); so likewise in the Gospels, the failure to understand a parable could cost a person his/her salvation from Hell. They also canvass how the medieval misunderstanding of the literal/metaphorical distinction led to outlandish readings of the Catholic doctrine of transubstantiation, whether or not Jesus (or Paul) 'predicted' that the end of days would occur in the disciples' lifetimes, and much more! Check out this fantastic interview with a world-class biblical scholar framing a lot of these issues from a fascinating perspective!

Join host Edouard Tahmizian in this 40-minute interview with Dan Barker, co-director of the Freedom from Religion Foundation and co-founder of The Clergy Project, about his over 35 years of freethought activism, his forthcoming projects, what improbable events would meet the theological definition of a miracle, how to weigh evidence and what extraordinary claims require extraordinary evidence actually means in the context of miracle claims, the tendency of some Christian debaters to argue for a generic "mere theism" rather than the existence of the Christian God, and more! Check out this easygoing discussion with a funny and all-around personable freethought icon.
