How do you know what you know? It's a simple question but trying to answer it reveals something very deep about our culture: an almost neurotic fixation on doubt. Why are we like this? Where did it begin? Join me as we embark on one of the most defining topics of our era.

For being supposedly non-religious, secular people are surprisingly interested in weird phenomenon, everything from A.I. worship to UFOs to drug-induced mystical experiences. It's almost like we're building new religions—but how new are they, really?

Can we build a god out of A.I.? As it turns out, the ancients were already doing much the same thing, and the "science of idol-making" is a recognized technique going back many centuries. Is what we're doing with A.I. the same? Are idols real creatures?

Because modern people tend to think of ourselves as irreligious or secular, it makes the rise of new religious movements based on worshipping computers seem almost wacky and unserious. But what if I told you that this was always the goal of the modern era?

Increasing technology has also led to increasing anxiety. It's not merely that all the dystopian science-fiction stories are coming true; it's the bizarre return of ancient, religious impulses and desires now fused to our tech development—a new frontier of techno-paganism.

Are sorcerers and scientists really aiming at the same thing? People from CS Lewis to Oswald Spengler have answered this question in the affirmative. Spengler in particular, characterizes our age as "Faustian". Are we really sorcerers? Find out on today's episode.

If the gods were real but fallen, where are they now? Given a very basic set of Christian assumptions, it's not that far-fetched to imagine that the gods are still around, still very much crave worship and slaves, and having been working with humans to build a new Babel.

The second element we need to understand in our relationship to knowledge and technology is the fall of the gods and all the stories about the fallen gods giving knowledge to mankind.

As our technological power grows, so do our concerns about the future. In this new series, Dr. Zac explores the historical and spiritual context surrounding man's relationship to technology, starting with the idea of the Dark Logos: an anti-Christ relationship to creation.

What is Marxism, really? Is it compatible with Christianity? Is it more freeing or less? What exactly is "real" Marxism? Today, we pull up the root ideas of the Communist Manifesto to see which ideas are at the core of Marx's thinking.
