What if the most obvious things you believe… aren’t facts at all, but assumptions you’ve never questioned?

Like fish unaware of the water they swim in, we move through a world shaped by invisible ideas—ideas so pervasive they feel like reality itself.

In Of Geometry and Jesus, Chris Spark takes you outside the fishbowl.

Moving freely across science, philosophy, religion, anthropology, and lived experience, these essays challenge the boundaries we take for granted. What if reason depends on faith? What if culture doesn’t just influence what we think—but what we actually see? What if the divisions we rely on—between science and spirituality, rational and mystical, everyday and divine—aren’t real at all?

In these essays, you’ll explore:

•Why every system of reason—including mathematics—rests on unprovable assumptions

•How culture and expectation shape not just belief, but perception itself

•Why the boundaries between science, spirituality, and everyday experience may be illusions

•The hidden role of myth, art, and personality in shaping what we call truth

•What it means to experience yourself not as separate, but as part of a living whole

From the hidden assumptions behind mathematics to the spiritual axioms underlying modern culture, Spark reveals how the worlds we inhabit are built on ideas we rarely examine.

These essays are not abstract theory. They are an invitation to experience the world differently.

To feel yourself not as separate and divided, but as part of a coherent, meaningful whole—one in which Western civilization is only one way of seeing among many.
