Substack Essays

A year-long inquiry into the deepest questions: What is reality? How do we know what's true? What threatens the future? Who are we beneath our roles? How do we live well? Over 52 weeks, across 6 phases—Cosmology, Existential Risk, Epistemology, Self & Identity, Ethics & Meaning, and Integration—these essays move from the cosmos to consciousness to responsibility. Written with rigor, grounded in lived experience, honoring both wonder and precision. For accomplished adults asking what it all means

Not as abstract philosophy, but as practical inquiry for the second half of your life.
