Dan Shaw explores why people leave Christianity by probing a deeper issue beneath individual complaints: the search for certainty in a world that feels like an “earthquake.” Using Luc Ferry’s discussion of Descartes, it argues that radical skepticism and “I think, therefore I am” locate certainty inward, a pattern echoed in Greek options like Stoicism (detach to avoid pain) and Epicureanism (dive into pleasure). Dan contrasts this with Rhett McLaughlin’s deconstruction, in which losing the “appetite for certainty” felt liberating, and with his later claim that evangelical faith often demands certainty through assent to doctrinal propositions. The script concludes that certainty isn’t achieved by introspection or institutional authority but is bestowed from outside through the proclaimed gospel—“faith comes by hearing”—especially through Word, baptism, and the Lord’s Supper.
