If humans are basically good, why do we keep breaking our own rules?

In Episode 4, we look at Chapter 3 of Mere Christianity, where C.S. Lewis presses on an uncomfortable reality: we all appeal to a moral standard we don’t actually live up to.

This isn’t a sermon and it’s not a guilt trip. It’s an honest look at why moral progress is harder than it sounds—and why “just be better” never quite works.

Whether you’re religious, skeptical, or undecided, this episode raises questions most of us recognize but rarely sit with.

In Chapter 2 of Mere Christianity, C.S. Lewis responds to two common objections to the idea of a real moral law:
that morality is just herd instinct, and
that it’s nothing more than social conditioning.
In this video, we walk through why Lewis thinks neither explanation actually works, how our moral decisions involve choosing between instincts, and why appeals to fairness and obligation point to something deeper than biology or culture. These objections sound convincing at first—but Lewis carefully shows where they fall apart.
This chapter pushes us past surface-level explanations and asks a harder question: if morality isn’t just instinct or society, what is it?
👇 Which objection do you hear most often today—instinct or conditioning?

In this video, we unpack what Lewis calls the Law of Human Nature, why our everyday arguments matter more than we think, and how this points to the existence of objective moral truth. This chapter lays the foundation for the entire book and raises a question we can’t avoid: where does our sense of right and wrong come from?
If you’ve ever wondered whether morality is just a matter of opinion—or something deeper—this chapter is the perfect place to start.
👇 Let me know in the comments: do you think right and wrong are real, or just personal preference?
