Faith & Spirit Quote by C. S. Lewis

"Experience: that most brutal of teachers. But you learn, my God do you learn"

About this Quote

Lewis frames experience as pedagogy stripped of gentleness: not the kindly tutor of self-help lore, but a disciplinarian that teaches by bruising. The punch lands in the contrast between “brutal” and “teacher,” a pairing that refuses the comforting idea that growth is optional or curated. Experience, for Lewis, is not knowledge you acquire; it’s knowledge that happens to you, often against your preferences. The colon snaps the sentence into a definition, like a dictionary entry written by someone who’s been through it.

Then he swerves into prayer and astonishment: “my God do you learn.” The phrase reads as both expletive and invocation, and that ambiguity matters. Lewis, a Christian apologist who converted after years of atheism, understood learning as more than skill-building; it’s moral and spiritual reorientation, frequently triggered by pain. The line implies that suffering has an uncanny efficiency: it bypasses rationalizations, shortcuts vanity, forces attention. You can ignore advice; you can’t easily ignore consequence.

The subtext is almost grudging gratitude. He doesn’t romanticize hardship, but he concedes its effectiveness. That concession is the rhetorical trap: you’re invited to admit, privately, that your own most permanent lessons likely didn’t arrive via books or mentors but via humiliation, grief, failure, illness, betrayal - the moments that dismantle the person you thought you were. Lewis’s genius is that he makes the admission feel unsentimental and alive, as if the speaker is still catching his breath after the lesson.
