Saint-Exupéry captures something more unsettling than the mere idea that experiences change us—he suggests we contain multitudes we've never met, dormant versions of ourselves waiting for the right catalyst. The stranger he describes isn't built by the event but *revealed* by it, which means we're never entirely self-made or self-knowing, no matter how carefully we've examined ourselves. A person who discovers they're braver than they believed after standing up to an injustice isn't becoming brave; they're encountering someone who was already there, waiting. This reframes personal growth from achievement into recognition, which should humble us about the certainty we carry regarding who we are.
