"It is never too late to become reasonable and wise"
About this Quote
The subtext snaps into focus if you hear the echo of his 1784 essay “What Is Enlightenment?”: Sapere aude, dare to know. For Kant, immaturity isn’t merely ignorance; it’s the comfortable choice to let others think for you - priests, princes, fashionable opinion, even your own appetites. So the promise in the quote (“you can still become wise”) is inseparable from a provocation (“why haven’t you?”). It’s aimed at the reader’s inertia.
The pairing of “reasonable” and “wise” also matters. Reasonableness is the capacity to submit impulses and beliefs to a common standard - the kind that could be willed as universal law. Wisdom is what happens when that standard is lived, not just admired. Kant is insisting that moral adulthood is practical: it shows up in how you decide, what you excuse, and what you stop outsourcing.
Contextually, this is Enlightenment optimism with a stern spine. Progress isn’t automatic, history doesn’t do your thinking, and no institution will mature you on your behalf. The door is open, but Kant is standing in the doorway, waiting for you to walk through.
