Quote by Immanuel Kant: “Dare to know! Have the courage to use your own understanding.”

Most people outsource their thinking to authorities — priests, rulers, experts — rather than trusting their own minds. Kant is calling on people to break that habit and take responsibility for their own judgements. Growing up intellectually means thinking for yourself, even when it is uncomfortable.

Kant published his essay 'What is Enlightenment?' in 1784, defining the Enlightenment as humanity's emergence from self-imposed intellectual immaturity. He wrote at a time when Prussian censorship was real and the French Revolution was still five years away — the call for intellectual courage was not merely academic.

German philosopher of the Enlightenment whose Critique of Pure Reason attempted to reconcile rationalism and empiricism and transformed Western philosophy. His ethical works, including the Groundwork for the Metaphysics of Morals, introduced the categorical imperative.
