In Immanuel Kant's book 'Kant's critique of pure reason' he describes what the meaning of The Enlightenment is...
'Enlightenment is man's emergence from his self-imposed immaturity, immaturity is the inability to use one's understanding without guidance from another. This immaturity is self-imposed when its cause lies not in lack of understanding, but it in lack of resolve and courage to use it without guidance from another. Supere Aude! (Dare to know). Have courage to use your own understanding!'
