Immanuel Kant’s definition of Enlightenment:

“The Enlightenment represents man’s emergence from a self-inflicted state of minority. A minor is one who is incapable of making use of his understanding without guidance from someone else. This minority is self-inflicted whenever its cause lies not in lack of understanding, but in a lack of the determination and courage to make use of it without the guidance of another. Sapere aude! (Latin for “Dare to Know!” “Dare to be wise!” “Have courage to use your own reason!”) Have the courage to make use of your own understanding, is therefore the word of the Enlightenment.”
