Was Ist Aufklärung?

Answering the Question: What Is Enlightenment? (German: Beantwortung der Frage: Was ist Aufklärung?) is a 1784 essay by the philosopher Immanuel Kant. In the December 1784 publication of the Berlinische Monatsschrift (Berlin Monthly), edited by Friedrich Gedike and Johann Erich Biester, Kant replied to the question posed a year earlier by the Reverend Johann Friedrich Zöllner, who was also an official in the Prussian government. Zöllner's question was addressed to a broad intellectual public community, in reply to Biester's essay entitled: "Proposal, not to engage the clergy any longer when marriages are conducted" (April 1783) and a number of leading intellectuals replied with essays, of which Kant's is the most famous and has had the most impact. Kant's opening paragraph of the essay is a much-cited definition of a lack of Enlightenment as people's inability to think for themselves due not to their lack of intellect, but lack of courage.

Kant's essay also addressed the causes of a lack of enlightenment and the preconditions necessary to make it possible for people to enlighten themselves. He held it necessary that all church and state paternalism be abolished and people be given the freedom to use their own intellect. Kant praised Frederick II of Prussia for creating these preconditions. Kant focused on religious issues, saying that "our rulers" had less interest in telling citizens what to think in regard to artistic and scientific issues.

Kant answers the question in the first sentence of the essay: "Enlightenment is man's emergence from his self-incurred immaturity." He argues that the immaturity is self-inflicted not from a lack of understanding, but from the lack of courage to use one's reason, intellect, and wisdom without the guidance of another. He exclaims that the motto of enlightenment is "Sapere aude"! – Dare to be wise!

The German word "Unmündigkeit" means not having attained age of majority or legal adulthood. "Unmündig" also means "dependent" or "unfree", and another translation is "tutelage" or "nonage" (the condition of "not [being] of age"). Kant, whose moral philosophy is centred on the concept of autonomy, here distinguishes between a person who is intellectually autonomous and one who keeps him/herself in an intellectually heteronomous, i.e., dependent and immature status.
