What is Enlightenment?

什么是启蒙？An Answer to the Question: What is Enlightenment? (1784) IMMANUEL KANT

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 in lack of resolve and courage to use it without guidance from another. Sapere Aude! [dare to know] "Have courage to use your own understanding!"--that is the motto of enlightenment.

Laziness and cowardice are the reasons why so great a proportion of men, long after nature has released them from alien guidance (natura-liter maiorennes), nonetheless gladly remain in lifelong immaturity, and why it is so easy for others to establish themselves as their guardians. It is so easy to be immature. If I have a book to serve as my understanding, a pastor to serve as my conscience, a physician to determine my diet for me, and so on, I need not exert myself at all. I need not think, if only I can pay: others will readily undertake the irksome work for me. The guardians who have so benevolently taken over the supervision of men have carefully seen to it that the far greatest part of them (including the entire fair sex) regard taking the step to maturity as very dangerous, not to mention difficult. Having first made their domestic livestock dumb, and having carefully made sure that these docile creatures will not take a single step without the go-cart to which they are harnessed, these guardians then show them the danger that threatens them, should they attempt to walk alone. Now this danger is not actually so great, for after falling a few times they would in the end certainly learn to walk; but an example of this kind makes men timid and usually frightens them out of all further attempts.

Thus, it is difficult for any individual man to work himself out of the immaturity that has all but become his nature. He has even become fond of this state and for the time being is actually incapable of using his own understanding, for no one has ever allowed him to attempt it. Rules and formulas, those mechanical aids to the rational use, or rather misuse, of his natural gifts, are the shackles of a permanent immaturity. Whoever threw them off would still make only an uncertain leap over the smallest ditch, since he is unaccustomed to this kind of free movement. Consequently, only a few have succeeded, by cultivating their own minds, in freeing themselves from immaturity and pursuing a secure course.

But that the public should enlighten itself is more likely; indeed, if it is only allowed freedom, enlightenment is almost inevitable. For even among the entrenched guardians of the great masses a few will always think for themselves, a few who, after having themselves thrown off the yoke of immaturity, will spread the spirit of a rational appreciation for both their own worth and for each person's calling to think for himself. But it should be particularly noted that if a public that was first placed in this yoke by the guardians is suitably aroused by some of those who are altogether incapable of enlightenment, it may force the guardians themselves to remain under the yoke--so pernicious is it to instill prejudices, for they finally take revenge upon their originators, or on their descendants. Thus a public can only attain enlightenment slowly. Perhaps a revolution can overthrow autocratic despotism and profiteering or power-grabbing oppression, but it can never truly reform a manner of thinking; instead, new prejudices, just like the old ones they replace, will serve as a leash for the great unthinking mass.

Nothing is required for this enlightenment, however, except freedom; and the freedom in question is the least harmful of all, namely, the freedom to use reason publicly in all matters. But on all sides I hear: "Do not argue!" The officer says, "Do not argue, drill!" The tax man says, "Do not argue, pay!" The pastor says, "Do not argue, believe!" (Only one ruler in the World says, "Argue as much as you want and about what you want, but obey!") In this we have examples of pervasive restrictions on freedom. But which restriction hinders enlightenment and which does not, but instead actually advances it? I reply: The public use of one's reason must always be free, and it alone can bring about enlightenment among mankind; the private use of reason may, however, often be very narrowly restricted, without otherwise hindering the progress of enlightenment. By the public use of one's own reason I understand the use that anyone as a scholar makes of reason before the entire literate world. I call the private use of reason that which a person may make in a civic post or office that has been entrusted to him. Now in many affairs conducted in the interests of a community, a certain mechanism is required by means of which some of its members must conduct themselves in an entirely passive manner so that through an artificial unanimity the government may guide them toward public ends, or at least prevent them from destroying such ends. Here one certainly must not argue, instead one must obey. However, insofar as this part of the machine also regards himself as a member of the community as a whole, or even of the world community, and as a consequence addresses the public in the role of a scholar, in the proper sense of that term, he can most certainly argue, without thereby harming the affairs for which as a passive member he is partly responsible. Thus it would be disastrous if an officer on duty who was given a command by his superior were to question the appropriateness or utility of the order. He must obey. But as a scholar he cannot be justly constrained from making comments about errors in military service, or from placing them before the public for its judgment. The citizen cannot refuse to pay the taxes imposed on him; indeed, impertinent criticism of such levies, when they should be paid by him, can be punished as a scandal (since it can lead to widespread insubordination). But the same person does not act contrary to civic duty when, as a scholar, he publicly expresses his thoughts regarding the impropriety or even injustice of such taxes. Likewise a pastor is bound to instruct his catecumens and congregation in accordance with the symbol of the church he serves, for he was appointed on that condition. But as a scholar he has complete freedom, indeed even the calling, to impart to the public all of his carefully considered and well-intentioned thoughts concerning mistaken aspects of that symbol, as well as his suggestions for the better arrangement of religious and church matters. Nothing in this can weigh on his conscience. What he teaches in consequence of his office as a servant of the church he sets out as something with regard to which he has no discretion to teach in accord with his own lights; rather, he offers it under the direction and in the name of another. He will say, "Our church teaches this or that and these are the demonstrations it uses." He thereby extracts for his congregation all practical uses from precepts to which he would not himself subscribe with complete conviction, but whose presentation he can nonetheless undertake, since it is not entirely impossible that truth lies hidden in them, and, in any case, nothing contrary to the very nature of religion is to be found in them. If he believed he could find anything of the latter sort in them, he could not in good conscience serve in his position; he would have to resign. Thus an appointed teacher's use of his reason for the sake of his congregation is merely private, because, however large the congregation is, this use is always only domestic; in this regard, as a priest, he is not free and cannot be such because he is acting under instructions from someone else. By contrast, the cleric--as a scholar who speaks through his writings to the public as such, i.e., the world--enjoys in this public use of reason an unrestricted freedom to use his own rational capacities and to speak his own mind. For that the (spiritual) guardians of a people should themselves be immature is an absurdity that would insure the perpetuation of absurdities.
