What is Enlightenment?

But would a society of pastors, perhaps a church assembly or venerable presbytery (as those among the Dutch call themselves), not be justified in binding itself by oath to a certain unalterable symbol in order to secure a constant guardianship over each of its members and through them over the people, and this for all time: I say that this is wholly impossible. Such a contract, whose intention is to preclude forever all further enlightenment of the human race, is absolutely null and void, even if it should be ratified by the supreme power, by parliaments, and by the most solemn peace treaties. One age cannot bind itself, and thus conspire, to place a succeeding one in a condition whereby it would be impossible for the later age to expand its knowledge (particularly where it is so very important), to rid itself of errors,and generally to increase its enlightenment. That would be a crime against human nature, whose essential destiny lies precisely in such progress; subsequent generations are thus completely justified in dismissing such agreements as unauthorized and criminal. The criterion of everything that can be agreed upon as a law by a people lies in this question: Can a people impose such a law on itself? Now it might be possible, in anticipation of a better state of affairs, to introduce a provisional order for a specific, short time, all the while giving all citizens, especially clergy, in their role as scholars, the freedom to comment publicly, i.e., in writing, on the present institution's shortcomings. The provisional order might last until insight into the nature of these matters had become so widespread and obvious that the combined (if not unanimous) voices of the populace could propose to the crown that it take under its protection those congregations that, in accord with their newly gained insight, had organized themselves under altered religious institutions, but without interfering with those wishing to allow matters to remain as before. However, it is absolutely forbidden that they unite into a religious organization that nobody may for the duration of a man's lifetime publicly question, for so do-ing would deny, render fruitless, and make detrimental to succeeding generations an era in man's progress toward improvement. A man may put off enlightenment with regard to what he ought to know, though only for a short time and for his own person; but to renounce it for himself, or, even more, for subsequent generations, is to violate and trample man's divine rights underfoot. And what a people may not decree for itself may still less be imposed on it by a monarch, for his lawgiving authority rests on his unification of the people's collective will in his own. If he only sees to it that all genuine or purported improvement is consonant with civil order, he can allow his subjects to do what they find necessary to their spiritual well-being, which is not his affair. However, he must prevent anyone from forcibly interfering with another's working as best he can to determine and promote his well-being. It detracts from his own majesty when he interferes in these matters, since the writings in which his subjects attempt to clarify their insights lend value to his conception of governance. This holds whether he acts from his own highest insight--whereby he calls upon himself the reproach, "Caesar non eat supra grammaticos."'--as well as, indeed even more, when he despoils his highest authority by supporting the spiritual despotism of some tyrants in his state over his other subjects.

If it is now asked, "Do we presently live in an enlightened age?" the answer is, "No, but we do live in an age of enlightenment." As matters now stand, a great deal is still lacking in order for men as a whole to be, or even to put themselves into a position to be able without external guidance to apply understanding confidently to religious issues. But we do have clear indications that the way is now being opened for men to proceed freely in this direction and that the obstacles to general enlightenment--to their release from their self-imposed immaturity--are gradually diminishing. In this regard, this age is the age of enlightenment, the century of Frederick.

A prince who does not find it beneath him to say that he takes it to be his duty to prescribe nothing, but rather to allow men complete freedom in religious matters--who thereby renounces the arrogant title of tolerance--is himself enlightened and deserves to be praised by a grateful present and by posterity as the first, at least where the government is concerned, to release the human race from immaturity and to leave everyone free to use his own reason in all matters of conscience. Under his rule, venerable pastors, in their role as scholars and without prejudice to their official duties, may freely and openly set out for the world's scrutiny their judgments and views, even where these occasionally differ from the accepted symbol. Still greater freedom is afforded to those who are not restricted by an official post. This spirit of freedom is expanding even where it must struggle against the external obstacles of governments that misunderstand their own function. Such governments are illuminated by the example that the existence of freedom need not give cause for the least concern regarding public order and harmony in the commonwealth. If only they refrain from inventing artifices to keep themselves in it, men will gradually raise themselves from barbarism.

I have focused on religious matters in setting out my main point concerning enlightenment, i.e., man's emergence from self-imposed immaturity, first because our rulers have no interest in assuming the role of their subjects' guardians with respect to the arts and sciences, and secondly because that form of immaturity is both the most pernicious and disgraceful of all. But the manner of thinking of a head of state who favors religious enlightenment goes even further, for he realizes that there is no danger to his legislation in allowing his subjects to use reason publicly and to set before the world their thoughts concerning better formulations of his laws, even if this involves frank criticism of legislation currently in effect. We have before us a shining example, with respect to which no monarch surpasses the one whom we honor.

But only a ruler who is himself enlightened and has no dread of shadows, yet who likewise has a well-disciplined, numerous army to guarantee public peace, can say what no republic may dare, namely: "Argue as much as you want and about what you want, but obey!" Here as elsewhere, when things are considered in broad perspective, a strange, unexpected pattern in human affairs reveals itself, one in which almost everything is paradoxical. A greater degree of civil freedom seems advantageous to a people's spiritual freedom; yet the former established impassable boundaries for the latter; conversely, a lesser degree of civil freedom provides enough room for all fully to expand their abilities. Thus, once nature has removed the hard shell from this kernel for which she has most fondly cared, namely, the inclination to and vocation for free thinking, the kernel gradually reacts on a people's mentality (whereby they become increasingly able to act freely), and it finally even influences the principles of government, which finds that it can profit by treating men, who are now more than machines, in accord with their dignity.
