For any single individual to work himself out of the life under tutelage which has become almost his nature is very difficult. He has come to be fond of this state, and he is for the present really incapable of making use of his reason, for no one has ever let him try it out. Statutes and formulas, those mechanical tools of the rational employment or rather misemployment of his natural gifts, are the fetters of an everlasting tutelage. Whoever throws them off makes only an uncertain leap over the narrowest ditch because he is not accustomed to that kind of free motion. Therefore, there are few who have succeeded by their own exercise of mind both in freeing themselves from incompetence and in achieving a steady pace.
But that the public should enlighten itself is more possible; indeed, if only freedom is granted enlightenment is almost sure to follow. For there will always be some independent thinkers, even among the established guardians of the great masses, who, after throwing off the yoke of tutelage from their own shoulders, will disseminate the spirit of the rational appreciation of both their own worth and every man's vocation for thinking for himself. But be it noted that the public, which has first been brought under this yoke by their guardians, forces the guardians themselves to remain bound when it is incited to do so by some of the guardians who are themselves capable of some enlightenment – so harmful is it to implant prejudices, for they later take vengeance on their cultivators or on their descendants. Thus the public can only slowly attain enlightenment. Perhaps a fall of personal despotism or of avaricious or tyrannical oppression may be accomplished by revolution, but never a true reform in ways of thinking. Rather, new prejudices will serve as well as old ones to harness the great unthinking masses.
For this enlightenment, however, nothing is required but freedom, and indeed the most harmless among all the things to which this term can properly be applied. It is the freedom to make public use of one's reason at every point. But I hear on all sides, "Do not argue!" The officer says: "Do not argue but drill!" The tax collector: "Do not argue but pay!" The cleric: "Do not argue but believe!" Only one prince in the world says, "Argue as much as you will, and about what you will, but obey!" Everywhere there is restriction on freedom.
