An Answer to the Question: What Is Enlightenment?

Enlightenment is man's emergence from his self-incurred immaturity. Immaturity
is the inability to use one's own understanding without the guidance of another.
This immaturity is self-incurred if its cause is not lack of understanding, but
lack of resolution and courage to use it without the guidance of another. Sapere aude! Have courage to use your own
understanding!

Laziness and cowardice are the reasons why such a large proportion of men, even
when nature has long emancipated them from alien guidance (naturaliter
maiorennes), nevertheless gladly remain immature _for life. For the same
reasons, it is all too easy for others to set _themselves up as their guardians.
It is so convenient to be immature! If I have a _book to have understanding in
place of me, a spiritual adviser to have a _conscience for me, a doctor to judge
my diet for me, and so on, I need not make any efforts at all. I need not think,
so long as I can pay; others will soon enough take the tiresome job over for me.
The guardians who have kindly taken upon themselves the work of supervision will
soon see to it that by far the largest part of mankind (including the entire
fair sex) should consider the step forward to maturity not only as difficult but
also as highly dangerous. Having first infatuated their domesticated animals,
and carefully prevented the docile creatures from daring to take a single step
without the leading-strings to which they are tied, they next show them the
danger which threatens them if they try to walk unaided. Now this danger is not
in fact so very great, for they would certainly learn to walk eventually after a
few falls. But an example of this kind is intimidating, and usually frightens
them off from further attempts.
Thus it is difficult for each separate individual to work his way out of the
immaturity which has become almost second nature to him. He has even grown fond
of it and is really incapable for the time being of using his own understanding,
because he was never allowed to make the attempt. Dogmas and formulas, those
mechanical instruments for rational use (or rather misuse) of his natural
endowments, are the ball and chain of his permanent immaturity. And if anyone
did throw them off, he would still be uncertain about jumping over even the
narrowest of trenches, for he would be unaccustomed to free movement of this
kind. Thus only a few, by cultivating the;r own minds, have succeeded in freeing
themselves from immaturity and in continuing boldly on their way.
There is more chance of an entire public enlightening itself. This is indeed
almost inevitable, if only the public concerned is left in freedom. For there
will always be a few who think for themselves, even among those appointed as
guardians of the common mass. Such guardians, once they have themselves thrown
off the yoke of immaturity, will disseminate the spirit of rational respect for
personal value
