IMMANUEL KANT

An Answer to the Question: "What is Enlightenment?"

Konigsberg in Prussia, 30th September, 1784.


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. The
motto of enlightenment is therefore: 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 and for the duty of all men to think for themselves. The
remarkable thing about this is that if the public, which was previously put
under this yoke by the guardians, is suitably stirred up by some of the latter
who are incapable of enlightenment, it may subsequently compel the guardians
themselves to remain under the yoke. For it is very harmful to propagate
prejudices, because they finally avenge themselves on the very people who first
encouraged them (or whose predecessors did so). Thus a public can only achieve
enlightenment slowly. A revolution may well put an end to autocratic despotism
and to rapacious or power-seeking oppression, but it will never produce a true
reform in ways of thinking. Instead, new prejudices, like the ones they
replaced, will serve as a leash to control the great unthinking mass.

For enlightenment of this kind, all that is needed is freedom. And the freedom
in question is the most innocuous form of all: freedom to make public use of
one's reason in all matters. But I hear on all sides the cry: Don't argue! The
officer says: Don't argue, get on parade! The tax-official: Don't argue, pay!
The clergyman: Don't argue, believe! (Only one ruler in the world says: Argue as
much as you like and about whatever you like, but obey!). All this means
restrictions on freedom everywhere. But which sort of restriction prevents
enlightenment, and which, instead of hindering it, can actually promote it ? I
reply: The public use of man's reason must always be free, and it alone can
bring about enlightenment among men; the private use of reason may quite often
be very narrowly restricted, however, without undue hindrance to the progress of
enlightenment. But by the public use of one's own reason I mean that use which
anyone may make of it as a man of learning addressing the entire reading public.
What I term the private use of reason is that which a person may make of it in a
particular civil post or office with which he is entrusted. . . . .


If it is now asked whether we at present live in an enlightened age, the answer
is: No, but we do live in an age of enlightenment. As things are at present, we
still have a long way to go before men as a whole can be in a position (or can
ever be put into a position) of using their own understanding confidently and
well in religious matters, without outside guidance. But we do have distinct
indications that the way is now being cleared for them to work freely in this
direction, and that the obstacles to universal enlightenment, to man's emergence
from his self-incurred immaturity, are gradually becoming fewer. In this respect
our age is the age of enlightenment, the century of Frederick the Great, King of Prussia..
