what is enlightenment ?
is man’s emergence from his self-incurred imaturity .
is the inability to use one’s own understanding without the guidance of another .
is self-incurred if its cause is not lack of understanding ,
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!
Konigsberg in Prussia, 30th September, 1784.
