Philosophy-Latin Connection of the Day

Immanuel Kant (1724-1804), Prussian (German, more or less; nit-pickers on this point reveal themselves as perhaps too well-read in European history) philosopher known for the development of deontological ethics and transcendental idealism (look 'em up, folks, they're fascinating).

Anyway, in his 1784 work "An Answer to the Question: What is Enlightenment?", Kant appropriates as a rallying-cry of sorts a Latin phrase, as follows:

Enlightenment is man's emergence from his self-imposed immaturity. Immaturity
is the inability to use one's understanding without guidance from another. This
immaturity is self-imposed when its cause lies not in lack of understanding, but
in lack of resolve and courage to use it without guidance from another. Sapere
Aude! "Have courage to use your own understanding!"--that is the
motto of enlightenment.
