Enlightenment is man's leaving his self-caused immaturity. Immaturity is the incapacity to use one's intelligence without the guidance of another. Such immaturity is self-caused if it is not caused by lack of intelligence, but by lack of determination and courage to use one's intelligence without being guided by another. Sapere Aude! Have the courage to use your own intelligence! is therefore the motto of the enlightenment.
Man is in pursuit of two goals: he is looking for happinesse and, being by essence empty ("étant vide par essence", Fr.), he is trying to fill (or take up, - "remplir", Fr.) his life; the latter reason play a more considerable role than we ordinarily think. What we take for vainglory, ambition, love of power and riches (or wealth), is often, indeed, a need to mask this emptiness, a need to let one's hair down (or to live it up), to put oneself on a false scent or trail. (de se donner le change", Fr.)
Whether a man chooses to tell the truth in long sentences or short jokes is a problem analogous to whether he chooses to tell the truth in French or in German.
It was not the visible sun, but its invisible Creator who consecrated this day for us, when the Virgin Mother, fertile of womb and integral in her virginity, brought him forth, made visible for us, by whom, when he was invisible, she too was created. A Virgin conceiving, a Virgin bearing, a Virgin pregnant, a Virgin bringing forth, a Virgin perpetual. Why do you wonder at this, O man?
Who is a good man? He who keeps the decrees of the fathers, and both human and divine laws.
[Lat., Vir bonus est quis?
Qui consulta patrum, qui leges juraque servat.]
