Phantasie ist unser guter Genius oder unser Dämon. - Immanuel Kant

The public use of a man's reason must be free at all times, and this alone can bring enlightenment among men...

Space is employed as the type even of the concept of time itself, representing it by a line, and its limits — moments — by points. Time, on the other had, approaches more to a universal and rational concept, comprising under its relations all things whatsoever, to wit, space itself, and besides, those accidents which are not comprehended in the relations of space, such as the thoughts of the soul. Again, time, besides this, though it certainly does not dictate the laws of reason, yet constitutes the principal conditions tinder favor of which the mind compares its notions according to the laws of reason. Thus, I cannot judge what is impossible except by predicating a and not-a of the same subject at the same time.

Duas coisas enchem o ânimo de admiração: o céu estrelado acima de mim, e a lei moral dentro de mim; ambas não estão fora do meu horizonte; antes, vejo-as perante mim e religo-as imediatamente com a consciência de minha existência. A primeira começa no lugar que eu ocupo no mundo e no exterior. A segunda começa no meu invisível eu, na minha personalidade e me coloca num mundo que tem a verdadeira infinidade; o que eleva infinitamente o meu valor como inteligência na qual a lei moral me revela uma vida independente da animalidade de todo mundo sensível.
