The disease of the hypochondriac consists in this: that certain bodily sensations do not so much indicate a really existing disease in the body as ra… - Immanuel Kant

What is the use of working toward a lawful civic constitution among individuals, i.e., toward the creation of a commonwealth? The same unsociability which drives man to this causes any single commonwealth to stand in unrestricted freedom in relation to others; consequently, each of them must expect from another precisely the evil which oppressed the individuals and forced them to enter into a lawful civic state. The friction among men, the inevitable antagonism, which is a mark of even the largest societies and political bodies, is used by Nature as a means to establish a condition of quiet and security. Through war, through the taxing and never-ending accumulation of armament, through the want which any state, even in peacetime, must suffer internally, Nature forces them to make at first inadequate and tentative attempts; finally, after devastations, revolutions, and even complete exhaustion, she brings them to that which reason could have told them at the beginning and with far less sad experience, to wit, to step from the lawless condition of savages into a league of nations. In a league of nations, even the smallest state could expect security and justice, not from its own power and by its own decrees, but only from this great league of nations … from a united power acting according to decisions reached under the laws of their united will.

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.
