Not less strong than the will to truth must be the will to sincerity. Only an age, which can show the courage of sincerity, can possess truth, which works as a spiritual force within it.
Albert SchweitzerYou know of the disease in Central Africa called sleeping sickness. . . . There also exists a sleeping sickness of the soul. Its most dangerous aspect is that one is unaware of its coming. That is why you have to be careful. As soon as you notice the slightest sign of indifference, the moment you become aware of the loss of a certain seriousness, of longing, of enthusiasm and zest, take it as a warning. You should realize your soul suffers if you live superficially.
Albert SchweitzerMan has become a superman ... because he not only disposes oinnate, physical forces, but because he is in command ... olatent forces in nature and because he can put them to his service.... But the essential fact we must surely all feel in our hearts ... is that we are becoming inhuman in proportion as we become supermen.
