Even truth can be deceptive, whatever its appearance. - Karl Jaspers

There exists among men, because they are men, a solidarity through which each shares responsibility for every injustice and every wrong committed in the world, and especially for crimes that are committed in his presence or of which he cannot be ignorant. If I do not do whatever I can to prevent them, I am an accomplice in them. If I have not risked my life in order to prevent the murder of other men, if I have stood silent, I feel guilty in a sense that cannot in any adequate fashion be understood juridically, or politically, or morally ... That I am still alive after such things have been done weighs on me as a guilt that cannot be expiated.

I approach the presentation of Kierkegaard with some trepidation. Next to Nietzsche, or rather, prior to Nietzsche, I consider him to be the most important thinker of our post-Kantian age. With Goethe and Hegel, an epoch had reached its conclusion, and our prevalent way of thinking — that is, the positivistic, natural-scientific one — cannot really be considered as philosophy.
