To venture causes anxiety, but not to venture is to lose one's self.... And to venture in the highest is precisely to be conscious of one's self.

Learning to know anxiety is an adventure which every man has to affront if he would not go to perdition either by not having known anxiety or by sinking under it. He therefore who has leaned rightly to be in anxiety has learned the most important thing.

The question is not "To be or not to be," it is what we should be until we are not.

...the reason for [this age's] anxiety and unrest is because in one direction, 'truth' increases in scope and quantity - via science and technology - while in the other, certainty and confidence steadily decline. Our age is a master in developing truths while being wholly indifferent to certitude. It lacks confidence in the good.

I am so stupid that I cannot understand philosophy; the antithesis of this is that philosophy is so clever that it cannot comprehend my stupidity. These antitheses are mediated in a higher unity; in our common stupidity.

...the greatest thing each person can do is to give himself to God utterly and unconditionally - weaknesses, fears, and all. For God loves obedience more than good intentions or second-best offerings, which are all too often made under the guise of weakness.

Life is lived forwards, but understood backwards.
