Anxiety is the dizziness of freedom.

Whoever has learned to be anxious in the right way has learned the ultimate.

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.

He who is educated by anxiety is educated by possibility… When such a person, therefore, goes out from the school of possibility, and knows more thoroughly than a child knows the alphabet that he demands of life absolutely nothing, and that terror, perdition, annihilation, dwell next door to every man, and has learned the profitable lesson that every dread which alarms may the next instant become a fact, he will then interpret reality differently…

Anxiety is freedom’s possibility; this anxiety alone is, through faith, absolutely formative, since it consumes all finite ends, discovers all their deceptions.

When the discoveries of possibility are honestly administered, possibility will discover all finitudes but idealize them in the shape of infinity, in anxiety overwhelm the individual, until the individual again overcomes them in the anticipation of faith.

Anxiety can be replaced only by the freedom whose harsh requirements are its cause. Being free requires us to release the brakes that anxiety represents in order to accept and appropriate our proper spiritual fulfillment or perhaps even to recognize, if that is what we in the end believe, that no such prospect is in store.

To venture causes anxiety. Not to venture is to lose oneself.
