Faith is the state of being ultimately concerned.

In the depth of the anxiety of having to die is the anxiety of being eternally forgotten.

Doubt is not the opposite of faith; it is one element of faith.

There is faith in every serious doubt, namely, the faith in the truth as such, even if the only truth we can express is our lack of truth.

The character of human life, like the character of the human condition, like the character of all life, is "ambiguity": the inseparable mixture of good and evil, the true and false, the creative and destructive forces-both individual and social.

The basic anxiety, the anxiety of a finite being about the threat of non-being, cannot be eliminated. It belongs to existence itself.

Love is the infinite which is given to the finite.
