It is the duty of the human understanding to understand that there are things which it cannot understand.

It is quite true what Philosophy says: that Life must be understood backwards. But that makes one forget the other saying: that it must be lived—forwards. The more one ponders this, the more it comes to mean that life in the temporal existence never becomes quite intelligible, precisely because at no moment can I find complete quiet to take the backward- looking position.

No one is so terribly deceived as he who does not himself suspect it.

...he who always hopes for the best becomes old, deceived by life, and he who is always prepared for the worst becomes old prematurely; but he who has faith, retains eternal youth.

Faith is precisely the paradox that the single individual as the single individual is higher than the universal, is justified before it, not as inferior to it but superior - yet in such a way, please note, that it is the single individual who, after being subordinate as the single individual to the universal, now by means of the universal becomes the single individual who as the single individual is superior, that the single individual as the single individual stands in an absolute relation to the absolute.

Don't forget to love yourself.

This is all that I've known for certain, that God is love. Even if I have been mistaken on this or that point: God is nevertheless love.
