“It is perfectly true, as philosophers say, that life must be understood backwards. But they forget the other proposition, that it must be lived forwards.”

“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.”

“Life can only be understood backwards; but it must be lived forwards.”

“What I really lack is to be clear in my mind what I am to do, not what I am to know, except in so far as a certain knowledge must precede every action. The thing is to understand myself, to see what God really wishes me to do: the thing is to find a truth which is true for me, to find the idea for which I can live and die. ... I certainly do not deny that I still recognize an imperative of knowledge and that through it one can work upon men, but it must be taken up into my life, and that is what I now recognize as the most important thing.”

“All this is only fooling, for if it is true that every man must work for his own salvation, then all the prophecies about the future of the world are only valuable and allowable as a recreation, or a joke, like playing bowls or cards.”

“Life's existential tasks have lost the interest of reality; illusion cannot build a sanctuary for the divine growth of inwardness which ripens to decisions. One man is curious about another, every one is undecided, and their way of escape is to say that some one must come who will do something--and then they will bet on him.”

“The task must be made difficult, for only the difficult inspires the noble-hearted.”
