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

“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 has its own hidden forces which you can only discover by living.”

“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.”

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

“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.”
