Man can only find meaning for his existence in something outside himself.
For the world is in a bad state, but everything will become still worse unless each of us does his best.
Life can be pulled by goals just as surely as it can be pushed by drives.
The struggle for existence is a struggle 'for' something; it is purposeful and only in so being is it meaningful and able to bring meaning into life.
The angels are lost in perpetual contemplation of an infinite glory.
No one can take away my freedom to choose how I will react.
