Not nature, but the "genius of mankind," has knotted the hangman's noose with which it can execute itself at any moment.

I had always been impressed by the fact that there are surprisingly many individuals who never use their minds if they can avoid it, and yet are not stupid, and an equal number who obviously do use their minds but in an amazingly stupid way.

In studying the history of the human mind one is impressed again and again by the fact that its growth keeps pace with a widening range of consciousness, and that each step forward is an extremely painful and laborious achievement. One could almost say that nothing is more hateful to man than to give up the smallest particle of unconsciousness. He has a profound fear of the unknown. Ask anybody who has ever tried to introduce new ideas!

In the last analysis, the essential thing is the life of individual. This alone makes history, here alone do the great transformations take place, and the whole future, the whole history of the world, ultimately springs as a gigantic summation from these hidden source in individuals.

The serious problems in life...are never fully solved. If ever they should appear to be so it is a sure sign that something has been lost. The meaning and purpose of a problem seem to lie not in its solution but in our working at it incessantly.

The debt we owe to the play of imagination is incalculable.

To find out what is truly individual in ourselves, profound reflection is needed; and suddenly we realize how uncommonly difficult the discovery of individuality is.
