Thunder is no longer the voice of an angry god... No river contains a spirit... no snake the embodiment of wisdom, no mountain cave the home of a great demon. No voices now speak to man from stones, plants and animals, nor does he speak to them thinking they can hear. His contact with nature has gone, and with it has gone the profound emotional energy that this symbolic connection supplied.

Plato's world of ideas is beautiful.

Our mind has its history, just as our body has its history. You might be just as astonished that man has an appendix, for instance. Does he know he ought to have an appendix? He is just born with it....Our unconscious mind, like our body, is a storehouse of relics and memories of the past. A study of the structure of the unconscious collective mind would reveal the same discoveries as you make in comparative anatomy. We do not need to think that there is anything mystical about it.

You must live life in such a spirit that you make in every moment the best of possibilities.

Man positively needs general ideas and convictions that will give a meaning to his life and enable him to find a place for himself in the universe.

Eternal truth needs a human language that alters with the spirit of the times.

One must be able to let things happen.
