Once upon a time men were possessed by devils. Now they are not less obsessed by ideas

The darkness which clings to every personality is the door into the unconscious and the gateway of dreams, from which those two twilight figures, the shadow and the anima, step into our nightly visions or, remaining invisible, take possession of our ego-consciousness.

I am astonished, disappointed, pleased with myself. I am distressed, depressed, rapturous. I am all these things at once, and cannot add up the sum. I am incapable of determining ultimate worth or worthlessness; I have no judgment about myself and my life. There is nothing I am quite sure about. I have no definite convictions - not about anything, really. I know only that I was born and exist, and it seems to me that I have been carried along. I exist on the foundation or something I do not know.

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.
