You always become the thing you fight the most.

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.

It is really the mistake of our age. We think it is enough to discover new things, but we don't realize that knowing more demands a cor­responding development of morality.

Every man carries within himself the eternal image of woman, not the image of this or that particular woman, but a definite feminine image. This image is fundamentally unconscious, a hereditary factor of primordial origin.

The squaring of the circle is a stage on the way to the unconscious, a point of transition leading to a goal lying as yet unformulated beyond it. It is one of those paths to the centre.

The term "self" seems a suitable one for the unconscious substrate whose actual exponent in consciousness is the ego. The ego stands to the self as the moved to the mover, or as object to subject, because the determining factors that radiate outward from the self surround the ego on all sides and are therefore supraordinate to it. The self, like the unconscious, as an a priori existent out of which the ego evolves. It is, so to speak, an unconscious prefiguration of the ego. It is not I who create myself; rather, I happen to myself.

There are as many archetypes as there are typical situations in life. Endless repetition has engraved these experiences into our psychic constitution, not in the forms of images filled with content, but at first only as forms without content, representing merely the possibility of a certain type of perception and action.
