Life is teleology par excellence; it is the intrinsic striving towards a goal, and the living organism is a system of directed aims which seek to fulfill themselves.
Carl JungOur mania for rational explanations obviously has its roots in our fear of metaphysics, for the two were always hostile brothers. Hence, anything unexpected that approaches us from the dark realm is regarded either as coming from outside and, therefore, as real, or else as a hallucination and, therefore, not true. The idea that anything could be real or true which does not come from outside has hardly begun to dawn on contemporary man.
Carl JungA man who has not passed through the inferno of his passions has never overcome them. They then dwell in the house next door, and at any moment a flame may dart out and set fire to his own house. Whenever we give up, leave behind, and forget too much, there is always the danger that the things we have neglected will return with added force.
Carl JungThe difference between the "natural" individuation process, which runs its course unconsciously, and the one that is consciously realized is tremendous. In the first case, consciousness nowhere intervenes; the end remains as dark as the beginning. In the second case, so much darkness comes to light that the personality is permeated with light and consciousness necessarily gains in scope and insight. The encounter between conscious and unconscious has to ensure that the light that shines in the darkness is not only comprehended by the darkness, but comprehends it.
