I’m so sorry
Notes from “Man And His Symbols” by Carl G. Jung :
Thought forms, universally understandable gestures, and many attitudes follow a pattern that was established long before man developed a reflective consciousness.
It is even conceivable that the early origins of man’s capacity to reflect come from the painful consequences of violent emotional clashes. Let me take, purely as an illustration of this point, the bushman who, in a moment of anger and disappointment at his failure to catch any fish, strangles his much beloved only son, and is then seized with immense regret as he holds the little dead body in his arms. Such a man might remember this moment of pain for ever.
We cannot know whether this kind of experience was actually the initial cause of the development of human consciousness. But there is no doubt that the shock of a similar emotional experience is often needed to make people wake up and pay attention to what they are doing.
