Now, an idea is not the same thing as a fact. A fact is something that is dead, in and of itself. It has no consciousness, no will to power, no motivation, no action. There are billions of dead facts. The internet is a graveyard of dead facts. But an idea that grips a person is alive. It wants to express itself, to live in the world. It is for this reason that the depth psychologists – Freud and Jung paramount among them – insisted that the human psyche was a battleground for ideas.
