It’s hard to escape the conclusion that the unconscious is laboring under a moral compulsion to educate us. (Moral compulsion? Is he serious?) . . . . The unconscious is concerned with rules but these rules will require your cooperation. The unconscious wants to give guidance to your life in general but it doesn’t care what toothpaste you use. And while the path which it suggests for you may be broad it doesn’t include going over a cliff. We can see this in dreams. Those disturbing dreams which wake us from sleep are purely graphic. No one speaks. These are very old dreams and often troubling. Sometimes a friend can see their meaning where we cannot. The unconscious intends that they be difficult to unravel because it wants us to think about them. To remember them. It doesn’t say that you can’t ask for help. Parables of course often want to resolve themselves into the pictorial. When you first heard of Plato’s cave you set about reconstructing it.
….The unconscious is just not used to giving verbal instructions and is not happy doing so.
. . . The unconscious seems to know a great deal. What does it know about itself? Does it know that it’s going to die? What does it think about that? It appears to represent a gathering of talents rather than just one. It seems unlikely that the itch department is also in charge of math. Can it work on a number of problems at once? Does it only know what we tell it? Or—more plausibly—has it direct access to the outer world? Some of the dreams which it is at pains to assemble for us are no doubt deeply reflective and yet some are quite frivolous. And the fact that it appears to be less than insistent upon our remembering every dream suggests that sometimes it may be working on itself. And is it really so good at solving problems or is it just that it keeps its own counsel about the failures? How does it have this understanding which we might well envy? How might we make inquiries of it? Are you sure?
