" [...] the really complex and unfamiliar part of the human mind, from which symbols are produced, is still virtually unexplored. It seems almost incredible that though we receive signals from it every night, deciphering these communications seems too tedious for any but a very few people to be bothered with. Man's greatest instrument, his psyche, is little thought of, and it is often directly mistrusted and despised. "It's only psychological" too often means: It is nothing. "
