I've spoken somewhat extensively on this before, but it is my belief that more or less all thinking in the deep, primal levels of unconsciousness is done through connections and images. It is based upon an intuitive understanding of reality. Language is an abstraction, a projection of these raw ideas into the higher logical order. In language, the personal depth of understanding is exchanged for the ability to communicate and collaborate with others in a way others will understand because they all use roughly the same words and definitions.
