Little in our lives is fundamentally original. Almost every situation we encounter is similar to an immense number of previous situations. These similarities are not limited to the human species. They go back through the history of evolution. For example walking past a dog that feels you are violating its territory raises instincts and actions in the dog that are not so far removed from similar human instincts.
Evolution molds life to respond to recurring situations.
It describes them so they can be directly understood by consciousness. That is part of the value of the I Ching as an intuitive discipline. It strengthens our conscious understanding of the patterns that intuition recognizes. With a better conscious understanding we know more about what to make of these patterns and we can better focus our intuition as a result. You can do a detailed analysis of the state and explain exactly why this history and input produces this response but that is no explanation.
