As we experience our own thoughts and memories, we “know” what they mean, but they do not exist as readily explainable thoughts and recollections. If we want to share them with others, we need to translate them into language. This task is also accomplished by the neocortex, using pattern recognizers trained with patterns that we have learned for the purpose of using language. Language is itself highly hierarchical and evolved to take advantage of the hierarchical nature of the neocortex, which in turn reflects the hierarchical nature of reality.
