We need something to shock us out of our past beliefs if we are to change them. Otherwise, we are stuck in the past. We speak the world into a reality we only understand within our own minds. And, when we hear any reality spoken we can validate it and agree with one another only if we know the words and what they mean. We cannot understand that for which we have not yet the words to assign meaning.
Reality depends on linguistic ability.
No one can comprehend anything until they are able to give it meaning. We validate our comprehensions with words. And are unable to recognize what we cannot put into words. An unrecognizable thing remains a mystery as though it does not exist. A thing must always be explainable in some way or another.
