New theory... The **only** intellectual thing that seperates us from the rest of animals is the ability to do math.
All the things we dont usually think of as math but we associate with being human is in fact math... language is math, logic is math, its all math... language is simply our ontology we use to express logic as symbols we can express. We have a natural intuitive understanding (well some of us, to some extent) of prepositional logic and language is more or less a manifestation of that.
