One of the main reasons there is so much variation and diversity when it comes to peoples understanding of the universe is to be found in the language which people speak. Our languages are full of wrong concepts, wrong classifications, wrong associations. And the chief thing is that every word can have thousands of different meanings according to the material the speaker has at his disposal and the complex of associations at work in him at the moment. People do not clearly realize to what a degree their language is subjective, that is, what different things each of them says while using the same words. They are not aware that each one of them speaks in a language of his own, understanding other people's language either vaguely or not at all. People have a very firm conviction, or belief, that they speak the same language, and that they understand one another.
I think it's even worse than that; intrapersonally, most of us are internally baffled by our words which are kind of steampunkesque contraptions aiming to encapsulate the shining void of reality. I think most western philosophy has been a kind of mechanic's toolbox for tweaking these words, failing to see that they have failed in their purpose.
