I thought of a new concept for the ultimate stuff or what their really is beyond all appearances. People use varying terms for this ultimate stuff: Truth, Reality, The Real, The Absolute, God, the Tao, Nature. But I think there is a paradoxical and almost not-there quality to the ultimate stuff which is not reflected in those concepts. So we need a word that takes up that space - in our minds and on the page - but which doesn't give us much to cling to, since we really can't prove to everyone that we are the ones who've got It (the Truth, the Right way, God). So I propose that we call the ultimate stuff "The Absence". It is a word, a concept, so it is present and yet it refers to what's not there. It's pleasantly or irritatingly paradoxical since it's identifying something that is missing. Maybe the Buddhist notion of emptiness is comparable, but that has to be clarified by saying: "it really means empty/fullness" and "don't think it means nothingness." The term "The Absence" points to something that isn't there.
A drawback to this term could be that it could refer to a previous presence that is now gone because it went away, but that may be ok too.
