Cover art for Central lyrics by John Frusciante

If something is nothing it must not be something in any possible way points out the paradox that is nothingness. Nothing doesn't exist because just assigning it the term 'nothing' makes it something. But at the same time you can't say it doesn't exist because we try to explain things that are un-designatable with designatable terms like 'it is nothing' or 'it doesn't exist. I know it sounds like bull but once you apply some philosophy you can understand it. That's my two cents anyway...

Also, I think 'central' perfectly describes the concepts in this song, when presented with two sides like below and above, you realize that they are one in the same and you are central to the two sides. Something can be right below my feet but at the same time be far off because of the relativity we put on it. Anything that could one day be is as real as what i'm saying is pretty simple, time doesn't really exist and just because something exists on the physical plane doesn't make it any more 'real' than something in someone's head....
