Existence is a selective blindness. Use 'blindness' as paradigmatic of any sense, e.g. 'deafness', 'tastelessness' etc. We notice one side of the thing-boundary at the expense of paying less attention to the other side. ... Were we to pay equal attention to both sides, we would have to attribute to them equal value, and then the thing-boundary would disappear. ... You cannot have it both ways. Either you can see an apparent universe by being selectively blind , or you can see it all equally in which case it must disappear and so must you. Since both in reality are equally possible, but no more than possible, (the laws of form are not more than the laws of the possible), there is really nothing to choose between them.
