Breaking representation also breaks the categories. Why does time seem to be linear? Past and future are aspects of experiencing in which their function is to be the setting for the present. The contribution they make in each case is via features and affinities, capabilities and influences and so their saliences are the best ways in which these relationships are organised. The best way is necessarily the way they are; if they were another way, then that would be the best way. They are ways in which things can move in and out of foregrounds, backgrounds and overshadowings, and the movements are too rich to fall on a line, even a life-line. Ask yourself whether the present is really a point, has it ever felt like a point? So the idea of linear time comes from the same place as all received ideas. Any proof that could be offered would be a begging of the question, assuming the expected answer in the terms of the argument. And that too would be of a certain pattern of saliences. You might say that this begs the question too, but that is exactly what is meant.
