The tense native to ontological parsimony is of course the future anterior - 'it will have been'. This needs to encompass everything, including itself. Against this you might find yourself wishing to carry something of the past over into the future, or to import some future resolution back into the past. Or, if not wishing then its opposite, being oppressed by, negative wishing, which amounts to the same thing. Thinking that there is a way to sidestep your own foolishness, or limitedness, being past- or future-oriented, which fixes and solidifies one end of the vector, the doer or the done by. How much of the machinery of thought is dedicated to weaving this kind of scaffold in time, to weaving time itself out of recurrences of desire. The metaphysics of desire is no joke.
