Linear time is objective time is the time of objects. As you are entrapped in the shrinking cell of a lifetime you are object, what you are is the imagination of that objective self with all its novelistic pathos, grandeur and absurdities. But objective time makes no sense, the past and the future are non-existent and the present is infinitesimally small, and besides, all your experiences are registered after they supposedly happened - how do you know when you weren't even there? Subjective time is not linear, it is an opening and an opening up within itself, you can think of it as a kind of movement, but not from A to B, but a welling out, a brimming over, a play or ratios and strictly orthogonal to that imaginary linear time; much more happens in it than ever a narration can capture, without anything strictly happening that is coming and going. Attention couldn't be attention without this other dimension that is not attention - and that, as they say, is why it's called attention.
