For time in both “directions” is an analogical projection of the moment just experienced. i.e. the future is the past projected and so is the present.
Of course, because we always begin at t=0=1, the moment just experienced is colored by all those not currently being experienced.
Everything is negative or positive, relative to where we have placed our origin.
We think we can see space, but according to the perception of our brains, we are composing the light relative to previous compositions and relative also anticipated compositions.
This is ignoring the fact that the light being composed is 8 million years old…
similar to Kierkegaard’s intuition that the present is the intersection of eternity and time.
Meaning comes at the cost of time.
