  Ed, you wrote in #48
I think that the future is an existent, but only in the same sense that a math formula, an architect's building plan, or a unicorn is an existent  it is something conceivable to a human mind.
Just like math formulas, construction plans, and funnylooking horses, we can "see" the future not as we look out to reality (because the future is nowhere to be found), but as we look inward and perform mental functions. We can, with certainty, predict things about the future  just like we can, with certainty, predict the outcome of a math equation  but that doesn't give foreseeable math outcomes or foreseeable futures any special existence (existence entirely independent of a mind).
Do you think that all relations are abstract? Do you think that all relations require consciousness in order for the relations to hold? (Sorry if youve addressed this before and Im not remembering.) Leibniz said Yes, and in a different way so did Kant.
I have held for a long time that the membership relation of concepts and sets is only an abstract relation, not a concrete relation. But I hold that there are also relations that are concrete. There are concrete relations that are perceived and concrete relations that are discerned by abstract thought. Perceived relations would include some relations of proximity, containment, and similarity. Some other similarities, such as that between a water circuit and an electrical circuit, are accessible only by abstraction. (Further, 2nd paragraph, 5th paragraph, and Note 37.)
The fact that the temporal relation that is the future must be known through abstraction (except for the sense of the futurefront of experience), does not mean that the relation itself is not a concrete one existing independently of consciousness.
Temporal successions and the ranks of temporal durations exist independently of our having devised measurement instruments (with ratio scales) for them.
