…but the fact is the same, from weakness and sluggishness we cannot get through to the surface of the air, since if a man could come to the top of it, and get wings and fly up, he could peep over and look, just as fishes here peep up out of the sea and look at what is there, and if his nature allowed him to endure the sight, he could learn and know that this is the true heaven and the true light and the true earth.
Plato, Phaedo, tr. W.H.D Rouse
Having breached the sky and gone to space, we’re no closer to this truth than poor Plato was. The obvious conclusion is that there must be a space above space (just as there is air above water, and space above air); from this vantage we should be able to see the truth, if we don’t have to squint too hard to do so; hopefully this is the final layer to the onion; hopefully the onion is not infinite; hopefully the point at which sky and earth meet does not disappear “at the same rate in which we approach it.”
