Naturally, I have forgotten all that I wanted to say exactly except for two things. First, I thank you, dearest sister in Christ, for your continuing insights into the great philosophers - in this case, Hume.
And secondly, that causality is a fundamental principle of physics. This is certainly true in Newtonian physics.
It is only when time is understood as geometry (General Relativity, Vafa's f-theory, Wesson's 5D2T etc.) that the arrow of time can be disturbed in theory and thereby, causality.
If time is volumetric, then effect>cause is possible as surely as cause>effect, etc. And in the warping of space/time (General Relativity) it is possible for the space/time continuum to fold onto itself and hence, facilitate faster than light travel as well as time travel.
Obviously a prime objection to all such theories among physicists is precisely that, the principle of causality without which their investigations would be groundless.
The objection presumes that the observer (or investigator physicist) has an objective grasp of reality and/or truth.
I would say "not so" - that on principle an observer "in" space/time cannot know "all that there is" all at once. Even if his sensory perception would allow him, he would nevertheless be a part of his own observation.
Only God the Creator is not part of the Creation. He alone sees every where and every when. Only He knows objective truth. Only He speaks objective truth.
Indeed, He IS Truth. When He says a thing, it is. It is because He said it.
By the word of the LORD were the heavens made; and all the host of them by the breath of his mouth. - Psalms 33:6
To me, the following verse declare that God is not causally constrained or limited in any way by the dimensionality of time:
According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love: - Ephesians 1:4
Oh so true, dearest sister in Christ! Evidently the reason physicists reject the idea of final cause is it "looks like" a "pull" from the future which in Newton's theory of causation cannot happen.
And yet as you say "If time is volumetric, then effect>cause is possible as surely as cause>effect, etc." Newton's formalism, however, is premised on time being linear and irreversible.
Also so very true: "on principle an observer 'in' space/time cannot know 'all that there is' all at once. Even if his sensory perception would allow him, he would nevertheless be a part of his own observation."
Thank you so very much for your outstanding observations! Sorry to hear you lost power.... I'm SO glad it's back on, and you're here! We're supposed to get hit by Irene sometime tomorrow. So I expect we'll lose power at some point, too....
