X existence. What 'tis it?
Yes, that is the question. Fun to contemplate it.
Traditional theism would say it is supernatural existence, or that which is unexplainable in terms of natural, materialistic causes. Positivists, of course, reject this. If it ain’t empirically verifiable, explainable in terms of cause and effect in the natural order, it don’t exist. Just because we can’t explain something now, doesn’t mean that we won’t be able to someday. But traditional theists, I think, would stubbornly insist that there a supernatural order (it X-exists) and that is unknowable through the natural order in principle. (How convenient, the positivists retort).
Well, fortunately I do not subscribe to the concept that if it is not empirically verifyable, it is nonsense. The laws of logic, for example cannot be empirically verified and still we accept them as axiomatically true. So, that is one hurdle we both took without falling on our face.
Process metaphysicians like Whitehead and Hartshorne argue that there must be X-existence as a matter of metaphysical truth. These guys see X existence when the whole of reality is contemplated. A whole is always more than the mere sum of its parts or fragments. So X existence is that which “ties it all together” or makes it one.
I am not sure how is this different from C-existence.
Process guys would say that there must be something novel always added to reality which is indeterminate or free. i.e. not explainable by a cause. If reality is a process, a succession of events (“one dang thang after anudder”), the succeeding event must always be more than the sum of its causes. For it weren’t, then no change is possible and nothing could happen.
That is fine, but the causative agent is always another physical entity.
Here is the problem as I see it. The X-existence is different from C-existence. A concept is an “inert” entity, it cannot “do” anything. (We as, phisical beings, can act on a concept, of course, but that is not the same.)
P-existence we know about. The concept of verification is applicable here, we can say if it cannot be verified, it is not worthy of consideration. That is not a problem, since X-existence is not physical either.
Now, X-existence. There are two possibilities here:
One, that X-existence is completely separate from P-existence, there can be no interaction between the two. Objects that are P-existent cannot act on objects which are X-existent and conversely, objects which are X-existent cannot act on objects which are P-existent. This is a simple case. If there cannot be interactions between the two realms, there is nothing to contemplate. Whether there is any X-existence or not, is irrelevant.
Two, however is much more problematic. We assume that there can be interaction between the two realms, either one way or two-way. Traditional theism assumes a one way action from X to P-existence. For completeness sake we really ought to contemplate all possibilities, but fortunately it is not necessary.
Whether the inteaction is one-way or two-way, the concept of interaction presumes an
interface between the two realms. The interface
must belong to both realms, unless we want to postulate some unknowable “magical” form of interaction - and I would not like to do that - since “magic” cannot be dicussed in a rational manner.
So, here is the problem: if the interface belongs to both realms, then there is an object (the interface) which is both P-existent and X-existent. (This does not preclude that there are objects which are only X-existent and as such not subject to empirical verification.)
Mind you, this does not bring us any closer to understanding the “essense” of X-existence. The properties of X-existence are still total unknowns. How to gain information (knowledge) about X-existence is still up in the air.
But my question presents a practical problem. The interface between the two types of existence is partially physical. It is subject to empirical verification. How can that be accomplished, at least in principle?
What say you?
