Anything exists non-vacuously as in Extension (having parts, each of which again is extended) and in Change (extended existents impacting some other extended existents). Anything without these two characteristics cannot exist. THESE ARE THE TWO, EXHAUSTIVE, IMPLICATIONS OF "TO BE" AND "EXISTENTS".
If not in Change, how can something exist in Extension (= in the state of Extension) alone? And if not in Extension, how can something exist in the state of Change alone? These are impossible. ((The traditional interpretations of Parmenides and Heraclitus as emphasizing merely one of these is unacceptable.)) Hence, Extension-Change are two fundamentally physical-ontological Categories of all existence.
But Extension-Change-wise existence is what we understand as Causality: extended existents and their parts exert impacts on other extended existents. Every part of existents does it. This is not the meaning of Change alone, but in Extension-Change! That is, if everything exists, everything is in Causation. This is the principle of Universal Causality...! All counterfactual imaginations need not yield really existent worlds of this kind.
Even the allegedly “non-causal” quantum-mechanical constituent processes are mathematically and statistically circumscribed, measuremental, concepts from the results of experiments upon Extended-Changing existents; and ipso facto the realities behind these statistical measurements are in Extension-Change if they are physically existent.
Space is the measured shape of Extension; time is that of Change. Therefore, space and time are merely epistemic categories. How then can statistical causality be causality at all? Bayesians should now re-interpret their results in terms of Universal Causality, as mere measuremental extent of our determination of the exact causes of some events.
No part of an existent is non-extended and non-changing. One unit of cause and effect may be called a process. Every existent and its parts are fully processual -- in the sense that every part of it is further constituted by sub-processes. None of these sub-processes is infinitesimal. Each is near-infinitesimal in Extension and Change.
Thus, Extension and Change are the very exhaustive meanings of To Be, and hence I call them the highest Categories of metaphysics, physical ontology, the sciences, etc. Science and philosophy must obey these two Categories if they deal with existent processes, and not merely of imaginary counterfactual worlds.
In short, everything existent is causal. Hence, Universal Causality as the highest pre-scientific Law, second only to Existence / To Be. To Be is not a law; it is the very reason for existence of anything...!
Natural laws are merely derivative from Universal Causality. If any natural law disobeys Universal Causality, it is not a scientific law. Since Extension-Change-wise existence is the same as Universal Causality, scientific laws are derived from Universal Causality, and not vice versa.
Today sciences attempt to derive causality from the various scientific laws! This is merely because millennia long we have been getting fooled about such a fundamental meaning of Causality. We were told that causality can be proved only empirically. The folly here has been that what is specific is universalized: The Fallacy of Conceptual / Theoretical Wholes and Parts. Search for the causes of a few events has been misinterpreted as capable of defining the search for the causal nature or non-causal nature of all...! IS THIS NOT ENOUGH PROOF FOR THE INFANCY IN WHICH THE FOUNDATIONS OF SCIENTIFIC AND PHILOSOPHICAL PRINCIPLES FIND THEMSELVES IN?
The relevance of metaphysics / physical ontology for the sciences is clear from the above. Lack of such a metaphysical foundation has marred the effectivity of the sciences and of course of philosophy as such. RECOLLECT THE ERA IN THE TWENTIETH CENTURY WHEN CAUSALITY WAS CONVERTED TO CAUSAL EXPLANATIONS.........
Existents have some Activity and Stability. This is a fully physical fact. These two categories may be shown to be subservient to Extension-Change. Pure vacuum (non-existence) is the absence of Activity and Stability. Thus, entities are irreducibly active-stable processes in Extension-Change. Physical entities / processes possess finite Activity and Stability. Activity and Stability together belong to Extension; and Activity and Stability together belong to Change too.
That is, Stability is not merely about space; and Activity is not merely about time. But the traditions (in both the sciences and philosophy) still seem to hold so. We consider Activity and Stability as sub-categories, because they are based on Extension-Change, which together add up to Universal Causality; and each unit of cause and effect is a process.
These are not Categories belonging to merely imaginary counterfactual situations. The Categories of Extension-Change and their sub-formulations are all about existents. There can be counterfactuals that signify cases that appertain existent processes. But separating these cases from useless logical talk is near to impossible in linguistic-analytically and denotatively active definitions of reference in logic, philosophy, philosophy of science, and the sciences. THE FAD NATURE OF THE PHILOSOPHIES OF FREGE, WITTGENSTEIN, THE VIENNA CIRCLE, AND THEIR FOLLOWERS TODAY FOLLOWS FROM THIS.
Today physics and the various sciences do something like this in that they indulge in particularistically defined terms and procedures, blindly thinking that these can directly denotatively represent the physical processes under inquiry.
Concerning mathematical applications too this is the majority attitude among scientists. Hence, without a very general physical ontology of Categories that are applicable to all existent processes, all sciences are in gross handicap. THIS IS A GENERAL INDICATION FOR THE DIRECTION OF QUALITATIVE GROWTH IN THE SCIENCES AND PHILOSOPHY.
The best examples are mathematical continuity and discreteness being attributed to physical processes IN THE MATHEMATICALLY INSTRUMENTALIZED SCIENCES. Mathematical continuity and discreteness are to be anathema in the sciences. Existent processes are continuous and discrete only in their Causality.
This is nothing but Extension-Change-wise discrete causal continuity. At any time, causality is present in anything, hence there is causal continuity. But this is different from mathematical continuity and discreteness.
