In the discussed scenario, therefore, the emplacement of circumstanced ex-istentialities in nature is found whenever a break affects some efficient causal chain. The last link of this chain phenomenizes as the reaction of an at least partly self-knowing being, a reaction that becomes gnoseologically apprehended but lacks causal efficiency to further its preceding causal series. As empirically found, outer causal efficiency can work out intonative reactions in psychisms, but it cannot cause psychisms to be affected in such a way as to instrumentally transmit the outer effi-ciency. Any causal consequence from this outer efficiency is thus to be a new causal string unpromptedly originated by the causal efficiency of the same self-knowing being that had the gnoseological apprehension, and selected it as a causal antece-dent rather than deselecting it, or else adjusted it contextually to posit it as a causal antecedent. Such events do not happen in the hylozoic hiatus, where all of the causal series continue (i. e., all causal efficiency is transeunt, matter-energy is conserved over effects) but, in exchange, there is no gnoseological apprehension. In other words, by coming to gnoseological apprehension, the causal series that led toward the intonative reaction cannot continue any longer; an unprompted enact-ment of the efficient causality of the same self-knowing reality is now needed to start another causal series, which may enact continuity with or departure from the route of the former causal series.
Always in the examined scenario, and assuming a plausible understanding of causation (not to be discussed here), one might question how privately accessible mental events can cause or be caused by non-privately accessible physical events. The reason is, because efficient causation is the same for both mental and physical events, as well as across them. The mind.brain causally-efficient interaction is not more perplexing than the field generation of variations in local potentials. In estab-lishing, as initial causal link to set in motion some course of regular extramental ef-fects usually called “voluntary behavior,” the local potentials of the field whose car-riers are utilized by minds to launch this causal series, every circunstanced mind does the same as all segregated fields do everywhere but in the microphysical scale when, from an unlocalizable set of determinations, they make themselves bring forth either more, or less, of its force carriers at every spot of volume, thereby changing the spatial distribution of their local potential (which in macroscopic scales may remain stable on average). In setting up sensations the circumstanced mind’s immediate field, on the same efficient causality, generates intonative reactions in the mind.
But no dimensional mirroring of actions with reactions is conserved across the brain-mind interface. Where no minds exist, actions and reactions characterize each another with features from the same set. But in a nature that includes opera-tions originated by minds, intonations are found to result from extramental actions that are depicted with a certain set of features, which actions generate reactions depicted with another set of features. This symmetry breaking is a very fundamental datum of the natural science which attempts to describe a nature where the operations of minds are encoun-tered. We observe four segregated or diversified modalities of causal interaction – also dubbed “basic forces,” being by name the strong nuclear force, the weak nu-clear force, the electromagnetic force, and the gravitational force – in its actions outside us, and a further segregated modality of causal interaction or “basic force,” namely the one which acts as a Newtonian force on biospheric evolution and whose action carriers undergo the speed variations that tune the mind’s time acuity, like-wise from its actions outside of us (e. g. its effects in biological evolution) but moreover from our reactions to it. Such reactions are the mind’s subjective intona-tions, or sensational phenomena.
