Aetiology of the cosmic safehold - here I look into the aetiology of the cosmic safehold, surveying the possible causes, reasons and other explanantia for its presence, seeking to explain it : re `cosmic safehold` see `^*Allan.+2026.+The presence throughout the cosmos` @ sources.brec - to begin with, the possibilities are obscure, but one thing stands out as obvious: the safehold is physically bound up (entangled) with the larger cosmos - now, already cosmology has looked into the aetiology of another such entangled phenomenon, the apparent fine tuning of the physical laws, constants and conditions of the cosmos for the support of life, and sought to explain *it* ∴ I begin by adapting the explanantia of that pre-existing aetiology by this procedure: for( each proposed explanans ⁠E⁠ of the apparent fine tuning ⁠F⁠ ) ⁃ divorce ⁠E⁠ from the explanandum of ⁠F⁠ : note : that is all for fine tuning itself, it will not figure as a premise of the present aetiology ⁃ apply ⁠E⁠ instead, mutatis mutandis, as an explanans of the cosmic safehold - the resulting set of adapted explanantia I then take to serve as the set of known, possible explanantia for the safehold - these I order by Jason Waller’s typologic scheme, as follows table, Typology of known, possible explanantia for the cosmic safehold ┈ explain- truth mode name of explanans able of explanans yes necessary physical necessity supernatural design ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ contingent natural cosmogonal selection constrained multiverse ensemble mundane design ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ no null, brute fact : re `J.+W.+scheme` see `^*Waller.+2020.+Cosmological fine-tuning arguments` @ sources.brec : ‘The division goes like this. Either the [phenomenon] has an explanation… or it does not. If it does not, then the [phenomenon] is a brute fact. … [Otherwise] there is an explanation… the explanation is either a necessary truth or it is not. … if it is not… then it must be [a] contingent [truth]. This is the basic reasoning behind the classification scheme.’ §4, pp. 201-2 physical necessity • reality’s structure is explainable by a (yet unknown) theory of fundamental physics ⁠T⁠ • necessarily ⁠T⁠ is true • ⁠T⁠ implies the safehold : see also `^*Friederich.+2026.+Fine-tuning` @ sources.brec : ‘a so-called *theory of everything* according to which… the laws and constants of physics… turn out to be dictated completely by fundamental general principles.’ §2.3 : contra `^*Ratzsch.+and.+Koperski.+2023` @ sources.brec : that an explanans of this form gives ‘a promissory note rather than an explanation’ §4.1.2.1 supernatural design • necessarily there exists a supernatural actor (God) who made and rules the universe • God made the safehold • God had reason to make the safehold natural cosmogonal selection • alternative paths of cosmogony are possible • any actual path is the cull of a (yet unknown) natural process of cosmogonal path selection ⁠P⁠ • ⁠P⁠ cosmogony tends to produce a safehold • ⁠P⁠ cosmogony produced the safehold : see also `^*Friederich.+2026.+Fine-tuning` @ sources.brec : ‘a *dynamical* account of the generation of life-friendly conditions, in analogy to the… “dynamical” evolutionary account of biological fine-tuning’ §2.3 constrained multiverse ensemble • multiple cosmoi exist or have existed • some cosmoi have conditions that support the development of life (habitable cosmoi) • some cosmoi have conditions that yield a safehold (safeholding cosmoi) • the conditions of habitability and the conditions of safeholding are bound together by a (yet unknown) constraint of exobiology and cosmogony ⁠C⁠ such that habitable cosmoi (like ours) tend also to be safeholding cosmoi • habitability and ⁠C⁠ conditioned our cosmos to be safeholding mundane design • multiple cosmoi exist or have existed • some cosmoi have conditions that support the development of life (habitable cosmoi) • some cosmoi have conditions that support cosmogenesis (cosmogenetic cosmoi) • some habital, cosmogenetic cosmoi evolve inhabitants who come to engage in artificial cosmogenesis (cosmocrafters) • some cosmocrafters succeed in making cosmoi (crafted cosmoi) : note : lineal generation 1 or later, yielding a line length ≥ 1 crafted cosmos • some crafted cosmoi evolve cosmocrafters who succeed in furthering their cosmic lines : note : lineal generation 2 or later, yielding a line length ≥ 2 crafted cosmoi • cosmocrafters have reason to engage in making and furthering lines of crafted cosmoi (lineal cosmocrafting) • the incorporation of a cosmic safehold serves the purpose of lineal cosmocrafting • ancestral cosmocrafters made our cosmos for the purpose of lineal cosmocrafting and incorporated a safehold to serve that purpose : privately see `^^authorial priority$`i @ ._/text.notes.brec brute fact \ the null explanans • a contingent state of affairs for which no explanation exists to be discovered (a brute fact) is possible : re `(a contingent state of affairs .+ \(a brute fact\))`s see `^*Waller.+2020.+Cosmological fine-tuning arguments` @ sources.brec : ‘A brute fact is a contingent state of affairs for which no explanation exists… not a contingent state of affairs that we are just not able to explain yet (or that we will never be able to explain), but a [contingent] state of affairs for which no explanation exists to be discovered.’ §1.3.1, pp. 24-5 • the safehold is a brute fact
