Modern physics’ relativities, especially description relativity, which is slowly accepted through string-theory dualities for example, enlighten the mathematics versus physics dichotomy. Description relativistic metaphysics developed from enforcing consistency between dual perspectives, especially between more physicalist and purely mathematical description (logical realm) and for closely related conceptual dualisms (objective/subjective etc.). Applied practically, for example enforcing consistency between the “timelessness” of the mathematical realm and “flow of time” in causal physics, Einstein-Everett relativity falls out as a priori, metaphysically necessary, as well as scientifically exact, namely with the correct standard quantum correlation. The theory of everything (ToE), whatever mathematical physics it is, is a description. It must effectively describe also itself (everything!). The ToE thus obtains from describing it directly as a description with particular features simply due to being the ToE. Description relative metaphysics becomes or is nothing but the ToE. Obtaining the core of relativistic quantum theory with hints toward quantum-gravity unification and without empirical input confirms that description relative metaphysics obtains the desired ToE. This amazing (though expected) result justifies treating mathematics and physics as self-evidently consistent analytic logic of language somewhat like attempted by Gottlob Frege (1848-1925).
