Now for me, double-aspect is a only in our models and not existing in reality beyond us. — Apustimelogist
I will assume that your philosophical "reality beyond" is something like Plato's Ideality, or Kant's mysterious realm of the ding-an-sich ; not a religious other-world populated with meddling gods & avenging angels. The comments here only skim the surface of my information-based
BothAnd Monism. One holistic uber-reality with dual aspects.
Dualism is a philosophical issue only because our mental models can include referents to
both perceived objects,
and "things" that we know only by
imagination. To wit : Ancient people inferred that there must be
something invisible about humans that explains how they are different from animals (Reason), and how a living body is different from a dead body (Animation). Early labels for that unseen something (e.g. Greek psuche) seemed to equate Life & Mind as dual aspects of a universal Elan Vital.
So, eventually the Soul (Ghost) was imagined as a separate being, temporarily merged with a material body. But, Descartes' dualism focused mainly on the essential difference between a 3-dimensional physical body (
res extensa) and a zero-dimensional metaphysical mind (
res cogitans). And, Kant postulated that there must be a
noumenal "reality" (or Ideality) beyond the scope of our
phenomenal senses. He admitted that we can't actually know anything about that Platonic realm. Yet, he concluded that we can
use reason & imagination to infer some logically necessary properties of such an immaterial sphere of unformed potential.
But, another perspective on the Platonic world of archetypal forms says that it is the True Reality --- a sort of heaven --- and our physical senses can detect only vague hints of what's really real. Even so, faced with a big-bang beginning, we can conjecture that our space-time world is not absolute, but merely a passing shadow (a model) of a more all-encompassing timeless realm of Potential.
It's that extra-sensory speculation, though, that Materialism denies, and for good practical reasons. So, only impractical philosophers concern themselves with things they can't see or touch, but only imagine. Moreover, for Materialists, anything imaginary is immaterial, possibly illusory, and can't be proven to exist in any sensible manner.
So, there are at least
two alternatives to traditional Body/Soul dualism : A> Matter-only monism, or B> Mind-only monism. Yet the latter is literally unrealistic, and the former is essentially mindless. So, I prefer a philosophical model, based on Information, that makes sense, both physically and metaphysically. For example, the
Brain is a biological processor of Information, and the
Mind is merely its operational Function, which is only a name for an abstract input-output process of Living & Thinking. The process is not the thing, and we infer functions only by meta-physical inference, not by physical sensation. Yet,
viewed as a whole system, that mind/matter duality is a singular Person : You.
Is the information stored on a computer metaphysical or physical? :
Great question. All information is metaphysical - necessarily so, in fact. Information exists as differences, and a difference is the one thing you definitely cannot prove exists in physics . . . . The physical structure is the material organisation. . . . . For this reason all information can be considered as sets of co-ordinates, but the actualisation of the information (the manner in which it becomes intelligible) involves the solution of the differences.

Note --- Well-informed people have argued for both sides of the physical/metaphysical question. So, I conclude that
Generic Information must take on both forms. If not physical, computers would not be able to process it. If not metaphysical, humans could not make sense of it. So, the Information of which our world, and our world models, are constructed is Both-And, not Either-Or.
BothAnd is a Monism.
