Metaphysics is a display of the creator’s mind: his aspirations, fears, objectives; his relationship with existence.
The Platonic Cave is a metaphor for the human skull. The inner spirit of the creator’s mind casting shadows upon the inner wall of his skull. Only there does Plato’s Ideal live, as a thought, an abstraction.
Like in art we witness the artist’s objectives and perspectives displayed in his art.
Has he made himself a translucent lens, reflecting through his creation the a priori interpretations of his mind, unaffected by personal factors, or is his artistry reflective of a more opaque spirit, mixing into his creation his private reactions towards the subject matter?
A range of possibilities is available, beginning from realism and proceeding towards the extreme, abstract art, where the artist has abandoned reality and clearly displays his mathematical corrections, or conceals himself in suggestive colours and forms, obscuring his feelings, hiding in vagueness.

We witness a similar process in a philosopher’s metaphysics.
His relationship to physis – the automatic interpretations of experienced existence – finds expression through his metaphysical musings.
In Schopenhauer we see a Germanic will, desiring to stand outside existence – unaffected, undisturbed, objectively indifferent – willing a life he appreciates as a necessary precondition of this willing; an egotistical desire to prolong himself through his work – the abstractions of his writings. In eastern spirituality he finds this ‘standing outside’ existential positioning. He lives despite his surroundings, detached and unaffected by those around him – more of a desire than an accomplishment since he was extremely affected by others and sought relief in isolation.
Nietzsche’s metaphysics, though not unique, express a sense of insecurity. He does not only want to continue living through his willful abstractions, like Schopenhauer, but he wants to control his life; seize it and liberate it… because it is un-free. His polemics against Christianity’s slavishness expresses this animosity towards his own enslaved spirit. He feels powerless, and so he seeks power; he resents the fact that he is enslaved, by his own fate, and powerless to break free, hoping that a future man – an overman – will succeed where he has failed, and that he, having predicted him, will be liberated through him.
In Kant we see a mind reduced to a vague ‘thing’ seeking in itself salvation from existence – a distinction. Unable to find what he is looking for he is content to claim to be a ‘thing’ internally striving to find completion.
In Spinoza we see the Jewish spirit projecting itself into everything. God’s omnipresence through nature. A Messianic expansion of spirit that has been affected by Christianity’s universality. He is in everything because everything is his interpretation; a subjective creation of his mind.
The choice of words is revelatory. A choice that expresses judgement based on need/desire; a choice exposing intent.

The relationship of physis with metaphysis is the relationship of body to mind - the tangible and the intangible; represented and representation; real/ideal.

Mind strives to claim dominance over physis, either through knowledge and understanding - wisdom - or through linguistic contrivances attempting to control other minds, and through this control gain power over their physis, their physical presence - parasitism.

Overcoming Abrahamism - and all its offshoots, e.g. Marxism, Postmodernism - begins with the overcoming of its semiotic anti-physis metaphysics.

Essentially, the conscious, lucid mind, wants to regain ‘control’ over the acting body, attempting to govern it and in so doing, govern Nature-herself.

Mind-Body Duality, Dualism.

Because of the ‘lag’, the delay, between lucid information processing (sensory experience, perception), most humans interpret the mind/brain as ‘detached’ from reality, separated. This is ultimately the source of their denial of Free-Will.

With no power in physis the modern seeks power in metaphysis.
The announcement of the ‘death of god’ - of Abraham - they lost their power via association and are now desperate for a substitute.

A thorough analysis of the relationship between physis and metaphysis would have to begin with the evolved configuration of the organism, Homo sapient, and its two sources of data…

Just the anatomy alone indicates a duality.
The body is draped around the skeleton, exposed to existence - separated from the world beyond by a thin, porous membrane, or skin - the largest rogan of the human organism; while the brain - from whence the mind emerges - is encased by the skeleton - skull - being sheltered and constantly fed energies.
The body experiences existence as attrition - need/suffering - and draining - lack - a constant struggle - experienced as thirst, hunger, fatigue, pain - whilst the brain experiences only excess requiring constant stimulation to be expunged.
From this I conclude the Apollonian/Dionysian was synthesized.

The body is entirely engaged with the world, a manifestation of causality - including the brain - whist the mind can contradict causality, in theory, in its creations (abstractions), experiencing no restrictions to how it can recombined the data flowing into the brain…or even invert them.
The body’s memories are subconsciously accessible - DNA; the brain has its own source of accumulating memories it collects, processes (interprets) and stores as experience.

This is the real source of the body/mind dichotomy.

From this we can explore the dichotomy of physis/metaphysis…when the mind is assumed to be the ‘real’ making the body - the physical, tangible word - illusory.

Mind is also what Abrahamics refer to - unbeknownst to them - when they speak of a “soul” or of “spirits”.
Mind projecting itself into everything.
Mind assumed to be absolute = immutable, indivisible, eternal…
Mind disconnected from the brain; the body.
mind as creator, since it can create what does not exist, e.g., unicorns, satyrs, etc…or create concepts that are contradictory, like ‘frozen fire’, ‘square circle’…maintaining it as an obscure concept, an idea; an abstraction that cannot exist anywhere but in the mind.
Obscurity is how mind deals with its own self-constradictions; it is how it ‘harmonizes’ and combines what is in contradiction and can never be combined; concepts existing only linguistically…as neural clusters.
Their actual synthesis are these neural clusters that can be simultaneously triggered to produce two incompatible concepts, as if they were one.

Mind knows of no natural limits…in theory. It can travel across space/time, at will, fabricating a presence beyond existence itself.
This creates the contradiction of a multiplicity encompassed by a singularity - a universe; the contradiction of a beginning and an end; the contradiction of an immutable, indivisible thing underlying the mutable, dynamic, multiplicity of experienced existence.

The skull is the Platonic cave, and what is within it is of the mind - shadows on its walls, imagining an “outside” world as an ideal world whose shadow we experience as the real - a nihilistic inversion.

The mind’s ability to invert everything experienced is what is used to construct its noetic defences; its representational, semiotic walls, to protect the ego = lucid part of an organism; a part of the mind awakening to itself.

Metaphysis must align with physis, not physis with metaphysis.

Nihilism inverts their relationship, and uses language to alienate brain from body, or mind from tangible, experienced reality, taking advantage of human existential anxieties desiring an escape from nature uncertainties and indifference; individuals that are dissatisfied with their inheritance, with nature’s injustices, looking for a solution, an escape.
Plenty of them around.
“Spiteful Mutants,” Dutton called them.
I call them Desperate Degenerates.

Metaphysics is the opposite side of empiricism metaphysics is a German doctrine while empiricism is British doctrine constructed by an English philosopher David Hume

For modern society it is better to rely on empiricist ideologies rather than metaphysics because of the rapid changes bought about by technology and the Sciences such as robotics

However sometimes it cannot be controlled that the human mind construe on metaphysics if the subject requires mental judgement therefore struggling for an absolution

Yes…and if metaphysics is allowed to disconnect from the anchoring of physis, it becomes nihilistic or absurd.
Metaphysics must remain anchored to physics.
When it becomes disconnected it is no longer dealing with reality, but with psychology.

So, these “esoteric” poetic word-basd metaphysic you see around the internet forums is all about human psychology…or how man reacts, relates, to physis, nature.
