In recent decades, the idea in modal logic and metaphysics of possible worlds has become a widely used tool in philosophy. But are the hypotheticals discussed using possible worlds even, well, possible? To test this idea, I am going to try to construct an idea of possible worlds by way of mathematical models for making adjustments to the world as understood in both a metaphysically materialist/physicalist sense as well as what assumptions must be present for immaterialist/spiritualist claims to be true.

Semantics and the Phenomenology of Meaning
When someone utters a word that reaches your ear, the sound gets broken down into component waves via Fourier transform which vibrate within cochlear fluid and cause the movement of mechanoreceptor hair cells at the organ of Corti to produce electrochemical signals in the form of neurotransmitter release whereby the movement of the fluid stimulates the filaments of individual cells receptor cells to become open to receive the potassium-rich endolymph, causing the cell to produce an action potential which is transmitted through the spiral ganglion to the auditory portion of the vestibulo-cochlear nerve to the the brain, which signals to the cortex with new information that is then compared to predictions based on prior experience in a Bayesian fashion to produce the phenomenology of the experience of hearing, interpreting, and understanding the word. But where (and how), in all this, does the phenomenology of meaning arise?
A Property Dualism Metaphysics
This is a sort of half-baked theory I was playing around with in my head. Maybe someone else will know where to take it from here?
