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?
Human nature, as I define it, is the set of cognitive and behavioral patterns that are innate in human beings, regardless of culture and specific upbringing. These are patterns passed down to us by evolution. With humans, though, we seem to be unique in our ability for metacognition – thinking about our thinking and our behaviors. Does that give us the ability to change our innate human nature?
