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?
The colloquial way of defining what it means for a statement to be true is that it corresponds to reality: if I say “it is raining” and it’s also the case that it’s raining, then what I said is true; if I say “it is raining” and it’s not the case that it’s raining, then what I said is false. This is an extensional truth condition – the extension of the proposition must be the case in reality for the statement to be true. But is this really how truth works? In what follows, I am riffing on some ideas floating around in my head, so feel free to point out any problems so as to help me clarify my thoughts.
