I agree. Our ears are part of the chain, but that's it! Imagine relying on your ears rather than your ears and your brain. What good are a pair of detached ears?Referring to ears instead of hearing is not a good way to start.
I know what is meant by the phrase "trust our ears", but it suggests that the process of hearing is detached from the complexity of what is going on in the brain.
Apologies for the mini-rant.
