Your "zombie", in the philosophical usage of the term, is putatively a being that is exactly like you in every respect—identical behavior, identical speech, identical brain; every atom and quark in exactly the same position, moving according to the same causal laws of motion—except that your zombie is not conscious.

It is furthermore claimed that if zombies are "possible" (a term over which battles are still being fought), then, purely from our knowledge of this "possibility", we can deduce a priori that consciousness is extra-physical, in a sense to be described below; the standard term for this position is "epiphenomenalism".

(For those unfamiliar with zombies, I emphasize that this is not a strawman. See, for example, the SEP entry on Zombies. The "possibility" of zombies is accepted by a substantial fraction, possibly a majority, of academic philosophers of consciousness.)

I once read somewhere, "You are not the one who speaks your thoughts—you are the one who hears your thoughts". In Hebrew, the word for the highest soul, that which God breathed into Adam, is N'Shama—"the hearer".

If you conceive of "consciousness" as a purely passive listening, then the notion of a zombie initially seems easy to imagine. It's someone who lacks the N'Shama, the hearer.

(Warning: Long post ahead. Very long 6,600-word post involving David Chalmers ahead. This may be taken as my demonstrative counterexample to Richard Chappell's Arguing with Eliezer Part II, in which Richard accuses me of not engaging with the complex arguments of real philosophers. Edit December 2019: There now exists a shorter edited version of this post here)

When you open a refrigerator and find that the orange juice is gone, you think "Darn, I'm out of orange juice." The sound of these words is probably represented in your auditory cortex, as though you'd heard someone else say it. (Why do I think this? Because native Chinese speakers can remember longer digit sequences than English-speakers. Chinese digits are all single syllables, and so Chinese speakers can remember around ten digits, versus the famous "seven plus or minus two" for English speakers. There appears to be a loop of repeating sounds back to yourself, a size limit on working memory in the auditory cortex, which is genuinely phoneme-based.)
