The Semantic Apocalypse (2008)

But we have no definition of consciousness and no way of quantifying differences between animals and us (ignoring the fact that we are animals).

> What if consciousness is illusory?

since we don't know what it is nor can measure it (other than in degrees of unconsciousness, which I guess isn't what is meant here), how can we say that is is an illusion, and if so, compared to a non-illusory what?

Finally, who cares? I don't and I guess many people would these days shrug and say, descartes-like "I am what I am" and carry on. It's like religious people saying their morality comes from the bible and the threat of hell, but as secularity emerged over the centuries, the non-religious still behaved pretty much the same morally (I use this as an example of fundamentals turning out to be less important than expected, I don't want to start a religious discussion here)
