Sentience

[Helm]

Aye. Another defining feature of humanity is its ability to create and partake in culture, technology, social structure, values etc. Though rooted in our higher intelligence and other helpful qualities, it is what we do with our intelligence that makes us "human"

That's a bit romantic. Not to say I wouldn't like to agree with it, but I don't see how adding such uses (which are products of said intelligence, as we agree) to a definition we're hoping to keep compact helps things in any way. As a broader (moral) commentary to said definition, of course I agree. You do realise what you just posted is a moral claim, right? Just checking because last time we discussed any of this your understanding of morality was by my standards a bit narrow.

In fact, thinking about this a bit more, I'm seeing how this, if approached in any other way than as a moral claim it can be dangerously misleading. There is a very strong "I believe it should be so" in your statement :it is what we do with our intelligence that makes us "human".
