But you can't measure it objectively. You can't tell me that other people have consciousness, you just assume it is true because they seem to be like you. You have no mechanism for determining the limits of your assumption and indeed past societies have drawn the line in even narrower constraints than "human".
> you just assume it is true because they seem to be like you
A minor, but important point. I don't assume it's true. I just think it is more likely than not.
I suppose that the philosopher I'm talking about could say the same of their theory. And I guess that's OK, if all they're claiming is that this is something that seems likely. My only response to that would be that his induction is prima facie questionable to me.
