Word for intelligence-kind (akin to humankind, but not homocentric) [duplicate]

Solution 1:

Conceivably you're looking for the word sentience here. So in noun form, sentient beings, sentient life forms or rarely sentients.

The only pitfall is that the definition of sentience its self is much disputed, so it's up to you to then defend your definition of what would qualify. I expect this would be a related problem to your statement no matter what term you use though, so you might as well join the fray with this one.

For reference, here's the wikipedia entry on sentience. There's actually a mention in there of how the term differs from "sapience" which implies a higher degree of thought, reason and learning than sentience, and from which we get "homo sapiens". I suspect from your ask though, that anything that is or appears to be self aware, including animals, should be included in your statement.

Solution 2:

Sophont is a specialized term used primarily in science fiction, as evidenced by the SF Citations for OED database:

Definition: an intelligent being, including humans as well as intelligent aliens.

1966 P. Anderson Trouble Twisters (1969) 57 Likewise with the psychology of intelligent species. Most sophonts indeed possess basic instincts which diverge more or less from man's. With those of radically alien motivations we have little contact.
