sophont

• (US) IPA^(key): /ˈsoʊfɑnt/

sophont (plural sophonts)

1. (chiefly science fiction) An intelligent being; a being with a base reasoning capacity roughly equivalent to or greater than that of a human being. The word does not apply to machines unless they have true artificial intelligence, rather than mere processing capacity.
   • 1966, Anderson, Poul, Trouble Twisters:

     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.

   • 1980, David Brin, Sundiver, page 50:

     I'm honored to meet a sophont of the Soro line in person!

   • 1992, Vernor Vinge, A Fire Upon the Deep, Tor Books, page 406:

     Evil, they argued, could only have meaning on smaller scales, in the hurt that one sophont does to another.

   • 1997, Spider Robinson, Lifehouse, Baen Books, page 2:

     Only one sophont appeared to be involved—and not a sophisticated one.
