Language / Hacking: (goes back to the Leakey family (?)) Thesis: language was invented out of boredom, to tell each other jokes around the campfire.
Thesis: the first word that was needed was something to express: "real" e.g. "No, not this, but this here is real": (To the rest of you could point). - Even before the name (for absent objects) one needed logical constants. Instead of "Me Tarzan, you Jane" - "This real" Once a way of representing is found (e.g. pointing) followed by a second-order term in tow.
VsHacking: pointless to set up a theory that can not be confirmed.
