I can pass on paraphrases of some comments made by Jacob Bronowski in discussing animal and human communication: animals communicate in words, humans communicate in sentences; and, it isn’t that animals don’t have dialogue, what they don’t have is monologue.
It’s true. Humans have “monologue”. Like, oh, wow, maaaan. That monologue, as far as I can tell, grades imperceptibly off into whatever it is that’s going on when a chimp masturbates. All that monologue, plus a shiny coin…. You know the drill. Unless, of course, you can bend a spoon with it. If all you can do is bend your dick with it, you’re nothing special.
