It is sometimes said: animals don't speak, because they
lack
haven't
the ˇnecessary intellectual capacities. And this means: ‘they don't think, therefore they don't speak’. But the fact is that they just don't speak. Or
rather
t
: they don't use language. (If we disregard except the most primitive forms of language.)
Giving orders
Commanding
, askingˇ questions,
describing
recounting
, prattling, belong to our natural history just as walking, eating, drinking, playing do. (It makes no difference here whether the speaking is ˇdone with the mouth or ˇdone with the hand.)
