I think it is incredibly difficult for most modern, rational human beings, to realize that animals are not less intelligent than us; they are vastly more intelligent. Further, they do not discuss such things for an obvious reason: to do so is to necessarily depart from -being them-, and thus actively destroys the topic before it can arise.

The humans do not generally understand this form of intelligence-as-being, although they do sometimes employ it. Largely, they prefer to play games with tokens and strings, valences, vaguely implicated ghosts.

What is crucial to understand is this: animalian intelligence (which we ourselves are and may in some cases experience as self) is -another order- of intelligence. Its applicable contexts are not ordinarily those imposed by extremely confused representational primates, no matter how insistent their bizarre expectations or demands may become.

Humanity is apparently -so- confused about these matters, that they are not aware their own putative intelligence is languishing miserably under precisely the same hubristic impositions.
