The essence of Nihilism; doctrine that does not exist.

“…for we admit that they may have courage (horses and lions, for example); but we do not admit that they have justice, equity, and goodness; for they are not endowed with reason or speech.”

in quibus inesse fortitudinem saepe dicimus, ut in equis, in leonibus, iustitiam, aequitatem, bonitatem non dicimus; sunt enim rationis et orationis expertes

Cicero held that lions had no language, nor the horse. Aristotle was of the view that the horse (a-logo auf Greek) was ennobled by exogenous domestication. For the reason that it participated in the divine, in the rational order according to the human soul. Today, one constantly hears the cliche that one can not deny speech to animals. What does it mean to claim animals can not speak?

Negatively, it seems to mean: humans can not speak! I.e., there is no ratio at the core of the human, which is divine. Ergo, speech is mere “behavior”.

Yes - just dogs barking.

However, dogs have no doctrine of nihilism. So the pig is thoughtless.
