Nietzsche human v. animal

Within the first paragraph of On Truth and Lying in the Extra-Moral Sense, Nietzsche establishes that he considers humans to be "clever animals". Most people reading On Truth and Lying will view human v. animal as a binary; two things that are opposites. One side is known for its intelligence while the other side is characterized by its general lack of. Humans consider themselves to be in a different better league than animals. Nietzsche, however, does not believe this. He states, "After nature had taken a few breaths, the star froze over and the clever animal had to die." He believes that humans are just as insignificant as other animals. Throughout On Truth and Lying, Nietzsche uses phrases normally used to describe animals to describe humans. He states humans "are denied the horns and sharp teeth of beasts of prey", so they use their intellect. Nietzsche implies that humans are "beasts of prey" that use intellect instead of "horns and sharp teeth" to conquer. He also says, "man, out of necessity and boredom, wants to live socially in a herd." Nietzsche repeats this binary in order to drive home the point that in nature humans and animals and the same and not binary opposites. He needs us to believe this idea in order to prove that humans do live in a cathedral built of lies. He writes, "Everything that sets man off from the animal depends upon this capacity to dilute the concrete metaphors into schema; for in the realm of such schemata, something is possible...a new world of laws, privileges, subordination, boundary determinations, which now stands opposite the other, concrete world of primary impressions..." According to Nietzsche, we perceive human v. animal to be a binary because we lie to ourselves.
