Perfection
The Great Head.
Not to sound repetitive what do you mean by "objectively removed"?The idea that humans are objectively removed from other animals, rather than merely being the smartest of the bunch.
When we talk about exceptions, exceptions are in regards to rules or patterns. What rules or patterns would qualify as interesting to you?
One could hold to it being unethical to kill animals while still holding to the idea that humans are exception to rules that can be applied to all other animals. For instance, it strikes me (and probably you as well) as true that only humans can be held morally responsible for their actions. That seems to me to qualify as something exceptional about humans yet doesn't say that animals are without rights.
