I do not think available evidence supports the idea that most people with average or better intelligence can or do understand rights. People certainly misuse the term all the time. They are actually philosophical concepts which, in my opinion, most people have neither the patience nor the insight to comprehend.
Well, and they are both carnivores. And mammals. With excellent senses of smell. Who prey on many of the same animals and live in near proximity to one another.
This idea of a different “nature” is really funny. I thought most of y’all here were atheists. Bears are really just an evolutionary skip and a jump a way from wolves, not that different at all. But, then, this is an economics forum, so gross ignorance of biology should, perhaps, be expected.
There is nothing (unless you have some religious conviction otherwise) which essentially seperates us from other animals. I will agree that our reasoning is greater, and even that we are more advanced, but these are matters of degree. That we are somehow different by our very nature is an extraordinary claim, and you need to back it up with evidence. Just saying “look how big our frontal lobes are” does not constitute sufficient evidence.
Many other animals are capable of communication, tool use, affection, fear, pain, malice… I think the real reason for the resistance here is that any good Austrian is faced with the prospect of either becoming a vegan, or rejecting the NAP, should they acknowledge that animals are at all capable of self-ownership. Under such a strain, no wonder they resist the concept so very adamantly.
