The world is conflict because conflict is inherent to life on Earth. Nearly every single biological life form exists only because it eats something else that is alive, and it's possible that all life forms have some consciousness, even plants. Violence is inherent to our existence, and because of that conflict is inescapable.

We don't have an inner animal. We are animals. We are mammals, and more specifically we are hominins and very closely related to other apes. We are one hundred percent animals, unless you accept that we also are spirit, or that consciousness transcends materiality. I appreciate the idea that we are more than our material selves, but I think this individual frames the ideas poorly. The framing is in a very western, anthropocentric perspective that denigrates animal nature. All our biological nature is animal nature. There isn't any other kind of nature that exists, unless, again, you believe that consciousness is the foundational reality of existence and that consciousness creates the experience of materiality, rather than believing the materialistic perspective that Nature creates consciousness. It's one or the other. But if you believe the one, that materiality creates consciousness, then we are one hundred percent animals.

There is nothing wrong with animals. I like them a lot, especially many of the non-human kind. We make ourselves insane more than they do. I find them more peaceful than humans most of the time.
