Is it normal that i think animals and humans are the same nature ?
I don't believe in souls, our minds are just our brains for me, there is not a thing like a immaterial true-self who is just incarnated in a body, we are bodies (I'm an atheist with a materialistic conception of the Universe, in the philosophical meaning of the word) but I don't see a true seperation between humans and animals : I mean, not only humans seems to be self-conscious and sensible.
It's more a spectrum : ok humans are the most intelligent beings on Earth, but they are animals too and if humans are special and human (and not animal) because they are sensibles and intelligents, dolphins are 90% special and human, a cow 40%, ect....
And in this case it wouldn't means a mentally disabled human is not human or is human ONLY because he had the potential of being intelligent thus "truly" human ?
And if for some reasons I belivied in souls (And I don't see nothing in the world that incitate there is other things than the material world, quite the opposite but it's only my experience) I don't see why humans would have souls and not the animals ? it's absurd to think humans are special and even the animals who are only very slightly less intelligent are souless biological robots.
And a god who creates souless but still sensible beings is just cruel : what is the meaning of the existence of a animal who is deadborn and don't have any afterlife when a dead-born human would get a ticket for the Heavens ? In the reality, both don't exist anymore and it's why our world is amoral and without any god but a world where humans have souls and animals don't would be a immoral world created by a hypocrit, evil and mad god.
