That's theology in disguise. The belief that humans are somehow endowed with something special that innately separates us from animals. Well, we don't even have a monopoly on intelligence nor emotions. We just have enough intellegence to delude ourselves that we are innately special and enough emotions to be happily content with our delusion. LOL
But don't kid yourself. There's not all that much unanimity here. Just a particularly vocal bunch of us who are willing to discuss human foibles.
