It is an exercise in human power to admit that we are just simple automated machines, that we don't think, that we don't have reasoning, that we only act by instinct, because then you can use us at your pleasure. So, the fact that you do not admit the existence of the mind or the soul of animals is the same mechanism of exercising power used in relation to slaves, a little more than 100 years ago, isn't it? How did the Clergy and other institutions live with that? Admitting that the slaves had no soul, it was a strategy for exercising power. And abuse of power is what you too continue to do, not only with our species, but with all animals!
