<<<<Humans have a soul, given by God. Animals dont, they were created for man. >>
I disagree, I think all animals are ensouled. >>
How can you possible say that either only humans are 'ensouled' or humans and animals are both 'ensouled'?
The 'soul-theory' was created to explain why we Humans are so 'intelligent', because they couldn't imagine that it was a result of some simple evolution.
This theory isn't based on anything but myths and conflicts with experiments. You know for example that if you cut some connections in a Human brain, that that person can suddenly become totally different?
A good example is that of the accident of Phineas Gage, an explosives-expert for the American Railroad compagny. In 1848, his skull was pierced by an iron pin when he was working with some explosives before his assistant had put sand on those explosives.
He did survive this accident, but his personality was changed forever. Before the accident, Gage was a nice and friendly guy, who treated his family very well. After the accident he was asocial, cursed constantly, got angry for no reason and was very unreliable with appointments. He was fired not soon after and he died twelve years later due to an epileptic attack.
This story shows that 'personality' is located in a part of the brain, just like speach, motorical functions, sight, etc.
Experiments with chimpanzee show us that when the nerves between the prefrontal lobes and and the rest of the brains are cut, the personality of those chimpanzee changes dramatically, they suddenly became either very friendly or very agressive. (lobotomy, formerly used to treat mental illness)
