The Christian view is that men were created to be in a certain relationship to God (if we are in that relation to Him, the right relation to one another will follow inevitably).
It is, of course, quite true that God will not love you any less, or have less use for you, if you happen to have been born with a very second-rate brain.
We only learn to behave ourselves in the presence of God.
When Catholicism goes bad it becomes the religion of amulets and holy places and priestcraft: Protestantism, in its corresponding decay, becomes a vague mist of ethical platitudes
The theory that thought is merely a movement in the brain is, in my opinion, nonsense; for if so, that theory itself would be merely a movement, an event among atoms, which may have speed and direction but of which it would be meaningless to use the words 'true' or 'false'.
