The brain may be superior, and superiority may reflect in standing, but Jesus turned that all upside-down :
Neither be ye called masters: for one is your Master, even Christ.
But he that is greatest among you shall be your servant.
And whosoever shall exalt himself shall be abased; and he that shall humble himself shall be exalted.
Matthew 23:10-12
And there was also a strife among them, which of them should be accounted the greatest.
And he said unto them, The kings of the Gentiles exercise lordship over them; and they that exercise authority upon them are called benefactors.
But ye shall not be so: but he that is greatest among you, let him be as the younger; and he that is chief, as he that doth serve.
For whether is greater, he that sitteth at meat, or he that serveth? is not he that sitteth at meat? but I am among you as he that serveth.
Luke 22:24-27
