No, not Christian faith. In fact, for Christians, quite the opposite is true: you must think deeply and carefully as a disciple of Christ.
"God has room for people with very little sense, but He wants every one to use what sense they have. The proper motto is not 'Be good, sweet maid, and let who can, be clever,' but 'Be good, sweet maid, and don't forget that this involves being as clever as you can.' God is no fonder of intellectual slackers than of any other slackers. If you are thinking of becoming a Christian, I warn you, you are embarking on something which is going to take the whole of you, brains and all… One reason why it needs no special education to be a Christian is that Christianity is an education itself."
