Few look deep.

First, Aristotle observes that "uncommon devotion" to religion, rather than just being religious, is a characteristic of tyrants. Such a ruler would have to make a great show of religiosity, just to make sure everyone is aware of how pious they are. There would have to be little or no ambiguity when it comes to just how devoted the ruler is the traditional religious system, or at least whatever religion is particularly popular in society.

Second, instead of simply saying that religion is useful to a ruler, Aristotle goes on to explain two important ways in which not simply religion, but that "uncommon devotion" to religion is. In both cases, it's a question of control: religion affects how people relate to one another and how they engage in social action. Religion has long proven helpful in regulating social behavior, something that will be particularly important to a tyrant who cannot necessarily count on the freely chosen support of his subjects.

When I warn people to stop believing those who show religiousness as a sign of goodness they never listen. A person who is likely to rub you of faith in life are those who present a fine face. We say "better the devil you  know than the angel you don't know," few look deep. Religion is the opium of the mass minded, expecting manna from heaven yet never putting an effort into making sure that it be sustained then eventually paying the price. When one tells people to apply themselves to something "anything" and be good at it we shout slavery, how about generating wealth from within? How about fighting for your right to self determination? Africa has worn out the name of God and takes every blessing as a curse, being reminded that they too could have done similar or remix what is given with what is already on ground.

Ideas, ideologies are a thought process, how workable are they depends on who sits at the will. No matter how much you fight for a religious belief to exist it will only stand the test of time when practiced. Be you a Christian, Muslim, Buddhist, scientist, Jedi at the end your faith in yourself and others makes life what it is.
