Just as it's true that laws are inadequate for human behavior without morality, so too is it true that without etiquette, which is a kind of transition of good morality into life, morality remains nothing more than a theory. This means that it seems impossible to say that morality without etiquette, or laws without morality, can ensure happiness for individuals in this world and the hereafter.
If etiquette and rules are not observed in a society, it is impossible to talk about the existence of morality there; in societies where etiquette and morality are not given importance, it is also not possible to talk about respect for humans and therefore for the law, and of order and discipline.
For this reason, Manners is an important discipline that teaches people the rules of courtesy necessary to live as respected individuals in society, reveals the forms of measured and polite behavior to be followed in human relations, and includes the forms of speech, action and behavior that make the individual virtuous and worthy of respect in society.
