Civic virtue refers to the set of habits, values, and attitudes that promote the general welfare and the effective functioning of a society. Closely linked to the concept of citizenship, civic virtue (virtus) represents, therefore, the disposition of citizens to put the common good (bonum commune) before special interests. The identification of the character traits that constitute civic virtue has been a major concern of political philosophy. The term civility refers to behavior between persons and groups that conforms to a social mode (that is, in accordance with the civil society), as itself being a foundation of society and law.
