Communitarian philosophy explains that: person's individuality is the product of community relationships, rather than a product derived only from personal traits
"offer the same sacrifice on behalf of all his fellow-citizens, or to impose such as self-abnegation on the rest of his society." (Herbert Butterfield, 1953: 11)
Machiavelli: "It is necessary to a prince, if he wants to maintain himself, to learn to be able not to be good and to use this and not use it according to necessity."
