First principle
Love has an order
Universal dignity is real; our concrete obligations are particular and unequal in kind.
A parent owes a child what he does not owe a stranger. Citizens bear special duties toward countrymen while remaining bound to treat outsiders justly. Particular loyalty is not a moral defect but one of the ordinary forms through which care becomes real.
Not every moral obligation creates an unlimited enforceable right. A healthy commonwealth cultivates gratitude, generosity, service, and hospitality without converting every virtue into a centralized entitlement.
