Paternalism refers usually to an attitude or a policy stemming from the hierarchic pattern of a family based on patriarchy, that is, there is a figurehead (the father, pater in Latin) that makes decisions on behalf of others (the "children") for their own good, even if this is contrary to their wishes.
It is implied that the fatherly figure is wiser than and acts in the best interest of its protected figures. The term may be used derogatorily to characterize attitudes or political systems that are thought to deprive individuals of freedom and responsibility, only nominally serving their interests, while in fact pursuing another agenda.
