Paternalism refers to the practice of governing or managing individuals in a fatherly manner, often by making decisions for them under the belief that it is in their best interest. This concept suggests that authorities, such as governments or employers, may intervene in personal matters to ensure individuals' well-being, even if it limits personal autonomy. The justification for paternalism lies in the idea that individuals may not always know what is best for themselves, necessitating guidance from those deemed more knowledgeable. The discussion highlights the ethical implications of this doctrine, particularly in the context of Glover's work "Causing and Death and Saving Lives." Understanding paternalism is crucial for evaluating the balance between individual freedom and the role of authority in personal decision-making.
