Final answer:
Nelson Mandela refers to twin obligations as the duty to oneself and others, especially in the context of opposing unjust or corrupt governments, as exemplified in his fight against apartheid in South Africa.
Step-by-step explanation:
The "twin obligations" that Nelson Mandela discusses refer to the duties that individuals have both towards themselves and towards others. In the context of political and ethical theory, these obligations are particularly important when considering the actions and responsibilities of individuals within a society. Mandela, like other activists such as Mahatma Gandhi, believed that there is a duty to disobey corrupt or unjust governments. This is rooted in a higher moral obligation to serve and protect the integrity and well-being of oneself and others, even if it means opposing the legal structures and regulations imposed by the state. Mandela's own fight against the apartheid regime in South Africa exemplifies these twin obligations as he both served his own convictions and the greater good of his country's people.
