, QUESTION 1
Nelson Mandela‟s 1962 courtroom statement captures one of the deepest questions
in legal philosophy, whether law and morality must go hand-in-hand. His words
highlight the inner turmoil of a person whose conscience compels him to resist an
unjust legal system. Mandela‟s view fits within the long-standing debate between
natural law theory, which sees morality as central to legal validity, and legal
positivism, which separates law from morality. His experience under apartheid is a
real-life example of how this debate is not only theoretical but also has personal,
ethical, and political consequences.
Natural Law
Natural law theory teaches that a law is only valid if it aligns with moral values that
are universal, unchanging, and eternal. This belief goes back to ancient Greek
philosophers like Plato and Aristotle. Plato believed the law should reflect higher
ideals, while Aristotle spoke of natural justice that binds all people, regardless of
legal systems. These thinkers saw natural law as the yardstick against which human
laws must be measured. If a law contradicts this ideal, it is not a real law.1
During the medieval period, thinkers such as Augustine and Thomas Aquinas
expanded on this. Aquinas taught that God‟s eternal law is revealed to humans
through reason and scripture. Human-made laws must reflect this moral code; if not,
they are seen as corrupt.2 This idea continued into modern legal theory with scholars
like Grotius and Blackstone, who both held that moral principles must guide the law.3
Mandela‟s statement reflects this view. He describes apartheid laws as “immoral,
unjust, and intolerable.” His conscience, shaped by moral reasoning, told him that
these laws were not just wrong but not law at all in the moral sense. He aligns with
natural law thinkers who say unjust laws are not valid laws.4
