Final answer:
Post-conventional morality is Kohlberg's highest stage of morality, occurring late in life, where an individual develops a personal morality that goes beyond society's rules and restrictions.
Step-by-step explanation:
The highest stage of morality in Kohlberg's theory is post-conventional morality. This stage typically occurs late in life and involves the development of a personal morality that supersedes society's rules, laws, and restrictions. In this stage, individuals prioritize values such as justice, equality, and human rights over strictly following the laws and norms of society. An example of this stage is when someone believes that saving a life is more important than obeying a law or rule that may prevent it, as in the case of Heinz stealing medicine for his dying wife.
