Final answer:
John Stuart Mill's utilitarianism identifies actions as right if they promote overall happiness, but acknowledges the challenge of balancing individual freedom with societal good. His harm principle guides this balance, allowing freedom unless it causes harm to others.
Step-by-step explanation:
The ethical theory of John Stuart Mill, known as utilitarianism, emphasizes the outcomes of actions, suggesting that actions that promote the greatest happiness for the greatest number are considered morally right. One issue with freedom according to Mill is the potential conflict between individual rights and the overall happiness of society. His harm principle is meant to maximize freedom by allowing any action unless it harms others, a principle that supports his advocacy for positions like freedom of speech.
