John Stuart Mill

John Stuart Mill was a British philosopher and civil servant who lived from 1806 to 1873. His view of liberty justified individual liberty in opposed to unrestricted state control, making him a significant contributor to social theory, political theory, and political economy. He was a supporter of utilitarianism, an ethical theory founded by Jeremy Bentham, however he had a completely different interpretation of it than Bentham. He clearly stated the premises of falsification as a fundamental component in the scientific method in order to address the issues identified in an inductive approach to science, such as confirmation bias. Mill was also a Member of Parliament and a key influence in liberal political thought.

The person should be free to do as he likes until he harms others, according to John Stuart Mill, who was influenced by Joseph Priestley and Josiah Warren. Persons are logical enough to make decisions about their own well-being and to practice any religion they like. When it comes to the protection of society, the government should step in. According to Mill, the one purpose for which mankind is justified, individually or collectively, in interfering with any of their number's liberty of action is self-protection.

That the only legitimate reason for exercising control over a member of a civilized community against his will is to avoid harm to others. His own well-being, whether physical or moral, is insufficient justification. He cannot be coerced to do or refrain because it will be better for him, because it will make him happy, or because it would be prudent, or even right, in the judgment of others...The only portion of anyone's action that is acceptable to society is that which concerns others. His independence is absolute in the aspect of his life that just concerns him.

The individual is sovereign over himself, his own body and mind.
