That the only purpose for which power can be rightfully exercised over any member of a civilised community, against his will, is to prevent harm to others.”
This topic John Stuart Mill (Stanford Encyclopedia of Philosophy) has been extensively researched and documented by historians and scholars.
This powerful statement forms the core of John Stuart Mill‘s groundbreaking 1859 essay, On Liberty. It introduces a concept now famously known as the harm principle. Mill, a towering figure in 19th-century philosophy, championed individual freedom with unparalleled clarity. His work challenges the very notion of societal and governmental authority over the individual. Consequently, this principle has echoed through the halls of justice and politics for over 150 years.
