In 1859, philosopher John Stuart Mill published 'On Liberty', a pivotal work defending individual freedom and free speech against the 'tyranny of the majority'. Mill argued that eccentricity and dissent are essential for social progress, emphasizing the importance of protecting minority opinions. His ideas have had a profound influence on liberal thought, shaping discussions about civil liberties and the role of government in personal freedoms.

John Stuart Mill's 'On Liberty' provided a philosophical foundation for non-conformist voices in poetry. His advocacy for individual freedom resonated with avant-garde poets, encouraging them to challenge societal norms and explore themes of rebellion in their work.
