The Tyranny of the Majority: Mill's Timeless Warning

In 1859, a slim volume appeared that would fundamentally reshape our understanding of freedom. When Barack Obama was asked which book most influenced his political thinking, he named this one: John Stuart Mill's "On Liberty." Despite being over 160 years old, its arguments feel startlingly relevant in our age of cancel culture, social media conformity, and political polarization. At its core lies a radical question: What happens when democracy itself becomes oppressive? Mill identified a danger more insidious than government censorship-the crushing weight of social conformity that silences dissent and stifles human development. As tech entrepreneur Peter Thiel observed, "Mill's warning about social conformity feels more urgent today than when he wrote it."
