What it's about

In 1859 the philosopher John Stuart Mill argued that society may only limit a person's freedom to prevent harm to others, not to protect people from themselves or enforce majority opinion. He defends freedom of thought and speech, even for wrong opinions, and the right of individuals to live as they choose, warning against the 'tyranny of the majority'.

Why it's worth reading

It's on the Guardian's list of the best nonfiction of all time and is one of the foundations of liberal democracy. Its arguments are still at the center of debates about free speech.

Good to know

It's short but written in dense Victorian prose. Mill credited his wife, Harriet Taylor, as a co-thinker.
