Utilitarianism

Mill's 1859 defense of individual freedom and the source of the harm principle: society may only limit what you do to prevent harm to others. Short, clear and still the starting point of every debate on free speech.

John Stuart Mill

Three essays published after Mill's death in 1874, on whether nature can be a moral guide, what religion is good for and how much a thinking person can believe about God. His most personal writing on faith.
