While in prison, Malcolm X read furiously after lights-out and changed his entire life trajectory. Naomi Alderman looks at his extraordinary capacity for learning. Prominent as a black nationalist, skilled orator and remarkable organiser in the black freedom struggle in mid-20th century America, Malcolm X was, above all, a learner – a thinker prepared to change his mind. He left hustling behind for a Spartan, ascetic existence, dedicated to the cause.

Luther's vivid, wild words – powered by new printing technology – set in motion a chain reaction that split the Catholic Church, powered the Reformation and changed the world forever. Naomi Alderman meets this determined thinker.

Famously, Luther walked up to a church in a backwater town and nailed his Ninety-five Theses to the door. The son of a metal smelter, he knew how rough and dangerous life could be; and he was prepared to question, argue and openly insult powerful authorities in defence of his explosive theology.

Mary Wollstonecraft argued with passion and moral certainty in her great work, A Vindication of the Rights of Women. Naomi Alderman meets the first modern woman, who lived the ideas she espoused – travelling to revolutionary France, living unmarried to her lover, arguing, debating, persuading and showing, with the quality of her arguments, the justice of her own cause. She died tragically young, giving birth to her daughter Mary, known now as Mary Shelley, the author of Frankenstein.
