Elizabeth Finch was a teacher, a thinker, an inspiration - always rigorous, always thoughtful. With measured empathy, she guided her students to develop meaningful ideas and to discover their centres of seriousness.

As Neil, a former student, unpacks Elizabeth's notebooks, and remembers her uniquely inquisitive mind, her passion for reason resonates through the years. Her ideas unlock the philosophies of the past, and explore key events that show us how to make sense of our lives today. And underpinning them all is the story of J - Julian the Apostate, her historical soulmate and fellow challenger to the institutional and monotheistic thinking that has always threatened to divide us.
