Children are, in many ways, born philosophers. Without prompting, they ask some of the largest questions about time, mortality, happiness and the meaning of it all. Yet too often this inborn curiosity is not developed and, with age, the questions fall away. This is a book designed to harness children's spontaneous philosophical instinct and to develop it through introductions to some of the most vibrant and essential philosophical ideas of history. The book takes us to meet leading figures of philosophy from around the world and from all eras - and shows us how their ideas continue to matter. The book functions as an ideal introduction to philosophy, as well as a charming way to open up conversations between adults and children about the biggest questions we all face.
