In "Why Does The World Exist? An Existential Detective Story," Jim Holt explores the question of why there is something rather than nothing. He interviews philosophers, scientists, and theologians to try to find an answer, delving into topics such as the nature of existence, the origins of the universe, and the meaning of life. Along the way, he examines various theories and arguments, from the Big Bang to the concept of God, in an attempt to uncover the ultimate explanation for the existence of the world.

"At The Existentialist Café" is a non-fiction book that explores the lives and ideas of a group of philosophers known as the existentialists. The book takes readers on a journey through the cafes of Paris in the 1930s and 40s, where philosophers such as Jean-Paul Sartre, Simone de Beauvoir, and Maurice Merleau-Ponty would gather to discuss their ideas about freedom, being, and the meaning of life. Bakewell weaves together their personal stories, philosophical theories, and the historical context in which they lived, to create a compelling and accessible introduction to existentialism.
