In Dear Friend, you must change your life, we see some of the most fascinating thinkers in history at their most private and profound, reaching out to a friend, sharing, testing, confirming discoveries about the complexity of life, how to rise above its hardships and enjoy its pleasures. We see writers embrace the roots of philosophical thought afresh, by grappling with real, lived experience, giving us unique insight into their ideas and worldviews that their more polished, public work often does not provide. We see artists sound the foundations of their artistic and moral integrity.

Ranging from Seneca and Marcus Aurelius to Flora Tristan and Walter Benjamin, to Elizabeth of Bohemia and Giacomo Leopardi, to Mahatma Gandhi and Maurice Bejart, we see how the philosophical letter as a form of thinking, and thinking freely, spans across the ages and often forms some of the most interesting and lively of philosophical writings. 

Each letter is given a contextualising preface by an expert that brings out the reason this particular letter is a philosophical letter for life. As such, Dear Friend, you must change your life provides a unique introduction to an array of thinkers throughout history as well as an argument for philosophy as conversation, a conversation which has been ongoing for centuries.
