(Epilogue): Philosophers invariably assume a conception of self-knowledge when they discuss self-cultivation, but the precise relationship between self-knowledge and self-cultivation can be understood in different ways and often remains under-theorised. This epilogue examines how we can understand the relationship between self-knowledge and self-cultivation, making a case for what will be called a low-road explanation of the value of self-knowledge. To do this, the authors draw connections and contrasts with the chapters contained in the volume, and explore the idea that substantial self-knowledge—as opposed to trivial self-knowledge—deserves to be given more attention by contemporary philosophers.
