Jörg Baberowski provides a well-founded overview of influential thinkers and movements in 19th and 20th-century philosophy, illustrating the significance of their theories for the everyday life of historians through concrete case studies. His particular focus is on those philosophical theories that can shed light on the methods by which the subject of history can be explored. It is a clearly written introduction to fundamental questions of modern historical theory from Hegel to Foucault.
