These ten new essays by leading contemporary philosophers constitute the first collective study of a group of British moral philosophers active between the 1870s and 1950s, including Henry Sidgwick, Hastings Rashdall, G.E. Moore, H.A. Prichard, W.D. Ross, and A.C. Ewing. The essays help recover the history of this neglected period: they treat it as a unity, draw out the connections between the thinkers, engage philosophically with their ideas, and in so doing show how much they can contribute to present-day philosophical debates
