 Even such influential critics of utilitarianism as William Frankena, Marcus Singer, and John Rawls have looked to Sidgwick’s work for guidance. C. D. Broad, a later successor to Sidgwick’s Cambridge chair, famously went so far as to say “Sidgwick’s Methods of Ethics seems to me to be on the whole the best treatise on moral theory that has ever been written, and to be one of the English philosophical classics” (Broad 1930: 143). In recent years, Broad’s assessment has been endorsed by an increasing number of prominent philosophers (Parfit 2011; de Lazari-Radek &amp; Singer 2014; and Crisp 2015). Engaging with Sidgwick’s work remains an excellent way to cultivate a serious philosophical interest in ethics, metaethics, and practical ethics, not to mention the history of these subjects. Moreover, he made important contributions to many other fields, including economics, political theory, classics, educational theory, and parapsychology. His significance as an intellectual and cultural figure has yet to be fully appreciated, but recent years have witnessed an impressive expansion of Sidgwick studies, and he has even been featured in popular novels (Cohen 2010; Entwistle 2014).
