Abstract

Henry Sidgwick has gone down in the history of philosophy as both the great, classical utilitarian moral theorist who authoredThe Methods of Ethics, and an outstanding exemplar of intellectual honesty and integrity, one whose personal virtues were inseparable from his philosophical strengths and method. Yet this construction of Sidgwick the philosopher has been based on a too limited understanding of Sidgwick's casuistry and leading practical ethical concerns. As his friendship with John Addington Symonds reveals, Sidgwick was deeply entangled in an effort to negotiate the proper spheres of the public and private, not only in philosophical and religious matters, but also with respect to explosive questions of sexuality – particularly same sex actions and identities, as celebrated by Symonds and other champions of Oxford Hellenism and Whitmania. His willingness to mislead the public about such issues suggests that Sidgwick's utilitarian casuistry was rather more complex and esoteric than has been recognized.
