 For Bosanquet, social work needed to be connected with education and, by extension, educational reform. Through his cousin Mary C. McCallum, Bosanquet learned about the Home Arts and Industries Association and its role in practical education and, starting in 1891, he frequently lectured and taught university extension courses for the London Ethical Society (LES)—initially under auspices of the University Extension Scheme at Essex Hall—and its successor, the short-lived London School of Ethics and Social Philosophy (1897–1900). Many of his publications, including The Essentials of Logic, A Companion to Plato’s Republic for English Readers, Psychology of the Moral Self, and The Philosophical Theory of the State, were based on or were prepared as texts for these courses.
