The publication of John Stuart Mill's Three Essays on Religion in 1873 prompted a remarkable diversity of responses. Anonymous authors in the prominent literary and theological reviews of the day joined philosophers, from empiricists to idealists, and theologians, from Anglicans to Unitarians, in commenting on the Essays. The judgements passed upon Mill himself ranged from 'honest' to 'impudent'. Dr Sell here gathers and introduces a representative selection of the reviews, essays and extracts that met this important work. The writers, although diverse, are at least united in one view - that what Mill had written mattered - and their debate continued for many years - the contributions cover a quarter of a century of controversy.
