The Science of Moderation; or, The Quantitative Theory of the Good and the Beautiful. Formative Ethics

xii, 175 pp. A normative work on ethics referencing the golden mean, and discussing the definitions of the good and the beautiful as they relate to both morality and the fine arts. The author was a painter and sculptor who was friends with Dante Gabriel Rossetti and Ford Madox Brown, members of the Pre-Raphaelite Brotherhood. Some assert that Thomas provided the name for The Germ, a Pre-Raphaelite periodical (Paola Spinozzi and Elisa Bizzotto, The Germ: Origins and Progenies of Pre-Raphaelite Interart Aesthetics, Oxford, 2015, p. 22.).
