This book essentially focuses on its title, namely the work "Unto This Last". This consists of four parts and is a critique of Victorian capitalism. So the book is largely concerned with the seemingly dry-as-dust topic of political economy. However, Ruskin was a polymath and a visionary so the essays are littered with references to art, architecture, classical history, Christian theology, foreign policy, geology, colour, etc etc. The breadth and depth of his knowledge and his manner of communicating it is astounding. Much of what he says has had a profound influence on 20th century life and each paragraph often contains a nugget of golden originality of thought or expression. All the other essays bear on the central "Unto This Last" but their subject-matters are eclectic, including his short parable "The King of the Golden River", excerpts from his thoughts on gothic architecture in "The Stones of Venice", a piece that compares Turner to Giotto, and open letters written to the working classes of England. Come the end, I could not but agree in Ruskin's philosophy that "There is no Wealth but Life".
