Fors Clavigera (Volume 4 of 8)
 Letters to the workmen and labourers of Great Britain

by John Ruskin

"Fors Clavigera (Volume 4 of 8)" by John Ruskin is a series of letters published during the 1870s. Addressed to British workmen and laborers, these pamphlets explore Ruskin's vision of moral value in sincere labor and social reform. Drawing inspiration from his mentor Thomas Carlyle, Ruskin tackles various topics aimed at influencing social change. The series famously includes his controversial attack on James McNeill Whistler's paintings, which led to a libel case that temporarily ended Ruskin's art criticism career.
