JOHN RUSKIN: 

(1819-1900) He was mainly an art critic and influenced public taste in Victorian England. In later life he became very critical of the political economy of his time and championed the cause of workers. His major works are: Modern Painters (1843), The Seven Lamps of Architecture (1849), and The Stones of Venice (1851-1853).
In "the Stones of Venice" Ruskin states his opinion about the division of labour in the Victorian industrial system, which comes from the relation between master and worker in feudal times. He thinks that the degradation of worker into a machine is one of the most important causes of the destructive struggling for freedom among classes and that with the invention of the division of labour men are divided into "mere segments of men, little pieces of intelligence". He says that only by understanding what kind of labour is good for individual men, then he can be happy.
