"It is not at all certain that a merely moral criticism of society may not be just as "revolutionary" — and revolution, after all, means turning things upside down — as the politico-economic criticism which is fashionable at this moment. Blake was not a politician, but there is more understanding of the nature of capitalist society in a poem like "I wander through each charter'd street" than in three-quarters of Socialist literature."
