While he seldom wrote directly of politics, William Blake was associated with the young radicals in the late eighteenth and early nineteenth centuries that lionized the American and especially the French Revolutions and hoped that they pointed the way for increased democratization of English government. He moved in the same circles as such noted radicals as Mary Wollstonecraft, Thomas Paine, and Richard Price, all of whom saw events in France as the harbinger of similar events to come in England. Blake also published a highly sympathetic account of the French Revolution. He was known to be an opponent of the established church in England and a supporter of civil liberties. Above all, he championed the individual, and saw the world he lived in as a changing place, in which people would become freer.
william blake is critical about the interfearence of politics with the church. ( see the poem Garden of love) there he talks about the institutionalized church where politics and leaders have a greater influence on the church resulting men to be away from the religion. yes, his view are radical.
