Liberty of conscience was the one great value which the common people had preserved from the Commonwealth. The countryside was ruled by the gentry, the towns by corruptcorporations, the nation by the corruptest corporation of all: but the chapel, the tavern and the home were their own. In the "unsteepled" places of worship there was room for a free intellectual life and for democratic experiments with "members unlimited". Against the background of London Dissent, with its fringe of deists and earnest mystics, William Blake seems no longer the cranky untutored genius that he must seem to those who know only the genteel culture of the time. On the contrary, he is the original yet authentic voice of a long popular tradition. If some of the London Jacobins were strangely unperturbed by the execution of Louis and Marie Antoinette it was because they remembered that their own forebears had once executed a king. No one with Bunyan in their bones could have found many of Blake's aphorisms strange: "The strongest poison ever known \ Game from Caesar's laurel crown."
