[In the following pages Lord Beaconsfield expounds that theory of the English Constitution which he had previously set forth in his pamphlet ‘A Vindication of the English Constitution in a Letter to a Noble and Learned Lord.’ The same theory is expounded in another way in the three great novels, ‘Coningsby,’ ‘Sybil,’ and ‘Tancred.’ His contemporaries never seem to have understood it, while his assailants of a later date appear to have written and spoken concerning him in absolute ignorance of his real political creed. The concluding paragraph of the tract ought, in the minds of all candid men, to disperse at once and forever the innumerable calumnies levelled at Lord Beaconsfield during and since the Reform struggle of 1859-1867.]
