It has been always reckoned among the most difficult problems in the practical science of government, to combine an hereditary monarchy with security of freedom, so that neither the ambition of kings shall undermine the people's rights, nor the jealousy of the people overturn the throne. England had already experience of both these mischiefs. And there seemed no prospect before her, but either their alternate recurrence, or a final submission to absolute power, unless by one great effort she could put the monarchy for ever beneath the law, and reduce it to an integrant portion instead of the primary source and principle of the constitution. She must reverse the favoured maxim, "A Deo rex, à rege lex;" and make the Crown itself appear the creature of the law. But our ancient monarchy, strong in a possession of seven centuries, and in those high and paramount prerogatives which the consenting testimony of lawyers and the submission of parliaments had recognised, a monarchy from which the House of Commons and every existing peer, though not perhaps the aristocratic order itself, derived its participation in the legislature, could not be bent to the republican theories which have been not very successfully attempted in some modern codes of constitution. It could not be held, without breaking up all the foundations of our polity, that the monarchy emanated from the parliament, or even from the people. But by the revolution and by the act of settlement, the rights of the actual monarch, of the reigning family, were made to emanate from the parliament and the people. In technical language, in the grave and respectful theory of our constitution, the Crown is still the fountain from which law and justice spring forth. Its prerogatives are in the main the same as under the Tudors and the Stuarts; but the right of the house of Brunswick to exercise them can only be deduced from the convention of 1688.
