Full Idea
Rousseau's idea of popular sovereignty is a much more radical idea of self-government, because he insists that the consent of the people has to have a real means of expression.
Gist of Idea
Rousseau insists that popular sovereignty needs a means of expressing consent

A Reaction
Presumably Hobbes's 'contract' is forgotten in the mists of time, and ceases to be of any interest to a ruler (such as Charles I, who thought God must have appointed him). Perhaps Britain needs an annual ceremony reaffirming the monarch.
