What did William Blackstone believe in?

William Blackstone (1723-1780) was an English jurist and author of probably the most influencial book on English Common Law, Blackstone's Commentaries. In the commentaries, he affirms his support for the constitutional concept that the legislature is supreme, and not subject to the surveillance of the monarch or judiciary. However, in politics he avowed himself to be a Tory, which theoretically meant that the legislature was not supreme over the monarch. This contradiction may be explained by the fact that during the eighteenth century Toryism was essentially a spent political force and its principles considerably diluted.
