I cannot presume to speak of the time before the Conquest, and the exact nature even of all Anglo-Norman institutions is perhaps dubious: at least, in nearly all cases there have been many controversies. Political zeal, whether Whig or Tory, has wanted to find a model in the past; and the whole state of society being confused, the precedents altering with the caprice of men and the chance of events, ingenious advocacy has had a happy field. But all that I need speak of is quite plain. There was a great "council" of the realm, to which the king summoned the most considerable persons in England, the persons he most wanted to advise him, and the persons whose tempers he was most anxious to ascertain. Exactly who came to it at first is obscure and unimportant. I need not distinguish between the "magnum concilium in Parliament" and the "magnum concilium out of Parliament". Gradually the principal assemblies summoned by the English sovereign took the precise and definite form of Lords and Commons, as in their outside we now see them. But their real nature was very different. The Parliament of to-day is a ruling body; the mediaeval Parliament was, if I may so say, an EXPRESSIVE body. Its function was to tell the executive--the king--what the nation wished he should do; to some extent, to guide him by new wisdom, and, to a very great extent, to guide him by new facts. These facts were their own feelings, which were the feelings of the people, because they were part and parcel of the people. From thence the king learned, or had the means to learn, what the nation would endure, and what it would not endure;--what he might do, and what he might not do. If he much mistook this, there was a rebellion.
