‘On all great subjects’, says Mr Mill, ‘much remains to be said’, and of none is this more true than of the English Constitution. The literature which has accumulated upon it is huge. But an observer who looks at the living reality will wonder at the contrast to the paper description. He will see in the life much which is not in the books; and he will not find in the rough practice many refinements of the literary theory.

It was natural – perhaps inevitable – that such an undergrowth of irrelevant ideas should gather round the British Constitution. Language is the tradition of nations; each generation describes what it sees, but it uses words transmitted from the past. When a great entity like the British Constitution has continued in connected outward sameness, but hidden inner change, for many ages, every generation inherits a series of inapt words – of maxims once true, but of which the truth is ceasing, or has ceased. As a man's family go on muttering in his maturity incorrect phrases derived from a just observation of his early youth, so, in the full activity of an historical constitution, its subjects repeat phrases true in the time of their fathers, and inculcated by those fathers, but now true no longer. Or, if I may say so, an ancient and ever-altering constitution is like an old man who still wears with attached fondness clothes in the fashion of his youth: what you see of him is the same; what you do not see is wholly altered.
