In these two ways, then;—first, through the culmination of national deliberation among a selected group of representatives, among whom again custom and tradition accord precedence and prestige to the natural leaders, the most able and those in whose consciousness the nation, in the past, present and future is most adequately reflected; secondly, by means of the party system, which ensures vigorous criticism and full discussion of all proposals, under a system of traditional conventions evolved for the regulation of such discussions;—in these two ways the principal vices of collective deliberation are corrected, and the formal deliberations and decisions of the nation are raised to a higher plane than the collective deliberations of any assembly of men lacking such traditional organisation could possibly attain. The part played by unwritten tradition in the working of the British constitution is of course immense, as for example, the existence and enormous prestige of the cabinet, and the tradition that a party coming into power must respect the legislation of the party previously in power. Without this last, representative government, or at any rate the party system, would be impossible. The smooth working of the system depends entirely upon the influence of these and similar traditions which exist only in the minds of men. Or, take as another example, the tradition of absolute impartiality on the part of the Speaker and of loyal acceptance of his rulings by every member of the House; or the tradition which distinguishes sharply between political and private relations, in virtue of which the parties to a most bitter political strife may and very generally do remain in perfectly friendly private relations.
