A parliamentary government chosen on the party system is, as we have seen, at once the trustee of the whole nation, bound as such to make the welfare of the whole its supreme end, and also the special representative of particular classes, the special guardian of their interests, aims, wishes, and principles. The two points of view are not the same, and grave difficulties, both ethical and political, have often to be encountered in endeavouring to harmonise them. It is, of course, not true that a party object is merely a matter of place or power, and naturally a different thing from a patriotic object. The very meaning of party is that public men consider certain principles of government, certain lines of policy, the protection and development of particular interests, of capital importance to the nation, and they are therefore on purely public grounds fully justified in making it a main object to place the government of the country in the hands of their party. The importance, however, of maintaining a particular party in power varies greatly. In many, probably in most, periods of English history a change of government means no violent or far-reaching alteration in policy. It means only that one set of tendencies in legislation will for a time be somewhat relaxed, and another set somewhat intensified; that the interests of one class will be somewhat more and those of another class somewhat less attended to; that the rate of progress or change will be slightly accelerated or retarded. Sometimes it means even less than this. Opinions on the two front benches are so nearly assimilated that a change of government principally means the removal for a time from office of ministers who have made some isolated administrative blunders or incurred some individual unpopularity quite apart from their party politics. It means that ministers who are jaded and somewhat worn out by several years' continuous work, and of whom the country had grown tired, are replaced by men who can bring fresher minds and energies to the task; that patronage in all its branches having for some years gone mainly to one party, the other party are now to have their turn. There are periods when the country is well satisfied with the general policy of a government but not with the men who carry it on. Ministers of excellent principles prove inefficient, tactless, or unfortunate, or quarrels and jealousies arise among them, or difficult negotiations are going on with foreign nations which can be best brought to a successful termination if they are placed in the hands of fresh men, unpledged and unentangled by their past. The country wants a change of government but not a change of policy, and under such circumstances the task of a victorious opposition is much less to march in new directions than to mark time, to carry on the affairs of the nation on the same lines, but with greater administrative skill. In such periods the importance of
