The application of this principle to Parliamentary government is very plain; it shows at once that the intrusion from without upon an office of an exterior head of the office, is not an evil, but that, on the contrary, it is essential to the perfection of that office. If it is left to itself, the office will become technical, self-absorbed, self-multiplying. It will be likely to overlook the end in the means; it will fail from narrowness of mind; it will be eager in seeming to do; it will be idle in real doing. An extrinsic chief is the fit corrector of such errors. He can say to the permanent chief, skilled in the forms and pompous with the memories of his office, “Will you, Sir, explain to me how this regulation conduces to the end in view? According to the natural view of things, the applicant should state the whole of his wishes to one clerk on one paper; you make him say it to five clerks on five papers.” Or, again, “Does it not appear to you, Sir, that the reason of this formality is extinct? When we were building wood ships, it was quite right to have such precautions against fire; but now that we are building iron ships,” etc. , etc.
