There is every reason to expect that a Parliamentary statesman will be a man of quite sufficient intelligence, quite enough various knowledge, quite enough miscellaneous experience, to represent effectually general sense in opposition to bureaucratic sense. Most Cabinet Ministers in charge of considerable departments are men of superior ability; I have heard an eminent living statesman of long experience say that in his time he only knew one instance to the contrary. And there is the best protection that it shall be so. A considerable Cabinet Minister has to defend his department in the face of mankind; and though distant observers and sharp writers may depreciate it, this is a very difficult thing. A fool, who has publicly to explain great affairs, who has publicly to answer detective questions, who has publicly to argue against able and quick opponents, must soon be shown to be a fool. The very nature of Parliamentary government answers for the discovery of substantial incompetence.
