A more serious objection is that expertness is most readily attained in specialized technical matters, matters of administration and execution which postulate that general policies are already satisfactorily framed. It is assumed that the policies of the experts are in the main both wise and benevolent, that is, framed to conserve the genuine interests of society. The final obstacle in the way of any aristocratic rule is that in the absence of an articulate voice on the part of the masses, the best do not and cannot remain the best, the wise cease to be wise. It is impossible for high-brows to secure a monopoly of such knowledge as must be used for the regulation of common affairs. In the degree in which they become a specialized class, they are shut off from knowledge of the needs which they are supposed to serve. The strongest point to be made in behalf of even such rudimentary political forms as democracy has already attained, popular voting, majority rule and so on, is that to some extent they involve a consultation and discussion which uncover social needs and troubles. This fact is the great asset on the side of the political ledger. De Tocqueville wrote it down almost a century ago in his survey of the prospects of democracy in the United States. Accusing a democracy of a tendency to prefer mediocrity in its elected rulers, and admitting its exposure to gusts of passion and its openness to folly, he pointed out in effect that popular government is educative as other modes of political regulation are not. It forces a recognition that there are common interests, even though the recognition of what they are is confused; and the need it enforces of discussion and publicity brings about some clarification of what they are. The man who wears the shoe knows best that it pinches and where it pinches, even if the expert shoemaker is the best judge of how the trouble is to be remedied. Popular government has at least created public spirit even if its success in informing that spirit has not been great.
