"As a matter of fact, the enormous mass of our legislation and administration ought to be concerned with matters that are strictly for the commonweal; and where special legislation or administration is needed, as it often must be, for a certain class, the need can be met primarily by mere honesty and common sense. But if men are elected solely from any caste, or on any caste theory, the voter gradually substitutes the theory of allegiance to the caste for the theory of allegiance to the commonwealth as a whole, and instead of demanding as fundamental the qualities of probity and broad intelligence—which are the indispensable qualities in securing the welfare of the whole—as the first consideration, he demands, as a substitute, zeal in the service, or apparent service, of the class, which is quite compatible with gross corruption outside. In short, we get back to the conditions which foredoomed democracy to failure in the ancient Greek and medieval republics, where party lines were horizontal and class warred against class, each in consequence necessarily substituting devotion to the interest of a class for devotion to the interest of the state and to the elementary ideas of morality. The only way to avoid the growth of these evils is, so far as may be, to help in the creation of conditions which will permit mutual understanding and fellow-feeling between the members of different classes. To do this it is absolutely necessary that there should be natural association between the members for a common end or with a common purpose. As long as men are separated by their caste lines, each body having its own amusements, interests, and occupations, they are certain to regard one another with that instinctive distrust which they feel for foreigners. There are exceptions to the rule, but it is a rule."
