The vital lines of cleavage among our people do not correspond, and indeed run at right angles to, the lines of cleavage which divide occupation from occupation, which divide wage-workers from capitalists, farmers from bankers, men of small means from men of large means, men who live in the towns from men who live in the country; for the vital line of cleavage is the line which divides the honest man who tries to do well by his neighbor from the dishonest man who does ill by his neighbor. In other words, the standard we should establish is the standard of conduct, not the standard of occupation, of means, or of social position. It is the man's moral quality, his attitude toward the great questions which concern all humanity, his cleanliness of life, his power to do his duty toward himself and toward others, which really count; and if we substitute for the standard of personal judgment which treats each man according to his merits, another standard in accordance with which all men of one class are favored and all men of another class discriminated against, we shall do irreparable damage to the body politic. I believe that our people are too sane, too self-respecting, too fit for self-government, ever to adopt such an attitude. This Government is not and never shall be government by a plutocracy. This Government is not and never shall be government by a mob. It shall continue to be in the future what it has been in the past, a Government based on the theory that each man, rich or poor, is to be treated simply and solely on his worth as a man, that all his personal and property rights are to be safeguarded, and that he is neither to wrong others nor to suffer wrong from others. The noblest of all forms of government is self-government; but it is also the most difficult. We who possess this priceless boon, and who desire to hand it on to our children and our children's children, should ever bear in mind the thought so finely expressed by Burke: "Men are qualified for civil liberty in exact proportion to their disposition to put moral chains upon their own appetites; in proportion as they are disposed to listen to the counsels of the wise and good in preference to the flattery of knaves. Society cannot exist unless a controlling power upon will and appetite be placed somewhere, and the less of it there be within the more there must be without. It is ordained in the eternal constitution of things that men of intemperate minds cannot be free. Their passions forge their fetters." The great insurance companies afford striking examples of corporations whose business has extended so far beyond the jurisdiction of the States which created them as to preclude strict enforcement of supervision and regulation by the parent States. In my last annual message I recommended "that the Congress carefully consider whether the power of the Bureau of Corporations cannot constitutionally be extended to cover interstate transactions in insurance."
