It is worth our while to read and reread the preamble of the Constitution, and Article I thereof which confers the legislative powers upon the Congress of the United States. It is also worth our while to read again the debates in the Constitutional Convention of one hundred and fifty years ago. From such reading, I obtain the very definite thought that the members of that Convention were fully aware that civilization would raise problems for the proposed new Federal Government, which they themselves could not even surmise; and that it was their definite intent and expectation that a liberal interpretation in the years to come would give to the Congress the same relative powers over new national problems as they themselves gave to the Congress over the national problems of their day. In presenting to the Convention the first basic draft of the Constitution, Edmund Randolph explained that it was the purpose "to insert essential principles only, lest the operation of government should be clogged by rendering those provisions permanent and unalterable which ought to be accommodated to times and events." With a better understanding of our purposes, and a more intelligent recognition of our needs as a Nation, it is not to be assumed that there will be prolonged failure to bring legislative and judicial action into closer harmony. Means must be found to adapt our legal forms and our judicial interpretation to the actual present national needs of the largest progressive democracy in the modern world. That thought leads to a consideration of world problems. To go no further back than the beginning of this century, men and women everywhere were seeking conditions of life very different from those which were customary before modern invention and modern industry and modern communications had come into being. The World war, for all of its tragedy, encouraged these demands, and stimulated action to fulfill these new desires. Many national Governments seemed unable adequately to respond; and, often with the improvident assent of the masses of the people themselves, new forms of government were set up with oligarchy taking the place of democracy. In oligarchies, militarism has leapt forward, while in those Nations which have retained democracy, militarism has waned. I have recently visited three of our sister Republics in South America. The very cordial receptions with which I was greeted were in tribute to democracy. To me the outstanding observation of that visit was that the masses of the peoples of all the Americas are convinced that the democratic form of government can be made to succeed and do not wish to substitute for it any other form of government. They believe that democracies are best able to cope with the changing problems of modern civilization within themselves, and that democracies are best able to maintain peace among themselves.
